Alloy Steel Pipes & Tubes

Alloy steel pipes and tubes are purely made of high quality steel that is tested for its standards. They can be used under high temperatures and pressures. They are used in different industries across the world. Alloy steel pipes are used in chemical industries to carry the fluids. They are available in different shapes and sizes according to the client specifications. Alloy steel pipes and tubes are resistant to corrosion.

Size Range: 1/8" - 26"
Schedules: 20, 30, 40, Standard (STD), Extra Heavy (XH), 80, 100, 120, 140, 160, XXH

Alloy Steel contains some quantities of elements like nickel, chromium, silicon, manganese, tungsten, molybdenum, vanadium and small amounts of other commonly accepted elements such as manganese, sulfur, silicon, and phosphorous except carbon. This is purely tested and verified by ASTM for better use in different industries.

They are used mostly in drilling of oil and gas from wells. These are resistant to corrosion and can be used under high temperature and pressure. Tubes are used in day to day life, catering to the domestic, professional or industrial needs

Size Range: 1/2" to 5"
Schedules: in outdise diameter and 0.035 to 0.500in (0.9 to 12.7mm) inclusive in minimum wall thickness.

Size Range: 16"
Schedules: 75 mm wall thickness.

ASTM A691 specification covers carbon and alloy steel pipe, electric-fusion- welded with filler metal added, fabricated from pressure-vessel-quality plate of several analyses and strength levels and suitable for high-pressure service at high temperatures.

Heat treatment may or may not be required to attain the desired mechanical properties.

Size Range: 1/8"
Schedules: 0.4 TO 12.7 mm wall thickness.

Grade contating the letter, H, in their desigination, have requirements different from those of similar grades not containing the letter, H. These different requirements provide higher creep-rupture strength than normally achievable in similar grades without thses different requirements.

Ferritic alloy cold- finished steel tubes shall be free of scale and suitable for inspection. A slight amount of oxidation is not considered scale.

Size Range: 1/2" to 42" Seamless, 14" to 100" Welded
Schedules: 2mm to 100mm wall thickness

ASTM A333 (ASME S/A-333) Pipe grades permit low temperature service. This specification covers nominal (average) walled pipe almost exclusively in seamless.  Several grades of ferritic steel are included. Some product sizes may not be available under this specification because heavier wall thicknesses have an adverse effect on low-temperature impact properties.

ASTM A333 Grade 6 is the part of standard covers wall seamless and welded carbon and alloy steel pipe intended for use at low temperatures. ASTM A333 Grade 6 alloy pipe shall be made by the seamless or welding process with the addition of no filler metal in the welding operation.

Size Range:
Schedules: 75 mm wall thickness.

This specification covers several grades of minimum wall thickness, seamless and welded, carbon and alloy- steel tubes intended for use at low temperatures.

Some product sizes may not be available under this specification because heavier wall thickness have an adverse affect on low temperature impact properties.
