API 6A Weld Neck Flanges are pipe flanges attach by welding the pipes to the neck of the flanges. This transfers stress from the flange to the pipe instead. It also reduces the stress concentration from the base of the hub. Welding neck flanges remove stress concentration and allow full working pressure and they are often used for high pressure applications. The inside diameter of the flange is designed to match the pipe's inside diameter. Weld neck pipe flanges are typically provided with a raised face, flat face, or RTJ facing.
Description:
A Companion Flange, sometimes referred to as a hub, is a flange that corresponds to another flange. It has bolt holes that align with another flange is a trait of this type of flange. Usually a companion flange features a Raised Face (RF) or Ring Joint (RTJ), with a threaded outlet. Also called a Threaded Flange by some people.
API 16A High pressure DSA Double Studded Adapter Flange for Sale
Double Studded Adapter Flange (DSAF) or Double Studded Adapter (DSA) is a flange with a through bore and a ring groove on each side, drilled and tapped bolt hole sets on both sides and tapped end studs complete with nuts fitted on both sides. Unlike a spacer, the two sides are usually different in size and/or pressure rating. Double studded adapter flanges are commonly utilised to connect and adapt flanges with different nominal sizes, pressure ratings, and configurations.
All of our double studded adapter flanges(DSAF) are fully designed, manufactured, and tested according to API 6A and NACE MR0175 standards. The standard material is high quality integral forged AISI4130 alloy. Available in sizes from 1-13/16" to 30" and working pressure up to 15000PSI. For sour service, all ring grooves can be inlaid with stainless steel SS316 or inconel 625 for better protection. The studs and nuts are available with Zinc Coated, Cadmium Coated, or Xylan Coated. Other sizes, material, and pressure ratings are also available upon request. Aside from API6A double studded adapter flanges(DSAF), we also produce and supply other types API 6A flanges, such as threaded flanges, spacer spool flanges, blind flanges, companion flanges, target flanges, test flanges, and adapter spools for all client needs.
Double studded adapter flange is a combination of flanges of different sizes and pressure ratings.
Sanmon supplies ideal DSA for reliable and consistent performance on their production system. Our adapter flanges are in various sizes and pressure ratings as per customer's specified thickness, consistent with design considerations.

Welding Neck (WN) FlangeThe Welding Neck (WN) Flange is a flange designed to be welded to a pipe. The flange has a long tapered hub that is welded to the pipe to form a strong, leak-free connection. The flange also has a flat circular plate with bolt holes to secure the flange to another flange or piece of equipment.
Description
A Welding Neck (WN) Flange is a type of flange used in piping systems to connect pipes and equipment together. It is designed to be welded to the pipe or fitting and then bolted to another flange or piece of equipment. The WN flange has a long tapered neck that is welded to the pipe or fitting, and a flat face that extends out from the neck. The flat face of the flange provides a surface for the gasket to seal against, and the bolts are tightened to compress the gasket and create a leak-tight seal. The neck of the WN flange also provides reinforcement to the connection, which makes it suitable for use in high-pressure and high-temperature applications. The tapered design of the neck reduces stress concentrations and distributes the load evenly across the flange, which helps to prevent leaks and failures.
Threaded flanges are not suitable for pipelines with thin wall thicknesses because it is difficult to cut threads on such pipelines.
Description
Threaded flanges are designed to use threads to connect flanges to piping. Threaded flanges are used to connect pipes together in a safe, leak-free manner. They are often used in industrial pipelines where the flow of fluids or gases needs to be carefully controlled. Threaded flanges are designed to screw onto the end of a pipe, creating a tight seal that prevents leaks and ensures that the pipe operates at maximum efficiency. In addition to being used to connect pipes together, threaded flanges can also be used to connect other piping components such as valves, pumps and fittings. This makes them a versatile component that can be used in a variety of different piping configurations.
Threaded flanges are typically made from materials such as carbon steel, stainless steel or alloy steel. The material used will depend on the specific requirements of the pipeline and its operating environment.
The main advantage of threaded flanges is that they do not require welding to connect to the pipe. The ability to form joints without welding is a considerable advantage and is critical in certain locations and industries such as gas stations, hexane plants, flammable liquid stores, and other explosive areas (Ex zones). If welding is not required, the potential source of ignition has been removed. Another advantage is that threaded flange fittings are faster and easier to assemble and disassemble than welded flange fittings.
Threaded flanges are not suitable for pipes with thin wall thicknesses, as it is more difficult to cut threads on such pipes. In some cases, sealing welds can be used to improve the integrity of the flange and reduce the potential for leakage. Adding a seal weld increases the integrity of the flange, but it also makes the joint more difficult to assemble and disassemble (because the weld makes it a permanent joint).
