Stainless Steel Seamless Pipe is a hollow steel bar, a large number of pipes used for conveying fluids, such as oil, gas, water, gas, steam,heat exchanger,mechinical machine. In addition, engaging in bending, torsional strength of the same, lighter, and they are also widely used in the manufacture of mechanical parts and engineering structures. Also used in producing all kinds of conventional weapons, the barrel, artillery shells and so on.

The classification of stainless steel seamless pipe Stainless steel tubing at seam pipe have two broad categories. By the cross sectional shape can be divided into special-shaped pipe and tubes, widely used are circular steel tube, but there are also a number of square, rectangular, semi-circular, hexagon, equilateral triangle, octagon and special-shaped steel tub.

For the steel tube under fluid pressure hydraulic pressure test should be conducted to test its capabilities and the quality of voltage, in the provisions does not happen under the pressure of leakage, wet or expansion of qualified, some even based on standard steel pipe or crimping demand-side requirements test, flaring test, flattening test.

Seamless stainless steel tube: seamless steel pipe or solid steel ingot are used by the perforated tube made of capillary, and then by the hot-rolled, cold-rolled or cold call made. The specifications of seamless steel pipe with outer diameter * wall thickness of a few millimeters express. Hours of hot-rolled and cold-rolled seamless steel pipe types of steel pipe.
