ASTM A334 Grade 6 Pipes and Tubes are designed for low-temperature service applications where reliable performance is required. The ASTM A334 specification covers seamless and welded carbon steel pipes intended for use in pressure piping and heat transfer systems operating at low temperatures. ASTM A334 pipes are available in several grades including Grade 1, Grade 3, Grade 4, Grade 6, Grade 7, Grade 8, Grade 9, Grade 10 and Grade 11. These pipes are manufactured under controlled heat treatment processes to achieve the required mechanical properties and microstructure. To ensure quality and compliance, the pipes undergo various inspections and tests such as tensile testing, hydrostatic testing, impact testing and dimensional inspection.

Specification:
ASTM A334 Grade 6 pipes and tubes are supplied in a wide range of sizes and wall thicknesses to meet different industrial requirements. These pipes are generally available in schedules such as SCH 20, SCH 30, SCH 40, SCH 80, SCH 100, SCH 120, SCH 140 and SCH 160 including standard, extra heavy (XH) and double extra heavy (XXH) thicknesses. End connections can be supplied as plain end, beveled end or threaded end depending on the application. Manufacturing processes include cold drawn, ERW, fabricated and welded pipes. The pipes and tubes are available in different forms such as round pipes, square tubes, rectangular tubes, hydraulic tubes and U-tubes. Lengths can be supplied as single random, double random or as per customer requirement, and protective plastic caps are fitted at pipe ends to prevent damage during transportation.

All ASTM A334 Grade 6 pipes and tubes undergo strict quality inspection including chemical composition analysis, dimensional verification, elongation testing, flaring test and hydrostatic testing as required by ASTM standards. Mill test certificates are issued in accordance with EN 10204 to ensure full traceability and compliance with international specifications. These pipes are widely supplied for industrial applications requiring reliable performance in low-temperature environments.
