Weldoflange

What is Weldoflange

A Weldoflange is a special branch outlet fitting that combines a welded branch outlet and a flange connection into one integrated component.

Compared with a standard weldolet, a weldoflange provides a ready-to-use flanged end for bolted connection. Compared with using a separate weldolet plus flange, it can reduce welding work, installation space, and alignment problems.

Weldoflanges are commonly used for connecting valves, instruments, branch pipelines, and equipment nozzles to main pipelines.

Advantages of Weldoflange

Integrated Branch and Flange Design

Weldoflange combines the reinforced branch outlet and flange connection into one compact component.

Reduced Welding Work

Compared with using a separate outlet fitting and flange, weldoflange can reduce welding operations and installation time.

Convenient Bolted Connection

The flange end allows valves, instruments, equipment, or branch pipelines to be installed and removed easily.

Reliable Sealing Performance

Accurate sealing face machining helps reduce leakage risk in branch pipeline systems.

Strong Reinforced Structure

The forged outlet body provides reliable reinforcement for branch connections under pressure and temperature changes.

Multiple Standard Options

Products can be manufactured according to MSS SP-97, ASME, EN, DIN, JIS, and customer drawings.

FAQ

Q: What is a Weldoflange?
A: A weldoflange is a reinforced branch outlet fitting with an integral flange connection end.

Q: What is the difference between Weldoflange and Weldolet?
A: A weldolet usually has a welding outlet end, while a weldoflange has a flange end for bolted connection.

Q: What is the difference between Weldoflange and Nipoflange?
A: Both are flanged branch outlet fittings. Weldoflange emphasizes welded branch reinforcement, while nipoflange usually refers to a nipple-style outlet body with a flange end.

Q: Can Weldoflange be customized?
A: Yes. OD, ID, thickness, outlet length, bore size, bolt holes, sealing face, material, and coating can be customized.

Q: What standards are available?
A: MSS SP-97, ASME, EN, DIN, JIS, and customer drawings are available.
