is a type of welded pipe manufactured using an electrofusion welding process. This process first processes flat plates or steel coils into pipes, then welds the joints using a high-frequency current.
. It is a type of steel pipe manufactured by heating the edges of a steel plate to a molten state using an electric arc, then fusing them under pressure to form a weld.
What is the difference between ERW steel pipe and ASTM A672 EFW steel pipe?
uses resistance heating to fuse the edges, while ASTM A672 EFW (electrofusion welding) uses an electric arc to melt the steel, typically using filler metal to form the weld.
Is ASTM A672 EFW steel pipe a seamless steel pipe?
ASTM A672 EFW steel pipe is not a seamless steel pipe; it is a welded steel pipe made by electrofusion welding steel plates. This welding process differs from seamless steel pipes, which are made from a single piece of metal without welds or seams.
What are the main applications of ASTM A672 electrofusion welded (EFW) steel pipe?
ASTM A672 electrofusion welded steel pipe,
Oil and Gas: Used for constructing pipelines to transport oil and natural gas.
Water Supply: These pipes are suitable for water supply systems, ensuring a stable water supply.
Construction: These pipes are often used for structural support in building construction projects.
Chemicals: These pipes are ideal for pipelines and other equipment used to transport chemicals or corrosive substances.
