Product Description

ASTM A269 Alloy 310s Stainless Steel Coil Tubing

Stainless steels are known as high-alloy steels. They are classified into ferritic, austenitic, and martensitic steels based on their crystalline structure.

Grade 310S stainless steel is superior to 304 or 309 stainless steel in most environments because it has high nickel and chromium content. It offers high corrosion resistance and strength in temperatures up to 1149°C (2100°F).

Frequently Asked Questions (FAQ)

What are the advantages of Grade 310S stainless steel coiled tubing?

Grade 310S contains high nickel and chromium contents, making it superior to 304 or 309 grades. It provides outstanding corrosion resistance and maintains high strength in high-temperature environments up to 1149°C (2100°F).

Why is seamless coiled tubing preferred over welded coiled tubing?

Seamless coiled tubing eliminates the risk of impurities that can occur in welded seams. This improves reliability, enhances corrosion resistance, reduces the number of fittings needed (which minimizes leak risks), and simplifies installation.

What standard and size ranges are available for the coiled pipes?

The coiled pipes comply with ASTM A269 and ASTM A249 standards. Available outer diameters range from 6.52mm to 20mm with wall thicknesses between 0.2mm and 2.0mm. Lengths can reach up to 3500M per coil.

In which industries are stainless steel coiled tubes applied?

They are widely applied in the food and beverage industry, petrochemical processing, CNG piping, boilers, geothermal systems, heat exchangers, instrumentation installations, and oil & gas equipment.

What quality control testing processes are conducted on the tubing?

To guarantee performance, the tubing undergoes compressed testing, flaring tests, bending tests, 100% hardness tests, stretch tests, and air tightness testing.

What alloys and grades are customizable for coiled tubing?

Commonly supplied grades include 304, 304L, 316, 316L, 310S, 321, 347, 904L, duplex 2205, and nickel alloys like Inconel 625, Incoloy 825, and Monel 400.
