Inpipe Sweden AB
Inpipe has provided solutions for pipe renewal for over 30 years. 1977 The first patent application was made for a system for weaving fibreglass threads to create a flexible sock. A number of years of product development followed, and in 1982 a system was developed with polyester resin, in which hardening was carried out with UV light. 1985 saw the creation of Inpipe AB with in the same year the first commercial installation of an Inpipe liner in a wastewater pipe. In the first few years, all production took place in small rented premises, but in 1988 the production plant in Vilhelmina was completed and inaugurated. All product development and production have taken place here since. In 1995 Inpipe obtained its first ISO certification and we have worked hard since then to achieve constant improvements in our products and activities.

You will find Inpipe Sweden AB in Vilhelmina, in the heart of Lapland, right on the border of the magnificent mountain area. We have worked here for more than 30 years.
We are proud of our northern origins and we are convinced that it has brought us to where we are today.
1977 The first patent application was made for a system for weaving fibreglass threads to create a flexible sock. A number of years of product development followed, and in 1982 a system was developed with polyester resin, in which hardening was carried out with UV light. 1985 saw the creation of Inpipe AB with in the same year the first commercial installation of an Inpipe liner in a wastewater pipe.

All product development and production have taken place here since. In 1995 Inpipe obtained its first ISO certification and we have worked hard since then to achieve constant improvements in our products and activities.
Today, Inpipe has an effective and modern factory in which we develop and produce all of our liners in diameters from 150 mm up to an impressive 1800 mm. Our home market is the Nordic region, but we supply our products to large parts of Europe.
Inpipe Sweden AB is 100% owned by the Danish construction company Ove Arkil A/S, which has more than 2000 employees and an annual turnover of around 3.3 billion Danish kronor.
Who really cares about sewers?
Our modern society depends on an efficient pipeline network for water and sewerage. We all want clean water for our homes, and it must be possible for the wastewater to be transported to the treatment plant to be processed. If this circuit doesn’t work, a number of problems can arise.
Leaks, blockages and overflows in wastewater pipes are common. This can lead to many unpleasant results and cause major costs and challenges for municipalities as they must be remedied rapidly. If you’re lucky simply rinsing the pipe and removing soil, roots or other obstacles will do the trick. If you’re unlucky, you have to dig up and replace the pipe – which of course is very expensive and takes a long time to do.
Large parts of our wastewater system are considered to be a ticking economic bomb as they are old and worn and need to be renovated. However, it’s widely felt that the rate of renovation is far too slow. At this renovation rate, it’s estimated that it will take around 250 years before all pipes in Sweden have been replaced. The lifetime of a wastewater system is often stated as 50 to 100 years. So the figures just don’t add up!
The majority of people think that sewers are an extremely unpleasant environment. We do too, to be honest. But we love to solve the problems presented by bad pipes.
With our installers, products and knowledge in the field of trenchless renovation, here at Inpipe Sweden AB we can help you achieve a secure, watertight and functioning wastewater system. Here we explain how you can give new life to your old pipes.
What does quality mean to you?
The question can be difficult to answer simply. That the product works as intended and gives a good end result is self-evident, but quality is so much more. We constantly listen to our customers, and our objective is for you to obtain what you are seeking - and ideally a little more. It’s not always easy, but we work constantly with improvements to fulfil your needs and desires.
As a customer, you should be confident that you will get:
- The dimensions you have ordered
- The ring stiffness you have ordered
- The product type you have ordered
- Delivery at the right time and to the right place
- The right invoice
- The right support and service at the right time
Quality also involves other things, so we also give you:
- Effective installation methods
- Products that can be handled effectively
- Clear instructions and appropriate training
- Minimal environmental impact
- A good work environment and high safety levels
We quality assure all stages of our operations. From strict quality requirements and monitoring of materials from our suppliers to high levels of care when packaging your products.
Through a number of tests, our own laboratory personnel constantly ensure that materials and products fulfil our tough quality requirements before they are sent to you. We have also developed systems to find shortcomings and opportunities for constant improvement and development of our activities and products.
Naturally we are certified according to ISO 9001, and have been since 1995.
ISO 9001 is a management system standard for quality processes in a company or organisation. It can affect everything from how we answer the telephone to how we avoid operational disruptions.
The management system describes how we constantly improve and adjust our activities to fulfil our customers’ needs.ISO 9001 is based on seven principles:
- Customer focus
- Employee commitment
- Process orientation
- Fact-based decisions
- Relationship management
To be ISO certified requires first and foremost a management system and thereafter that we fulfil the requirements set by the current standard.
Inpipe has a well-developed environmental policy which controls our everyday work with a focus on minimising the environmental impact of our activities.
Today we know more about the things that negatively and positively affect our environment. Around the world, scientific work is being carried out to find facts upon which we can base changes and decisions. For many people it can be difficult to absorb this information, and it is not always easily accessible.
It can therefore be difficult to evaluate and make decisions regarding which methods and products give particular results. In this section we try to help you to easily understand what generates more or less emissions in our industry. Read more in the menu on the right.
Inpipe’s liners consist of a composite of polyester and fibreglass enclosed in two plastic foils. The plastic consists both of polyester resin but also of foils manufactured from PP, PE and PU.
Environmental impact from plastic composites
Plastic is usually a petroleum product. In other words, it is manufactured from oil. Plastic has a number of advantages. It allows us to make products and solutions that produce higher energy efficiency than if other materials were used.
Plastic can be reinforced or in other ways given a high resistance, which means that many plastic products contribute to reduced material use and lower weight in finished products.
