Offshore Structure Pipe

Product Introduction

Offshore Structure Pipe is JCOE pipe. JCOE pipe is the longitudinal seam double-sided submerged arc welded pipe. According to the production process, the longitudinal seam steel pipe can be divided into high frequency longitudinal seam steel pipe and submerged arc welded longitudinal steel pipe. Submerged arc welded straight seam steel pipes include JCOE pipes. Offshore Structure Pipe has simple production process, high production efficiency and low cost.

Advantages

Offshore Structure Pipe is produced on the JCO forming machine. First, half of the pre-bent steel plate is pressed for a "J" shape by multiple stepping and pressing, and then the other half of the steel plate is also bent and pressed on a "C" shape, and finally an open "O" shape is formed . JCOE steel pipes are mainly produced by double-sided submerged arc welding, and then go through multiple processes to meet relevant standards. It can use high current welding with high welding efficiency and good welding quality.

The specification of JCOE PIPE

Straight seam steel pipe fracture phenomenon studies is brittle fracture, and more with the use of component temperature. When the temperature below a certain temperature, the material will be transformed into brittle state, its shock absorption function declined obviously, this phenomenon is known as the cold short, high strength metal materials in low stress brittle fracture in the process, is far from homogeneous isotropic materials organization will have crack, there will be in the inclusions, porosity and other defects, these defects can be as the micro cracks in the material. So, when the design based on component of the operating temperature has the right to select the ductile-brittle transition temperature of the material.

Straight seam steel pipe of high frequency welding is using skin effect and proximity effect of alternating current (ac), steel (strip) after rolling forming, the formation of a cross section of broken circular tube billet, inside the tube billet near the center of induction coil rotating around one or a set of impedance (magnet) and impedance and pipe opening form a electromagnetic induction loop, under the action of skin effect and proximity effect, the pipe opening edges produce powerful and concentrated heat effect, make the weld edge rapidly heated to required after roller extrusion temperature, welding metal molten state to realize the joint between the crystal, after cooling to form a firm butt weld.
