2-14 inch low-temperature resistant telescopic steel union

Telescopic steel union is a device used for pipeline connection, which is an upgraded product of pneumatic tire union. The design and manufacturing of telescopic steel unions consider various materials and specifications to adapt to different working environments and medium requirements. The working medium of this connection device includes clean water and drilling fluid (containing oil, acid and alkali), with a temperature range of 0 ° C to 80 ° C and a working environment temperature range of -40 ° C to 55 ° C. The materials of the telescopic steel union include but are not limited to stainless steel, 20, 20G, A234WPB, A105, Q235, 16Mn, 0Cr18Ni9, 0Cr18Ni10Ti, 00Cr17Ni14Mo2, 00Cr17Ni12Mo2, 304, 304L, 316, 316L, 321 and other materials. ?

The design features of the telescopic steel union include variable diameter joints, which are used to achieve conversion connections of different diameters and thread specifications in pipelines. The variable diameter joint is forged from high-strength alloy steel and precision machined by CNC machine tools, ensuring simple and reliable connection. The application range of telescopic steel union is wide, including but not limited to oilfield drilling fluid solid control systems, mud tanks and other equipment, used for cementing, fracturing, acidification, testing and plugging of well killing pipelines, and can also be used for non pressure sealed connections. ?
