Features of API Tubing Pipes
Through advanced manufacturing processes such as cold drawing or cold rolling, Tubing Pipes can achieve highly precise outer and inner diameter dimensions as well as strictly controlled wall thickness tolerances.
With good surface quality and a smooth surface, it is conducive to the smooth flow of fluids, reduces frictional resistance and pressure loss, and also helps to improve the corrosion resistance of the pipes.
No matter what material the Tubing Pipes are made of, they all possess a certain combination of strength and toughness. In terms of withstanding internal pressure, they can meet the requirements of different pressure levels.
They have strong workability. It is easy to carry out various subsequent processing operations, such as cutting, bending, welding, thread processing, etc. This enables them to be flexibly customized and modified according to specific installation requirements and system designs.
