Find a huge selection of threaded 90 degree elbow from China at SN Valve. Threaded 90 degree elbow connects with pipes or other fittings through its internal threads to achieve the turn of pipes in 90 degree direction. This kind of elbow is widely used in various industrial, construction and civil piping systems, such as petroleum, chemical, natural gas, water treatment and heating.

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.

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.

Long Weld Neck Flange (LWN) is an extended form of butt welded flange with a neck, whose neck height is significantly higher than that of ordinary butt welded flanges. The neck is usually designed in a straight cylindrical shape, and the height is adjusted according to the nominal diameter (DN): when DN ≤ 100, the neck height is 229mm, and when DN>100, it is 305mm. The thickness of the neck wall gradually transitions to the thickness of the pipe wall, effectively improving the stress distribution, enhancing the rigidity and bearing capacity of the flange, making it suitable for working conditions with high pressure, high temperature and frequent temperature changes.

Loose flange is a type of flange connection that is characterized by a certain degree of mobility or removability of the connection between the flange and the pipe or equipment. This type of connection allows the flange to be easily Loose flange is widely used in a variety of industrial fields, especially in situations that require frequent disassembly and replacement of equipment. It allows the pipeline or equipment to be moved and adjusted to a certain extent without being restricted by the flange, thus improving the flexibility and adaptability of the system.

SN Valve is a leading China porous plate flange manufacturer. Porous filter plate flange, i.e. a component that combines a porous filter plate with a flange. This kind of component is usually used in occasions where filtration and connection are required, such as filtration devices in piping systems, separation equipment for liquids or gases, and so on. The porous filter plate flange is connected to other pipelines or equipment through flange connection, and at the same time, the filtration function of the porous filter plate is utilized to realize the filtration and separation of liquids, gases or solid particles.
