What are ASTM A234 WP91 Alloy Buttweld Fittings?
ASTM A234 WP91 Pipe Fittings are a category of alloy steel buttweld pipe fittings manufactured from Chrome Moly Alloy Steel WP91. They are mainly used in high-pressure and high-temperature piping systems due to their excellent mechanical strength and resistance to creep, oxidation, and corrosion.
- ASTM A234 – This is the specification standard for alloy steel and carbon steel pipe fittings, covering seamless and welded types.
- WP91 – This grade indicates the alloy composition, containing chromium (Cr) and molybdenum (Mo), which provide improved strength and resistance at elevated temperatures.
These fittings are designed to connect pipes, change direction, reduce pipe sizes, or stop the flow in piping systems. ASTM A234 WPB Carbon Steel Pipe Fittings are especially popular in industries where strength, toughness, and pressure resistance are essential.
Key Features of ASTM A234 WPB Steel Pipe Fittings
- Excellent mechanical strength.
- High resistance to stress and pressure.
- Cost-effective compared to stainless steel alternatives.
- Easy to weld and fabricate.
- Suitable for both seamless and welded applications.
Types of ASTM A234 WPB Carbon Steel Buttweld Fittings
At Solitaire Fittings, we offer a complete range of fittings, including:
➤ ASME SA 234 Gr WPB Pipe Elbow
Used to change the direction of the pipe, elbows are available in 45°, 90°, and 180° angles. We supply Carbon Steel WPB Elbow Dealer in India products in both long radius (LR) and short radius (SR) types.
➤ ANSI B16.28 ASTM A234 WPB Reducer
Reducers are used to connect pipes of different diameters. We provide both Concentric Reducers and Eccentric Reducers, including Carbon Steel A234 WPB Smls Reducer for high-pressure applications.
➤ SA234 Grade WPB Tee
Tees are used to branch the pipeline. Available in Equal Tee and Reducing Tee, these fittings ensure smooth flow distribution in the system.
➤ ASTM A234 Gr WPB Cap
Pipe caps are designed to block the pipe end and prevent leakage. They are commonly used for pipe closures during testing or permanent sealing.
➤ Carbon Steel Grade WPL6 Pipe Elbow
WPL6 is another low-temperature carbon steel grade under the A234 standard. These fittings are ideal for cryogenic and low-temperature applications.
➤ Carbon Steel WPB Butt weld Pipe Fittings
These include bends, crosses, stub ends, and collars, which are essential for constructing and maintaining pipelines across industries.
Material Composition of Chromium Molybdenum A234 WP91 Pipe Fittings
The composition of ASTM A234 WP91 Cr-Mo Pipe Fittings includes chromium and molybdenum as the main strengthening elements.
- Chromium (Cr) – Improves corrosion and oxidation resistance.
- Molybdenum (Mo) – Enhances tensile strength and creep resistance at high temperatures.
- Carbon (C) – Provides hardness and wear resistance.
This combination makes WP91 fittings ideal for critical applications like boilers, heat exchangers, and turbines.
