Firefighting pipes generally use galvanized pipes. When the pipe diameter is required to be greater than 100mm, seamless pipes should be selected.

To put it simply, low-alloy seamless pipe is actually a stainless steel plate made of aluminum alloy. It is a long steel plate with a hollow cross-section and no seams around it.

Seamless steel pipes are made of a whole round steel perforated. Steel pipes with no welds on the surface are called seamless steel pipes.

The material selection and construction requirements of tunnel seamless steel pipes are important links in ensuring the stability and safety of tunnel projects.

Fluid seamless pipe is a pipe used to transport fluid. Its inner wall is smooth and seamless, which can ensure smooth flow of fluid.

The quality hazards of seamless steel pipes cannot be ignored.
