ASTM A234 Pipe Fittings

Alloy Steel WP22 Fittings are more popular because their high properties and wide application fields. Recently,they are totally in a large demand.

ASTM A234 covers wrought carbon and alloy of seamless and welded construction for moderate and high temperature service. They are for use in pressure piping and in pressure vessel fabrication as well.

Alloy Steel WP22 Fittings Export

We export A234 WP22 Pipe fittings to many countries. For example, we exported OD530 Alloy Steel WP22 Seamless Bend to Vietnam, A234 WP22 Butt Weld Cap to Singapore, 8 inch Butt Weld Equal Tee to Lagos Project, Concentric Reducer to Angola, and DN350 90 Degree Elbow to Australia. They were used in many projects like smelting plant, gas pipeline, power generation, heat exchangers and specialty chemicals. You may find that most of Alloy WP22 Pipe Fittings are butt weld fittings.

Alloy Steel Buttweld Fittings

Butt Weld Fittings are specified in ASME/ANSI B16.9. They usually have a large dimension ranges Usually we take seamless tube and welded tube as original material. Seamless fittings have a better leak proof. And weld fittings is easier to process.

What is the types of alloy steel pipe fittings? We can divide them as their function

• Connect different diameter pipes: Concentric and Eccentric Reducer, Swage Nipple
• Block off flow of fluid: Pipe Cap and End Cap.
• Provide outlet for run pipe: Equal Tee and Reducing Tee
• Change direction of flow: 45 Degree Long Radius Elbow, 90 Degree Short Radius Elbow, Pipe Bend

Chrome Moly Pipe Fittings

Since ASTM A234 WP22 is a Chrome Moly alloy steel, we can know that Alloy Steel Fittings have the common features as below.

• Resistant to high temperature and hydrogen corrosion.

Chrome and Moly play an significant role in improving the temperature and corrosion resistance.

• Good Process-ability and Weld-ability

The low carbon content makes it soft and easy to be formed into different shapes.

• Other Features

Alloy Steel WP22 Fittings have a good oxidation resistance and creep strength to 1500 Degree F (816 Degree C).
