Cage Filters our factory production of stainless steel, carbon steel punching spiral welding center network management are the domestic origination, the straight seam welding stainless steel, carbon steel center network management are complete in specifications
Material of carbon steel, 304, 304 l, 316, 316 l
Specification: small ¦µ 200 x 5.0 mm, the biggest ¦µ 3048 x 25.4 mm tube length is commonly 6 ~ 30 m, the longest 80 m spiral welded pipe has one side welding and welding by both sides.
Technological process: uncoiling - 1 - leveling - butt welding - edge milling - forming -- -- -- in welding the weld pipe cutting - crevasse - subsequent welding - test
External dimensions: steel pipe diameter, wall thickness, ovality, bending, pipe end verticality, can according to the customer request processing production
USES: mainly used in oil, natural gas transmission pipeline.
Spiral pipe features: straight seam welding tube production process simple, high production efficiency, low cost, rapid development. The strength of the spiral welded pipe is usually better than straight seam welding pipe is high, can use a narrow billet production of larger diameter welded pipe, still can use the same width of the billet production pipe diameter different welded pipe. But with the same length straight seam pipe, co***red to weld length increases 30 ~ 100%, and the production speed is low. Therefore, a small-bore tube welding mostly adopts the straight seam welding, large diameter welded pipe is mostly using spiral welded. |
