Stainless Steel Seamless Pipe | SS SMLS Pipe

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, 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 tube.

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 steel pipe types of seamless steel pipe.

General points of hot-rolled seamless steel pipe steel pipe, low, medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipe, oil cracking pipe, geology, such as steel pipe and other pipe.

Cold-rolled (allocated) Subject to sub-ordinary steel pipe seamless steel pipe, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipe, petroleum cracking pipes, other steel pipes, but also including thin-walled carbon steel pipe, alloy thin-walled steel tube,stainless thin-walled steel tube, shaped steel tube.

Hot-rolled seamless pipe outer diameter generally greater than 32mm, wall thickness 2.5-75mm, Department of cold-rolled Stainless steel pipe diameter can go to 6mm, wall thickness can be 0.25mm, outer diameter thin-walled tube can be less than 5mm thickness 0.25mm , cold-rolled than the size of hot-rolled and high accuracy. stainless steel tube with the social and economic development, its application has also been widespread popularity. In various fields is bound to bring about a new change

Welded Large Diameter Stainless Steel Pipe

Welded pipe is made from stainless steel strip or plate, through rollers to form desired shape, and welding longitudinally edges using TIG, EFW, EFW and other welding technologies, for large diameter pipe, double welding may be required.

Seamless Large Diameter Stainless Steel Pipe

Seamless pipe is manufactured from hollow billets, through cold finished and heat treatment process to obtain desired pipe dimension, and with manufacturing process together, seamless pipe technology can achieve very heavy wall pipe.
