As the main force of long-distance pipelines, what is the difference between oil pipelines and gas pipelines? We mainly use common crude oil steel pipes for oil pipelines.1. Different power sources: energy is also required, but crude oil steel pipes and natural gas steel pipes have different power s
Read MoreFirst: welding processIn terms of the welding process, the welding method of spiral steel pipe and straight seam steel pipe is the same, but straight seam steel pipe will inevitably have a lot of T-shaped welds, so the probability of welding defects is also greatly increased, and the welding residue
Read MoreStainless steel pipe is a strong, tough metal with high corrosion protection, high-temperature resistance and the ability to be sterilized. It has high workability and can be manufactured to tight tolerances and welded. These alloys are the most commonly used stainless steel alloys and are a cost-ef
