Socket Welding 90 Degrees Elbow

SN Valve is a leading China socket welding 90 degrees elbow manufacturer. Socket welding 90 degrees elbow plays a role in pipeline connection to change the direction of fluid transmission, so that the fluid can be turned at right angles. It is designed with a socket at one end, and the other end is matched with the outside diameter of the pipeline, for insertion into the main pipe for welding. Socket welding 90 degree elbow is mainly used in small diameter, high pressure piping system, especially in the need to strictly control the risk of leakage and higher strength requirements of the occasion, such as petroleum, chemical, electric power and other industries in the pressure piping system.

Soft Joint Flange

High quality soft joint flange is offered by China manufacturer SN Valve. Soft joint flange usually consists of a pair of flanges, a soft joint (e.g. made of rubber, plastic or other elastic materials) and a number of bolts and nuts. The soft joint sits between the two flanges and acts as a seal and cushion. This type of flange connection through the bolts and nuts to the two flanges closely clamped together, and use the elastic deformation of the soft joint to compensate for the piping system displacement, vibration and temperature changes and other factors caused by the stress.

Threaded Tee

Find a huge selection of threaded tee from China at SN Valve. A threaded tee is a fitting with three openings, one of which serves as the main pipe and the other two as branch pipes. By means of threaded connection, the threaded tee can connect three pipes together to achieve 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.

Welding Neck Flange

Chinese manufacturer SN Valve offers high-quality Welding Neck Flange. A butt-weld flange is a flange with a longer neck that usually matches the outer diameter of the pipe so that it can be welded to the pipe. This flange structural design improves the rigidity and strength of the flange, while improving the sealing performance of the connection. Butt-weld flanges are usually made of high-quality forged steel materials and can withstand high-pressure and high-temperature working environments.

Socket Welding Coupling

SN Valve is a leading China socket welding coupling manufacturer. Socket weld pipe hoop is a kind of pipe fitting that connects two pipes together by socket welding. Its structure is characterised by the design of a socket at one end, which can be inserted into the end of another pipe and welded to make the two close together. Socket welded pipe hoop is usually machined from round steel or ingot after die forging, with key dimensions such as socket hole diameter, socket hole wall thickness and socket hole depth.

Do you know why the gasket on both sides of the tube sheet must be made of the same material?
The tube sheet is on both sides of flange fastening bolts, they are the same bolts, and the pressure on the gasket on both sides of the tube sheet is the same, and they are under force at same time.
What Is a Plate Flange?
In industrial piping systems, structural connections, and pressure equipment, few components are as critical—and as misunderstood—as the plate flange. Whether you are designing a new pipeline, upgrading an existing system, or sourcing components for heavy-duty industrial use, understanding plate flanges can directly impact safety, performance, and long-term cost efficiency.

Preventing Chloride Stress Corrosion: Why 316L Stainless Steel Flanges Outperform Carbon Steel in Coastal Plants
In 2023, Wenzhou Shuangneng Valve Co., Ltd. helped an Indonesian power plant replace carbon steel flanges with 316L stainless steel, reducing chloride-induced failures by 40% within 12 months. Coastal salt spray and humidity accelerated corrosion in carbon steel, while 316L’s molybdenum-rich alloy prevented stress cracking.
