Longitudinal pipe equipment classification

Straight joint steel pipe equipment can be divided into high frequency straight joint steel pipe equipment (ERW);Buried arc straight seam steel pipe equipment (LASW);Three roll forming 12 m straight seam steel pipe rolling machine equipment.Here we mainly talk about the latter two, because high-frequency steel pipe can be seen everywhere, the most common is our home heating steel pipe, the original tube is high-frequency straight seam tube.

1-ERW steel pipe equipment

ERW steel pipe equipment production technology mature, high-frequency steel tube is charge according to the principle of electromagnetic induction and communication in the conductor skin effect and proximity effect and eddy current heating effect, make the edge of the weld steel locally heated to a molten state, the squeezing roller, realize the joint between the crystal of butt weld so as to achieve the purpose of the welding seam welding.High frequency steel tube is a kind of induction welding, it does not need welding filler, no welding spatter, narrow welding heat affected zone, beautiful welding shape, good welding mechanical properties and other advantages, so it is widely used in the production of steel tube.

2-Submerged arc welding steel pipe equipment

Submerged arc welded straight seam steel tubes are divided into UOE, RBE and JCOE steel tubes according to their different forming methods.The following describes the most common high frequency straight joint steel pipe and submerged arc welding straight joint steel pipe forming process.Forming: on the JCO molding machine, first of all, half of the pre-bent steel plate is pressed into a "J" shape after several steps, and then the other half of the steel plate is also bent into a "C" shape, finally forming an open "O" shape.Submerged arc welding straight seam steel pipe equipment production range: 325mm-1520mm, production wall thickness from 7.5mm-100mm, production process known as JCOE.Production materials are not limited.

3- three roller forming equipment

As shown in the figure below, the three-roller forming equipment is a 12-meter large straight seam steel pipe forming equipment. It is a newly developed production technology with flexible production performance and no longer limited by the quantity. It can be produced in a timely manner if the quantity is large or small.The biggest advantage of the three-roller forming equipment is not only flexible production, it produces straight seam steel pipe products in physical size, can be said to be close to perfect.However, its production range is limited. The three-roll forming equipment can produce a maximum of 3500mm, a minimum of 700mm, a maximum of 30mm and a maximum of 12m.It can be seen that the main production of three roller forming equipment or large diameter thin-wall steel pipe.
