Bottom price for Longitudinal Pipe Steel round longitudinal welded pipe export to Brazil Factory

Straight seam pipe generally high-frequency welding, high frequency welding is a kind of induction welding (or pressure contact welding), it does not need to weld filler, weld spatter, welding heat affected zone is narrow, beautiful welding molding, welding, the advantages of good mechanical performance, so in the production of steel by wide application. According to the principle of electromagnetic induction and the exchange charge in the conductor tends to skin effect and proximity effect and eddy current heat effect, the edge weld steel local heating to a molten state, through the roller extrusion, the butt weld the intergranular bonding, so as to achieve the purpose of seam welding, cooling after the formation of a strong straight seam welding.

Steel Round Longitudinal Welded Pipe


Classification by application

Roller tube: for the belt conveyor roller welding steel pipe, generally with Q215, Q235A, B steel and 20 steel manufacturing, diameter 63.5-219.0mm. On the tube bending, end face to be vertical, and the center line of ovality has certain requirements, the general pressure and flattening test.
Transformer for manufacturing of transformer radiator tube and other heat exchangers, made of ordinary carbon steel, flattening, expanding export, bending, the hydraulic test tube. Steel pipe to be fixed or double the length of delivery, the bending of the steel pipe has a certain degree of requirements.


Shaped tube: by ordinary carbon node structure steel and 16Mn steel welded square tube, rectangular tube, tube cap, empty plastic steel windows and doors with steel pipe, mainly used as agricultural machinery parts, steel window and door etc..
Welded thin-walled tube: mainly used to make furniture, toys, lamps, etc.. In recent years, with the production of stainless steel tube is widely used, furniture, decoration, fences etc..

Spiral welded pipe: is low carbon structural carbon steel or low alloy steel strip steel and according to the certain helix angle (called forming angle) rolled into a tube, then the tube seam welded together made, it can narrow strip steel production of large diameter steel pipes. Spiral welded pipe is mainly used for oil and natural gas transmission pipeline, the specification of outer diameter * wall thickness. Spiral welded pipe has one side welding and double side welding, welded pipe should ensure that the hydraulic pressure test, the tensile strength of the welded joint and the cold bending properties should be consistent with the provisions.
