Types of Fabricated Steel Pipe Fittings

MRB Forge manufactures a wide range of fabricated steel pipe fittings suitable for diverse piping and process applications.

Fabricated Elbows

Used to change flow direction in large diameter piping, available in 45 and 90 degree configurations built from welded plate sections.

Fabricated Elbows
Fabricated Tees

Provide branch connections in large diameter piping where standard fittings cannot meet size or configuration requirements of the project.

Fabricated Tees
Fabricated Reducers

Connect pipes of different diameters in concentric and eccentric configurations for large bore process piping where standard reducers are unavailable.

Fabricated Reducers
Fabricated Laterals

Provide angled branch connections allowing flow to be directed at a specified angle in pipeline systems and process manifolds.

Fabricated Laterals
Fabricated Crosses

Provide four way branch connections for simultaneous flow distribution in process manifolds, distribution headers and complex piping configurations.

Fabricated Crosses
Fabricated Caps & Closures

Seal ends of large diameter pipes and fittings, providing pressure tight closures for pipeline terminals and temporary isolation applications.

Fabricated Caps & Closures
Fabricated Stub Ends

Used with lap joint flanges for flexible alignment and easy dismantling in large diameter piping requiring frequent maintenance access.

Fabricated Stub Ends

MRB Forge manufactures fabricated steel pipe fittings in a wide variety of materials to meet the performance requirements of different industries and operating environments.

Carbon Steel Fabricated Fittings

Excellent strength and cost effectiveness for high pressure piping. Common grades include ASTM A234 WPB, A420 WPL6 and A860 WPHY.

Stainless Steel Fabricated Fittings

Excellent corrosion resistance for demanding service environments. Common grades include SS 304, 304L, 316, 316L, 321 and 347.

Alloy Steel Fabricated Fittings

Engineered for high temperature and high pressure conditions requiring enhanced mechanical properties and creep resistance.

Duplex Steel Fabricated Fittings

High strength with excellent resistance to pitting and stress corrosion cracking in chloride containing environments.

Super Duplex Steel Fabricated Fittings

Superior corrosion resistance in aggressive offshore and subsea environments where standard duplex grades are insufficient.

Nickel Alloy Fabricated Fittings

Designed for highly corrosive applications involving acids, chemicals and elevated temperatures in demanding industrial services.
