Cold drawn cylinder pipe

 

Cylinder pipe are mainly applied in hydraulic driving equipment (including hydraulic and pneumatic steel cylinder, hydraulic support, oil-well pumping barrel, and etc.) used for the manufacturing of vehicle, engineering machinery, lifting and transportation machinery and other machinery. Liquid steel has high purity, excellent geometrical dimension and good performance for processing.

High Chromium Cast Iron Bimetal Cladding Pipe

High Chromium Cast Iron Bimetal Cladding Pipe, High Chromium Cast Iron pipe, Bimetal Cladding Pipe We are manufacturer of High Chromium Cast Iron Bimetal Cladding Pipe and supply high quality High Chromium Cast Iron Bimetal Cladding Pipe in both large and small quantities worldwide and offer you the best prices in the market. These Steel-high chromium cast iron bimetal cladding pipe is a new type of abrasion proof piping developed by our company. Outer of straight pipe is common steel pepe, cladding realized by forming high chromium lining via centrifugal forming technique. Outer of bend uses hot-bending bend and lining is cast with high-chromium cast iron. Compared with traditional wear-resistant alloy cast iron, wear-resistant alloy cast steel, general cladding steel pipe and cast stone pipe. 1. Good wear-resistance, giving full play to wear-resistance of high chromium cast iron. 2. Withstanding high pressure: It can be used for any pressure rating. Close bonding of outer and lining ...

15CrMoG seampless PMI test

The range of 15CrMoG pipe sizes that may be examined by each method shall be subjected to the limitations in the scope of the respective practice. For high-pressure boiler (working pressure 9.8MPa or more generally, the working temperature between 450℃-650℃) of heating surface tubes, header, economizer, superheater, reheater and so on. 15CrMoG Seamless Tubes for High Pressure Boiler description Standard: GB 5310 Relative grades: 20G, 20MnG, 15MoG, 15CrMoG, 12Cr2MoG, 12Cr1MoVG. After consultation, can also supply other grades of steel. 15CrMoG Alloy steel pipe is a seamless steel tube, its performance is much higher than the general seamless steel pipe, because the inside of this tube contains CR more, its alloy steel tube high temperature, low-temperature, corrosion resistance of other seamless steel tubes, so the alloy tube in the petroleum, chemical, electric power, boiler and other industries are more widely used. 15CrMoG Alloy steel pipe is a seamless steel tube, its performance is...
