Asahi/America Application Story – Chemical Processing
A large manufacturer of printing ink needed a high purity piping system to produce a new prototype of ink. The DI Water System called for a continuous loop system and required strict adherence to a low TOC. Asahi's Purad PVDF Piping System was chosen due to its low leachout ratings and the ability of the zero deadleg valves to reduce the possibility of bacteria build-up within the loop. ...

Top Tips - How to Select the Right Expansion Joints
Expansion joints don’t always get the attention they deserve. They are critical components of piping systems for every industry. These flexible connectors allow for movement within the piping system. They can also minimize vibration and sound. Expansion joint failure can result in process downtime as well as safety or environmental concerns, so ensuring the right joints are installed is ...

Asahi/America Application Story – Railroad
CSX's underground air brake system was corroding. They had thousands of feet of pipe in the ground that was beginning to fail. The system was failing as a result of their current system's inability to withstand their application's physical demands. They had to find a piping system that was rugged, durable, resistant to corrosion and cost effective. Asahi/America had what they ...

Anomaly pre-localization in distribution–transmission mains by pump trip: preliminary field tests in the Milan pipe system
In this paper, the reliability of transients due to pump trip as a powerful tool for the pre-localization of anomalies in real pipe systems is tested. The examined pipe system is part of the one supplying the city of Milan, Italy and is managed by Metropolitana Milanese SpA (MM). The characteristics of such a system can be considered as intermediate between those of classical transmission mains ...

A fuzzy approach for considering uncertainty in transient analysis of pipe networks
Uncertain parameters in the transient analysis of pipe networks lead to uncertain responses. Typical uncertainties are nodal demand, pipe friction coefficient and wave speed, which not only are imprecise in nature but also change significantly over time. Exploiting the fuzzy set theory and a simple scheme of the simulated annealing method, a conceptual model is developed. It can take into ...

Diagnosis of pipe systems by the SLE: first results
In this study, an algorithm is presented for pipe system diagnosis. The algorithm is the Successive Linear Estimator (SLE) previously used in groundwater hydrology to estimate the hydraulic proprieties of soils. The SLE is an iterative cokriging-like technique which provides statistically the best unbiased estimates and quantifies the associated uncertainty. In this paper the algorithm has been ...

3Helium and Duratec Airline System: The Only Way Is Up Case Study
Party City® is an international party supply retailer and one of the largest users of helium in the United States. As a result of helium’s small molecular structure, it is often difficult to efficiently convey and contain as it can diffuse through various piping and fitting materials allowing it to escape into the air. These losses, over time can be very costly. For Party City, once ...

Transient tests for locating and sizing illegal branches in pipe systems
In pipe systems illegal branches can take away remarkable water resources with negative effects from both the economic and technical points of view. Difficulties in pointing out illegal branches by means of steady-state pressure and discharge measurements are mainly due to the fact that, of course, such systems are not active according to a regular time schedule. In this paper the possibility of ...

Policy on Stable Detonation Flame Arresters
Because unstable detonation arresters are designed and tested under the worst case conditions that any arrester is likely to experience for a given gas-group and initial pressure, the physical location of a device within a piping system relative to the ignition source is not subject to any restrictions (except in locations where endurance burning may occur). This is not the case for a stable ...

Acoustically induced vibration: A review of industry best practice
WKC Partner and Noise and Vibration practice leader, Richard Palmer, has recently had an article published in the Institute of Acoustics (IOA) Journal titled ‘Acoustically Induced Vibration: A Review of Industry Best Practice’. This technical paper, which provides the reader with a better understanding of the AIV phenomenon, was published in the IOA Journal in September 2015. The ...

Response of piping system with semi–active variable friction dampers under tri–directional seismic excitation
Seismic loads on piping system due to earthquakes can cause excessive vibrations, which can lead to serious instability resulting in damage or complete failure. In this paper, semi–active variable friction dampers (SAVFDs) have been studied to mitigate seismic response and vibration control of piping system used in the process industries, fossil and fissile fuel power plant. A study is also ...

Dangers of Cavitation in Piping Systems & How to Avoid It
Cavitation is a hot topic for engineers, maintenance professionals and anyone who works with pumping systems—and for good reason. This condition has complicated and difficult-to-identify causes, and its effects can be devastating to equipment, system integrity and overall operations. Preventing cavitation is a full-team effort when it comes to systems operated with centrifugal pumps. It ...

Hydraulic simulation of perforated pipe systems feeding vertical flow constructed wetlands
For successfully operating a vertical flow constructed wetland, the uniform distribution of wastewater on the surface of the soil filter is essential. In research, however, this aspect is often overlooked. This study presents a methodology for assessing discharge uniformity from perforated pipe systems via hydraulic modeling. First, the requirements and conditions for the simulation of ...

Common Mistakes When Installing a Sanitary System
Even the most experienced pump installer can make mistakes when installing a sanitary pump system. To overcome this, we will discuss here important techniques that, if performed during the installation of a sanitary pump, can easily extend the life of the pump. Straight Lines It is always good to install a 4-6 straight inlet tubing into the pumps when installing the sanitary system. This ...

IPEX Piping Systems - Sugar Land, TX Case Study
Founded as a sugar plantation in the mid 1800s, Sugar Land is one of the most affluent and fastest-growing cities in Texas, having grown more than 158% in population over the last decade. With such development, it’s no wonder that the City of Sugar Land needed a better way to provide potable water to support the population while reducing dependence on the existing groundwater withdrawal ...

Pipe Plug with a Huge Bypass Connection
Pipe plugs are an important tool that is used to temporarily seal off sections of a pipe system. They are used in a wide range of industries, including oil and gas, plumbing, and construction. Pipe plugs that feature a large bypass connection, however, offer a number of advantages over other types of pipe plugs. ...

Mosaic Stadium, Regina: Home to the Roughriders and IPEX Case Study
From the beginning the owner was interested in the use of thermoplastic piping systems for drain, waste, and ventilation (DWV), potable water and chilled water lines, but research needed to be done. After looking at price and installation-time comparisons with copper and steel pipe, the most cost-effective choice with the quickest install time was thermoplastic ...

Okatie, South Carolina - SedVac Sediment Removal System installations applications - Case Study
Application The Beaufort-Jasper Water & Sewer Authority required a sludge removal system with a low profile for easy integration below tube settlers. SedVac was chosen based on its ability to be incorporated into the existing basin with minimal infrastructure changes and its successful pilot at the facility – it removed twice as much sludge in half the time and wasted 50% less water ...
