The standard and application of stainless steel seamless pipe and welded pipe

Stainless steel seamless pipe is a hollow cross-section and the surrounding no seam of the long stainless steel pipe. Stainless steel welded pipe is made of stainless steel plate or strip by crimping and then made of a steel pipe. Here to introduce the two under the standard steel.   The standard of stainless steel seamless pipe   Since the characteristics of seamless steel hollow section, a large number of pipes are used as the transport fluid, such as transportation of oil, gas, coal gas, water and some solid materials, pipes and the like. Stainless steel seamless pipe compared to […]

The Differences between Socket Welding and Butt Welding

Socket Weld (SW) fittings A socket weld fittings involves two different sized pieces of pipe. The smaller one is inside the larger pipe. The  weld is completely around the outside circumference of the larger pipe. Butt weld (BW) fittings A butt weld fittings is two pieces of materials butted against each other and welded. Several different methods  exist for beveling the two pieces for good weld penetration. Both flat stock and pipe or tubing can be  butt welded. Generally, the weld is ground flush with the material surface. Price Normally, the price of Socket weld fittings is higher than Butt weld fittings in similar size. But the extra cost of butt weld […]

Stainless steel pipe bend

Process characteristics of stainless steel pipe bend   If the processing technology of stainless steel pipe is not handled properly, it is possible to relax and damage the metal structure. This kind of damage is a kind of fine grain boundary crack, which will affect the mechanical properties and service life of the tube to a certain extent. The heating range of stainless steel pipe bend’s pipe is very small, and the temperature inside and outside the pipe wall is also different. Chromium is the most basic element of stainless steel stamping pipe bend. When the chromium content in stainless […]

What are the processing methods of the tube sheet

The tube sheet is refers to in the circular steel plate to drill the hole which is slightly bigger than the outer diameter of the pipe, passes through the tube to weld the fixed one kind of fitting. Tube plate for tubular heat exchanger, boiler, pressure vessel, steam turbine, large central air-conditioning industry. The material of the tube plate will be selected according to the bad environment. The detection of the tube sheet includes the hole position, the aperture tolerance, the inner hole finish, the burr, etc.. For three or four kinds of pressure container tube sheet need high accuracy, […]

The production process of welded stainless steel pipe

Welded stainless steel pipe production, the main industry is the nominal pipe diameter of more than DN700 in the production pipeline. Slotted pipe not only includes the straight pipe, and comprises a spiral weld pipe. The main specifications and production of welded stainless steel pipe with nominal diameter 700mm multiplied by the thickness of 10mm (denoted as 711×10), nominal pipe diameter 800mm multiplied by the thickness of 12mm (denoted as 813×12), multiplied by the nominal pipe diameter 900mm 14mm thick steel plate (denoted as 914×14), multiplied by the nominal diameter 1000mm 18mm thick (expressed as 1016 x18) and other product […]
