China LWN Flange Manufacturer, Supplier, Factory

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.

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.

As the professional manufacturer, we would like to provide you shuangneng Blind Flange.And we will offer you the best after-sale service and timely delivery.A blind flange is a type of flange without a hole in the center, which is designed to seal off the end of a pipeline or used to remove debris from a pipeline during maintenance. The Flange usually made of high quality steel, such as carbon steel, alloy steel or stainless steel, to meet the needs of different working environments.

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.

SN Valve is a leading China threaded cross manufacturer. Threaded tee is an important pipe fitting that connects four pipes together by means of a threaded connection to realise the diversion or merging of fluids. It is widely used in industrial fields such as petroleum, chemical, natural gas, water treatment and heating, as well as in building and civil piping systems for changing piping direction, branching piping or realising special connections.

SN Valve is a leading China threaded 45 degrees elbow manufacturer. Threaded 45 degrees elbow bends the pipe in 45-degree direction by means of threaded connection, so as to realise the change of pipe direction. It is widely used in industrial fields such as petroleum, chemical, natural gas, water treatment and heating, as well as in building and civil piping system.
