spiral fittings Spiral steel pipe edge milling machine milling groove Angle is accurate, from the beginning to the end unchanged, can avoid forming seam "tight and loose" or "tight and loose" and other defects;Spiral steel pipe edge milling machine milling out of the steel belt edge and groove surface roughness is good, reduce the wrong side, burn through, voltage and current fluctuations of defects;Spiral steel pipe edge milling machine can eliminate part of the crescent bending, smooth through the joint;Milling out welding groove on both sides of the steel belt at the same time ensures the width of the steel belt unchanged, which is conducive to the stability of the forming quality of the steel belt.
SSAW steel pipe
Q235A, Q235B, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb
Generally smooth, bright
Export standard packing or according to customers’ requirement
Within10-15 workdays,25-30days when the quantity beyond 1000tons
Spiral Fittings after cutting into a single steel tube, the first three steel tubes in each batch shall be subject to a strict first inspection system to check the mechanical properties, Spiral Fittings chemical composition, melting state, surface quality of the steel tube and nondestructive inspection to ensure that the pipe manufacturing process is qualified before it can be formally put into production.
the Spiral Fittings part marked by continuous acoustic inspection on the weld shall be subject to manual ultrasonic and X-ray reexamination. If there is any defect, it shall be repaired and then Spiral Fittings subjected to nondestructive inspection again until the defect is confirmed to be eliminated.
the Spiral Fittings pipe where the butt weld of the strip and the t-joint intersecting the spiral weld are located shall be inspected by X-ray television or film.Spiral Fittings each steel tube is hydrostatic tested, and the pressure is sealed radially.The test pressure and time are strictly controlled by the microcomputer testing device for water pressure of steel tube.Test Spiral Fittings parameters are automatically printed and recorded.Spiral Fittings the pipe end is machined to ensure the verticality of the end face, bevel Spiral Fittings Angle and blunt edge are accurately controlled.
