These are electric resistance welded carbon steel tubes conforming to ASTM A178 Grade A, manufactured for use in boilers, superheaters, and heat exchangers. The Grade A composition includes carbon at 0.06 to 0.18 percent, manganese at 0.27 to 0.63 percent, with phosphorus and sulfur each capped below 0.035 percent. Mechanical properties meet a minimum tensile strength of 47 ksi, yield strength of 26 ksi, and elongation of 35 percent, verifying suitability for high-pressure steam applications.
The tubes are produced via ERW and can be supplied with surface treatments such as temporary ASTM A450 coating, galvanizing, immersion oil, lacquer, passivation, or phosphating. Each tube undergoes rigorous testing per ASTM A450, including chemical analysis, tensile and yield strength checks, elongation measurement, flattening, flaring, bending, hardness, blow tests, and nondestructive electric and hydrostatic tests. Packaging options include hexagonal bundles with steel strips, waterproof paper, PVC sleeves, and sackcloth, or heavy tri-wall and wooden boxes to protect against transit damage.
Primarily used in boiler systems for wal panels, economizers, reheaters, and steam pipelines, these tubes are also fit for hydraulic and petrochemical applications. Orders are fulfilled from Shanghai Port with a typical lead time of 45 days from raw material availability, subject to the minimum order quantity of 15 tonnes per dimension. Payment terms are T/T or L/C at sight, with container options of 20GP, 40GP, or bulk shipping.
