Elbow is mainly used to connect two equal diameter pipes perpendicular to each other at the right angle bend of the pipe, and the different diameter elbow is connected with two different diameters perpendicular to each other so that the vertical pipes can be effectively and reasonably linked together.

Bend refers to the pipe fittings that change the direction of the pipeline in the pipeline system. Elbow by angle, there are 45 °, 90 °, 180 ° three most commonly used, this product is 90 degrees of the female bend, mainly used in plumbing system installation. Bend female in addition to corrosion resistance, but also has excellent mechanical resistance to compression, traction and bending stress.

Everyone knows that fittings are a necessary part when assembling any plumbing system. Having made a high-quality repair once, choosing high-quality parts, you will forget about water supply problems for many years.Despite the fact that the use of cast iron communications is a thing of the past, cast iron fittings are still widely used in pipeline construction. Their enduring popularity is due to the long service life of 60 to 80 years, and the high strength of the material.

In black iron pipe elbow piping system, the elbow is a pipe fitting that changes the direction of the pipeline. According to the angle, there are three most commonly used ones: 45° and 90°180°. In addition, according to engineering needs, it also includes other abnormal angle elbows such as 60°. The elbow materials are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals, and plastics. The ways to connect with the pipe are direct welding (the most common way) flange connection, hot melt connection, electrofusion connection, threaded connection, and socket connection, etc. According to the production process, it can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, etc.

The black pipe crosses fitting is the pipe fitting that controls the fluid or the gas to be transported in all directions. Jianzhi supplied 180 four ways pipe fitting is a kind of equal diameter four-way pipe fitting, which means that the diameter of four outlets is the same. Jianzhi supplied 180 4 way black pipe fittings are made of malleable cast iron and connected by pipe thread. The pressure bearing capacity can reach 2.5MPa, The surface treatment is nature black with a good appearance and performance. Size cover from 1/2`` to 4``. The black pipe cross fitting is one of the most commonly used fittings. We supply them in most buildings, Usually, they need a thicker wall and heavyweight to prevent the damage for 4 directions pipe threading.

Hot dip galvanized grooved pipe fittings adopt internal and external hot-dip galvanizing process, with uniform galvanizing and zinc layer thickness of more than 70μm. After galvanizing, they can be lined with plastic or coated with plastic. It has good anti-corrosion performance and can be used in underground, chemical, seawater and other places.Till now, Jianzhi has about 4,500 employees and more than 350 technical engineers with distributors covering over 100 countries around the world.especially in South Africa.

We offer tongue and groove rigid couplings that are suitable for applications requiring rigidity. While the grooved couplings connection concept has become synonymous with faster and easier installation, not all manufacturers of grooved couplings products are the same. We are unique. The built-in teeth firmly grasp the pipe ends to prevent unwanted flexing. The specific items list will be posted on FM and UL`s websites.

Grooved Flexible Coupling allows for some movement at the joint. That is, Grooved Flexible Couplings are designed to transmit torque while allowing for some radial, axial and angular misalignment.  They can accommodate angular misalignments of up to a few degrees and some parallel misalignments. For general purposes, mining, irrigation and compressed air where 5% or less deflection is required. Services include machinery and pipelines, process pipelines, mining and oilfield pipelines.

Jianzhi Group designs and manufactures grooved pipe fittings, a leading supplier of pipe joint fittings for fire protection systems and water delivery systems in China. Different sizes of 90 degree elbow fittings are available for grooving piping systems. These fittings are UL, FM, CE, ISO certified. In addition to providing quality ductile iron grooved pipe elbows, Jianzhi Group manufactures custom firefighting and water supply solutions, depending on the specific requirements of its clients.

Grooved elbows provide an economical and efficient method of changing direction in grooved piping systems. According to the angle, there are two most commonly used: 45° and 90°.
