I plant production of spiral welded stainless steel, carbon steel punching center network belong to domestic initiation, straight seam welding stainless steel, carbon steel center specification complete, the network administrator
Material carbon steel, 304 l, 304 l, 304, 304
Specification: small ¦µ 200 * 5.0 mm, and maximum ¦µ 3048 x 25.4 mm pipe length is 6 ~ 30 m commonly, for up to 80 m spiral welded pipe has one side welding and welding by both sides.
Processes: the open-book, roll-up, leveling, butt welding, edge milling, molding, inside outside welding, welding, pipe cutting - test - break - subsequent welding
Dimension: steel pipe outside diameter, wall thickness, ovality, bending, tube end verticality, can according to customer requirements processing production
Spiral pipe features:
pe, can use a narrow billet production of larger diameter welded pipe, you can also use the same width of the billet diameter different welded pipe production. But co***red with the same length of straight seam pipe, weld length increased 30-100%, and the production speed is low. Therefore, relatively small diameter welded pipe are mostly adopts the straight seam welding, large diameter welded pipe for the most part adopts spiral welding.
Spiral pipe is mainly used:
Spiral pipe is mainly used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction, is one of the twenty key product development in our country. For liquid transportation, water supply, water drainage, sewage treatment engineering, transmission mud, sea water. For gas transmission, gas, steam, liquefied petroleum gas. For structure: do the piling pipe, bridge; ***k, road, building structure pipe, Marine piling pipe, etc.
Spiral pipe features:
Straight seam welded pipe production technology is simple, high production efficiency, low cost, rapid development. The strength of the spiral welded pipe is generally higher than straight seam welded pipe, can use a narrow billet production of lar |
