China Industrial Pipe Fittings Manufacturer, Supplier, Factory

SN Valve is a leading China butt welding 180 degrees lr return manufacturer. Butt welding 180 degrees lr return elbows are connected to the pipeline by welding and have a 180-degree bending angle and a long bending radius, hence the name long radius (LR) return elbow. The design of this elbow allows for smoother fluid flow through the pipeline, reducing flow resistance and pressure loss, while providing more space to accommodate piping layout and installation.

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.

Find a huge selection of stainless steel tube sheet from China at SN Valve. Stainless Steel Tube Sheet is a structural material made of stainless steel in the form of a combination of tubes and sheets. It is an alloy with excellent corrosion resistance. It has a chromium content of at least 10.5 per cent and a carbon content of no more than 1.2 per cent, with possible additions of nickel, molybdenum, titanium and other elements to enhance performance.
Corrosion resistance: It is resistant to weak corrosive media such as air, steam and water as well as chemical media such as acids, alkalis and salts.
High strength: stainless steel has high tensile and yield strength, which can meet the needs of various structural applications.
Excellent processing performance: easy to cut, bend, weld and other processing operations, easy to make a variety of shapes and sizes of pipe and plate structure.

High quality high pressure butt welding flange is offered by China manufacturer SN Valve. High-pressure butt-welding flanges are the type of flanges that are butt-welded to the pipeline through the long neck, and their structural features include the long neck, the flange face and the welding bevel. The design of the long neck part makes the connection between the flange and the pipe stronger and can withstand higher pressure and temperature. The flange face is used to make contact with the sealing gasket to form an effective seal. The design of the welding groove is to facilitate the welding of the flange and the pipeline.

Find a huge selection of Plate (PL) Flanges from China at SN Valve. Plate flat welding flange is a kind of flange cut from steel plate with a full flat flange face and a round bore in the center for connection with pipes or other flanges. The connection is usually made by flat welding, i.e., the flange is aligned with the protruding part of the pipe or equipment and then firmly connected by welding.
