Straight Seam Steel Pipe

SPECIFICATIONS

Straight Seam Steel Pipe

The straight seam steel pipe is the steel pipe which is parallel to the longitudinal seam. Usually divided into metric welded steel pipe, welded thin-walled tube, transformer cooling tubing and so on. Straight seam steel welded pipe have the advantage of production process simple, high production efficiency, low cost, rapid development. The strength of spiral welded pipe is generally higher than that of straight seam welded pipe, it can produce welded pipe with larger pipe diameter with narrower billet, and can produce welded pipe with different pipe diameter with same width. However, the weld length increases 30~100% and the production speed is lower compared with the straight seam tube of the same length.

Production process
Straight seam steel pipe according to the production process can be divided into high-frequency straight seam pipe and submerged arc welded straight seam pipe. The submerged arc welded straight seam steel pipe is divided into Uoe, RBE, Jcoe steel pipe and so on according to its different molding mode.
Processing method
The main processing methods of straight seam steel pipe are:
1. Forged STEEL: A pressure-processing method that uses the reciprocating impact of a hammer or pressure of a press to change the billet to the shape and size we need.
2. Extrusion: It is the steel to put the metal in a sealed squeeze, one end of pressure, so that the metal from the specified mold hole extrusion and get the same shape and size of the finished product processing method, more used for the production of non-ferrous metal materials.
3. Rolling: The steel metal blanks through a pair of rotating rollers of the gap (various shapes), due to the roll compression so that the material section is reduced, the length of the increase in the pressure processing method.
4. Pull steel: Is the rolling of metal blanks (type, pipe, products, etc.) through the mold broaches to reduce the length of the increase in the processing method is mostly for cold processing.
Use
Straight Seam Steel Pipe
Straight seam steel pipe is mainly used in water engineering, petrochemical industry, Chemical industry, power industry, agricultural irrigation, urban construction.
For liquid transportation: water supply, drainage.
For gas delivery: gas, steam, liquefied petroleum gas.
Used for construction: piling Pipe, bridge, Wharf, road, building structure pipe, etc.
