Alloy 31 Pipe | UNS N08031

Alloy 31 pipes, also known as UNS N08031, 1.4562 are a type of corrosion-resistant piping system. It is made from super-austenitic stainless steel known as Alloy 31. The pipes are designed to withstand harsh environments that are highly corrosive, such as those containing acids, chlorides, and other aggressive chemicals.

Our alloy 31 in pipe form is composed of the following elements:

C – .015% max

Si – .3% max

Mn – 2.0% max

P – 0.04% max

S – 0.03% max

Cr – 26% – 28%

Cu – 1.2% – 1.8%

Fe – Balance

Mo – 6% – 7%

N – 0.15% – 0.25

Ni – 30% – 32%

Your Expert Alloy 31 Pipe Supplier in China

Tuolian specializes in manufacturing alloy 31 pipes for more than 10 years. With its properties, the material become greatly used in various industries, including chemical processing, petrochemical, pharmaceutical, and offshore oil and gas production. They are commonly used in areas where other materials like nickel alloys or stainless steel, have failed due to corrosion.

Some of the specific scenarios where alloy 31 pipes are commonly used include heat exchangers, waste acid recovery equipment, pipe fittings, fine chemicals, organic acid and ester synthesis, sulfuric acid pickling equipment, ore processing, marine scrubber, mineral oil production, and refineries, components for FGD plants, etc.

Tuolian offer different types of alloy 31 pipes, including seamless pipes, welded pipe, ERW pipe, alloy 31 seamless and welded coiled tubing, and corrugated pipes.

At Tuolian, we can manufacture alloy 31 pipe forms using various methods, including seamless and welded. The specific production process will depend on factors such as wall thickness, pipe diameter, and intended use.
