Knowledge of ERW line pipe

With the rapid growth of the economy and increasing energy demands, the production of Electric Resistance Welded (ERW) line pipes has advanced significantly. This article focuses on the manufacturing process of ERW pipes, highlighting the effects of circumferential residual stress on product quality. The forming process is divided into two main stages: deformation and distortion reduction, where both inner and outer layers experience different stress states. Common issues such as uneven deformation and the need for effective residual stress analysis are discussed, along with the critical role of sizing and hydrostatic testing in maintaining high-quality stan

Concentric Reducers VS Eccentric Reducers

In Concentric Reducer the reduction of the pipe size is achieved by decreasing the diameter of the fitting at a constant rate over a specified length, maintaining symmetry around the fitting. Concentric Reducers are used to join pipe or tube sections of different diameters on the same axis. They provide an in-line conical transition between pressurized pipes of differing diameters. Thus, concentric reducers connect pipes of unequal size but have a common centerline. The same fitting can be used in reverse as an concentric expander.

The difference between elbow and tee

Both elbows and tees are used to change the direction of a pipe, but elbows are used to connect at pipe bends, while tees are used to connect at main pipe branches.

Precautions for the Use of Best Stainless Steel Elbows

When installing, the best stainless steel elbow can be installed directly on the pipeline according to the connection method, or it can be installed according to the location of use. Under normal circumstances, it can be installed anywhere in the pipeline, but it needs to be sealed to prevent flushing and affect the pipeline. normal operation.