According to one study, due to their energy efficiency in production, effective production processes and reduction of material use, plastics contribute to a reduction of oil consumption corresponding to 50 million tonnes of crude oil per year, corresponding to permanently removing around 49 million cars from circulation. Plastic use today represents around 4% of the global use of fossil fuels. According to the study, an increase of the use of plastics could contribute to further reducing emissions of greenhouse gases due to their characteristics during manufacture and in the end product. (Source)
This can be compared with the manufacture of cement, which is a component of concrete and represents 5% of global emissions. (Source) To then manufacture concrete requires additional material in the form of crushed gravel or similar substances together with transport of heavy material. Nor is there any reliable data that shows the quantity of emissions generated by concrete manufacture.
All manufacturing generates emissions during different phases of the process, which includes the manufacture of composite material. Depending on the content of the composite, the emissions will vary in size, but due to their life expectancies and low weight compared with other materials, emissions are reduced when a lifecycle analysis is carried out. (Source)
One metre of concrete pipe of inner diameter 225 mm weighs approximately 120 kg/m; the corresponding pipe for relining weighs approximately 5 kg/m. It is therefore clear that emissions from transport and handling are higher for the concrete pipe.
Compared with traditional excavation, with our no-dig methods you can reduce your emissions of carbon dioxide by up to 80%.
Save up to 80% of emissions
When you choose Inpipe’s trenchless renovation method for your pipes instead of excavating, you can save up to 80% in carbon dioxide emissions and you obtain a sustainable product. For us, a sustainable investment means that it should be as environmentally friendly as possible, economically advantageous and give you a long expected product lifetime.
You wouldn’t drive your car around the world 5.5 times for no reason, would you?
Here’s an example. You renovate 100 metres of wastewater pipe at a depth of 4 metres. If you choose Inpipe’s products and installation methods instead of excavating, you can reduce emissions by approximately 28,000 kg of carbon dioxide*. This corresponds to the amount of carbon dioxide for a new car** driven 220,000 km, which is about 5.5 times around the world, or 18 years’ driving for an average Swedish car***.
You get more for your money
The fact that renovation using Inpipe liners can give you 25-80% lower costs compared to traditional excavation is almost self-evident in this context. In addition, the Inpipe product is designed to give you an expected lifetime of up to 100 years, which is economically sustainable.
Make the right choice for the sake of the environment.
Trenchless renovation of pipes using Inpipe’s technology generates much more limited disruptions in the surrounding community. It is quick and often only requires you to open a manhole cover, which requires minor closures. Often traffic and other functions can continue as usual during the work.
Installation with Inpipe
What it can look like when you dig up a pipe
* The estimated CO2 emission from excavation is based on a section of street, all excavation taking place in asphalt streets and with pipe excavations designed according to AMA. Excavation soils are transported to intermediate storage in the nearby area. Gravel is used for the pipe bed and backfill and the asphalt is restored on refilled and packed soils.
** According to the Swedish Transport Administration, the average emissions for a new car registered in Sweden in 2015 are 127 g CO2/km.
*** According to Transport Analysis, which works on behalf of the Swedish government, in 2015 the average driving distance per year for a car registered in Sweden was 12220 km/year.
We are surrounded by Europe's last wilderness. So respect for the environment is completely natural to us!
For us it is also natural that we have a clear focus on caring for our environment in our work. We have a clear environmental policy and collaborate closely with authorities and organisations on environmental issues.
Our lowest level is requirements according to laws and from authorities. Beyond this, we do everything we can to reduce our environmental impact within an economically justifiable framework. A few examples:
We continuously reduce our use of chemicals and solvents, as this saves both the environment and costs.
We apply a recycling system for the packaging we send our liners out in. This means, quite simply, that you can get money back if/when you send back the packaging. This system is also applied in certain parts of our installation system.
We try as far as possible to combine product deliveries to you as this is more effective from a transport viewpoint and reduces emissions from the transport.
Inpipe always works to reduce environmentally hazardous emissions from our production, transports and products.
When you buy from us you’re buying a product which is as environmentally friendly as possible. We achieve this by continuously setting goals for reducing emissions and environmental load in the entire chain from raw material to finished, installed product.
The fact that manufacturing of any form of product affects the environment in some way is unavoidable. For this reason, our mission is as far as possible to streamline production and reduce total emissions from our products.
Inpipe’s products consist of fibreglass, polyester and foils.
We make our liners as thin and light as possible – this leads to lower consumption of materials and smaller emissions from manufacture and transports. We constantly seek ways to reduce our consumption of chemicals in our production, or replace them with more environmentally friendly products.
- Fibreglass: Is manufactured from a glass type in which the use of flux has been reduced, in order to reduce environmentally hazardous emissions.
- Polyester: Used in liquid form. Polyester must contain a solvent, often styrene. In our production, we have continuously reduced the use and emissions of solvents.
- Products based on polyester are entirely free from Bisphenol A.
- Foils: The plastic foils used in the product are, as far as possible, manufactured from plastics that can be recycled in some way with minimal hazardous emissions.
As far as possible, we strive to coordinate all of our transports, both when purchasing materials and during delivery of products to the customer, in order to reduce environmental loads. Purchasing of raw materials is carried out as far as possible in large quantities.
The installed product
When our product has been installed, the polyester is hardened using UV light. This means that the styrene in the polyester is bound and consumed. A hardened product contains less than 2% residual styrene. The emissions are minimal. Hardening with UV light is very energy-efficient compared to hardening using steam or hot water.
