. It is a process that uses electric current to heat metal parts until they melt and fuse together.
The main visual difference lies in the weld direction: the weld seam of a straight seam welded pipe is parallel to the length of the pipe, while the weld seam of a spiral welded pipe is spiral-shaped along the circumference.
What is the most common delivery condition for Q235 ERW straight seam welded pipes?
Q235 ERW straight seam welded pipe is flat end, fixed length (unless otherwise specified, usually black (uncoated)).
is steel coil, usually carbon steel. Other types of steel, such as stainless steel and alloy steel, are also used for applications requiring corrosion resistance or higher strength. The steel coil is cold-bent into a cylinder and then resistance welded.
Why is galvanized Q235 ERW pipe commonly used outdoors?
Q235 ERW pipe is commonly used outdoors because of its high strength and protective zinc coating, which prevents rust and corrosion from exposure to the natural environment. This corrosion resistance, combined with its high strength, durability, and cost-effectiveness, makes it ideal for applications such as outdoor construction, scaffolding, and fencing.
