We offer a complete range of butt weld elbow, tee, reducer, bend, cap, cross and stub end, which are available in various size, specification, thickness and shapes for meeting customer’s requirements.

Duplex Steel are known by it’s highly corrosion resistance properties with respect to the standard austenitic grades or high alloyed ferrite.

What is the Duplex Steel Grades?

ASTM A815 UNS S31803 Buttweld Fittings

People described 31803 as a duplex stainless steel with a microstructure of 50:50 austenite and ferrite. The steel combines good mechanical strength (typically up to over 480 MPa yield strength) and ductility with moderate to good corrosion resistance in a variety of environments.

ASTM A815 UNS S32205 Buttweld Fittings

2205 is a duplex stainless steel, with a chemical composition of nearly equal proportions of austenite and ferrite.  This combination allows the alloy to be stronger and tougher than standard austenitic steels.

Schedule 40S Pipe Fittings Weight Chart

The common equal size butt weld fittings are 90 degree elbow, 45 degree elbow and equal tee. Due to the size range, the weight and volume is very important for calculating the transportation cost.

Equal Pipe Fittings Weight Chart

The unequal pipe fittings also called reducing fittings, these are concentric reducer, eccentric reducer & reducing tee, now we provide the weight chart as following. For more dimensions & weight, please contact us.

Stainless Steel Buttweld Fittings Dimensions

ASME B16. 9 Standard

It is the most common used specification standard for Factory-Made Wrought Buttwelding Fittings. It covers the requirements for dimensions, tolerances, ratings, testings and markings.

Buttwelding Fittings Catalogue

• To Change Directions

Butt Weld Elbows are used to connect two pipes with same or different nominal diameters, and to make the pipe turn to a certain direction of 45 degree or 90 degree.

Types: 90 Degree Elbow, 45 Degree Elbow, 180 Degree Elbow. Stainless Steel Pipe Bend

• To Provide Branches

Butt Weld Tees are used to join three different pipes forming a junction. It is normally called as “3-way fitting”. It symbolizes an alphabet “T” which include two inlets and single outlet.
There are two types that Equal Tee and Reducing Tee.

• To Block Pipeline

Butt Weld Caps are used to weld and block end of pipeline. We call it as Pipe Cap and End Cap.

• To Reduce Pipe Dimensions

Butt Weld Reducers are connected with pipes in different diameters.
Concentric Reducer, Eccentric Reducer, Reducing Elbow

• To Use With Flanges

Lap Joint Stub Ends are used in combination with a lap joint flange to make flanged connections.

Package of Stainless Steel Buttweld Fittings

We marked all Stainless Steel Buttweld Fittings with Grade, Lot No, Size, Standard and Schedule Thickness. The workers wrapped Stainless Steel Pipe Fittings with film individually. For the small diameter pipe fittings, we will pack them into wooden cases in the end, and use pallets to pack large diameter pipe fittings.

Buttweld Fittings vs Socket Weld Fittings

• Standard

ASME B16.9 for buttweld fittings
ASME B16.11 for socket weld fittings

• Dimensions

BW : 1/2″ to 48″

SW: 1/8″ to 4″

• Manufacturing

BW: Hot Forming

SW: Forging

• Price

Normally, the price of socket weld fittings is higher than butt weld fittings in similar size. But the extra cost of butt weld is higher for installation, considering labor cost and skilled welder.
