Seam steel pipes and seamless steel pipes are divided according to the form of processing, and seam steel pipes are generally welded.

When issues such as difficult penetration, pile body inclination, pile body torsion, pile dragging down, and difficult extraction occur during steel sheet pile construction, timely measures should be formulated to ensure that the construction progress and quality of the project meet the requirements.

Pressure vessel is a kind of airtight vessel that can withstand pressure. It has an important position and role in many sectors such as industry, civil, military, and many fields of scientific research, especially in the chemical industry and petrochemical industry.

The steel pipe has good ability to resist scratches. Studies have proved that PE80 grade polyethylene pipe has better resistance to SCG and scratch resistance.

A closed vessel that can withstand pressure is a pressure vessel. The pressure vessel has a very wide range of uses, and it has a very important position and function in many fields such as industry, civilian use, and military industry.
