buy stainless steel seamless pipe from china manufacturer

application of stainless steel seamless pipe:

Stainless steel seamless pipe more economic and practical.The process of this product determines its limited performance.Its processing costs will rise substantially;The thicker the wall of this product, its detection and shaping must be handled offline, so it shows its advantages in high pressure, high strength and mechanical structure materials.Stainless steel seamless tube is a hollow section, no seams around the strip steel, and the appearance is not easy to remove and pitting, black spots, generally low precision seamless steel pipe: low surface brightness, uneven thickness, tube length cost is high.The thicker the walls, the thinner.

Features of the stainless steel seamless pipe :

First, the thicker the wall of this product, the more economic and practical it will be. The thinner the wall, the higher the processing cost will be.

Second, decide the limits of its performance of the product process, generally low precision seamless steel pipe: low surface brightness, uneven thickness, tube length cost is high, and the appearance is not easy to remove and pitting, black spots inside;

Third, its detection and plastic surgery must be offline.Therefore, it shows its advantages in high pressure, high strength and material for mechanical structure.

Vacuum, stainless steel tube seamless tube specifications and appearance quality

A. According to the rules of gb1975-94 stainless steel seamless steel pipe, the general length of the steel pipe (indefinite scale) is 1.5-10m, and the hot-extruded steel pipe is equal to and greater than 1m.Cold drawn (rolled) steel tube wall thickness of 0.5 ~ 1.0mm, 1.0 ~ 7m;Wall thickness greater than 1.0mm, 1.5 ~ 8m.

B. There are 45 types of hot-rolled (hot-extruded) steel tubes with a diameter of 54 ~ 480mm.There are 36 kinds of wall thickness from 4.5 to 45mm.There are 65 kinds of cold-drawn (rolled) steel tubes with diameters of 6 ~ 200mm.There are 39 kinds of wall thickness ranging from 0.5 ~ 21mm.

C, steel tube exterior appearance can not have crack, folded, crack, crack, rolling, delamination and scarring shortcomings exist, these shortcomings should be rooted out to (for machining tube), after rooting out beyond the negative error may not make the wall thickness and diameter.Other minor appearance flaws that do not exceed the tolerance for negative errors are not eliminated.

D. the straight path allows depth.Hot-rolled and hot-extruded steel tube with diameter less than and equal to 140mm shall not be greater than 5% of the nominal wall thickness, and the maximum depth shall not be greater than 0.5mm.Cold drawn (rolled) steel pipe shall not be more than 4% of nominal wall thickness, and the maximum depth shall not be greater than 0.3mm.

E. cut the ends of the steel tube at right angles and remove the burrs
