China Dual Phase Steel Flange Manufacturer, Supplier, Factory

SN Valve is reputed Paddle Blank and Spacer Manufacturers in CHINA, Our offered Spade and Spacers are normally referred to as Line Blinds, has the similar function as a Spectacle Blind . The Spade or Spacer is fitted in the line between two flanges and is bolted in place. The Spade Ring Spacer is used when the line is required open and the Paddle Blind or Spade is installed when the line is required blocked or closed. To change it from open to closed, only half the bolts need to be removed and the Paddle Spacer is swapped over. The removed bolts are then installed and tightened. The handle from the pipe and provides an indicator of a Spade or Ring Spacer is installed.

Threaded flanges are flanges with internal or external threads that are connected by screwing the threads on the flange to the threads on the pipe or equipment against each other. This type of flange is usually used in low-pressure and low-temperature operating environments because of its relatively low connection strength, but easy installation and removal.

Stainless steel pipe caps are essential fittings designed to seal the ends of pipes, preventing leakage, contamination, and mechanical damage. Crafted from premium 304, 316, or 316L stainless steel, these caps deliver exceptional corrosion resistance, high-temperature tolerance (-196°C to 800°C), and pressure durability, making them ideal for demanding industries like oil and gas, chemical processing, pharmaceuticals, food production, and marine engineering.
