Straight seam welded pipe, steel pipe made of hot or cold rolled steel plate or steel strip coil welding, straight seam welded pipe on the welding equipment are called straight seam welded pipe. (Because the welding of the steel pipe is a straight line, so named). Among them, according to different uses, and different post-production processes, (can be roughly divided into scaffolding pipe, fluid pipe, wire sleeve, bracket pipe, guardrail pipe, etc.).

Product Specification
Ingredients/Data

1. Classification of welding methods

According to different welding methods, it can be divided into arc welding pipe, high frequency or low frequency resistance welding pipe, gas welding pipe, furnace welding pipe, Bondi pipe and so on.

Electric welded steel pipe: used in oil drilling and machinery manufacturing.

Furnace welded pipe: can be used as water gas pipe, etc., large mouth straight seam welded pipe for high pressure oil and gas transmission; Spiral welded pipe is used for oil and gas conveying, pipe pile, bridge pier, etc.

2. Classification by weld shape

Can be divided into straight seam welded pipe and spiral welded pipe
