FAQ:
1: Q: What's the JCOE pipe ?
A: JCOE is a straight seam double-sided submerged arc welded pipe, straight seam steel pipe according to the production process can be divided into high-frequency straight seam steel pipe and submerged arc welded pipe JCOE steel pipe. Submerged arc welded straight seam steel pipe according to its different molding methods are divided into UOE, RBE, JCOE, LSAW steel pipe. JCOE steel pipe production process is simple, high production efficiency, low cost, rapid development
2: Q: How does the LSAW divided into ?
A: According to the different molding methods can be divided into:
UOE steel pipe: single sheet in the edge of the pre-bending, the U molding, O molding, welding, welding, mechanical cold expansion and other processes.
JCOE steel pipe: that is, according to "J-C-O-E" pre-welding, forming, after welding by cold expansion process
HME steel pipe: by the mandrel rolling method according to "C-C-O" molding, welding after the cold expansion and other processes.
3: Q : How long for the guarantee period ?
A : Guarantee period can delay to 30 days after clients recieved the pipe in the destination port .
Latest News:
JCOE steel pipe straight seam double-sided submerged arc welded pipe advantages:
1)Fully automated
2) Under the submerged arc welding, so its heat exchange and protection performance is relatively strong, welding quality is relatively high;
3) In the submerged arc welding in the arc buried under the welding, so it can use high current, welding efficiency is relatively high.
Our country is carrying out the West-East Gas Pipeline Project, the pipeline is a high-strength steel, this pipe in the factory first pre-made into a section, and then get the site, in the field welding, this pipe produced in the factory welding Of the process is the use of submerged arc welding, submerged arc welding has developed into a double wire submerged arc welding, as well as multi-wire submerged arc welding, the efficiency to further improve.
