China 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.

The rubber flexible joint flange is a part used to connect pipes and equipment together. It consists of two parts: a flexible rubber joint and a flange. Rubber flexible joints are usually made of rubber materials and have good elasticity and sealing properties. In addition, they can also absorb the vibration and displacement of the pipeline to protect the pipeline from damage. On the other hand, a flange is a metal part used to connect pipes or equipment, with one or more protruding edges (i.e., flange faces) for bolting with other flanges or parts.

A butt welding 90 degrees lr elbow elbow is a pipe fitting that is connected to a pipe by welding with a 90-degree bending angle and a long bending radius, often referred to as a long radius (LR) elbow. The design of this elbow allows for a smoother flow of fluid through the pipe, reducing flow resistance and pressure loss.

As the professional manufacturer, SN Valve would like to provide you high quality socket welded flange. Socket weld flange is a flange in which the end of the pipe is inserted into the step of the flange ring and welded at the end and outside of the pipe. It usually consists of flange body, bolt holes, sealing surface and other parts, and its structural form has two kinds of necked and non-necked. Necked socket weld flanges have good rigidity, small welding deformation and better sealing, so they are more common in practical applications.

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.

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.
