Steel Grades in ASTM A589

At UNIACERO, we offer ASTM A589 pipes in two distinct steel grades: Grade A and Grade B. Each grade is meticulously crafted to provide distinct advantages based on your specific requirements. Whether it’s the tensile strength or yield strength you’re considering, our steel grades are designed to meet varied demands, giving you a product tailored for performance and reliability.

Production Tolerance of ASTM A589

Weight—The weight of all types of pipe included in this specification shall vary not more than 6 5 % from that prescribed. The weight tolerance for pipe NPS 4 [DN 100] and under may be determined from the weight of the customary lifts of pipe as produced for shipment, divided by the number of feet of pipe in the lift. For pipe over NPS 4 [DN 100], where individual lengths may be weighed, the weight is applicable to the individual length.

Thickness—The minimum wall thickness shall be not more than 12.5 % under the nominal wall thickness specified.

Outside Diameter—For pipe NPS 11⁄2 [DN 40] and under, the outside diameters shall vary not more than 1⁄64 in. [0.4 mm] from the outside diameter specified. For pipe NPS 2 [DN 50] and over, the outside diameter shall vary not more than 6 1 % from the size specified. 10.2.3 Inside Diameter—For Type II pipe, the inside diameter at any point, shall permit passage of a drift pin having a length and diameter as indicated in Table 6, Table 7, and Table 18.

Lengths-Unless otherwise specified on the purchase order, pipe lengths shall be in accordance with the following regular practice:

Types I, II, and IV pipe may be furnished in single random lengths of 16 to 22 ft [4.9 to 6.7 m].

Type III pipe may be furnished in a random range from 3 to 6 ft [0.9 to 1.8 m] or 6 to 10 ft [1.8 to 3.0 m] as specified.

Random lengths other than indicated in 10.3.1 and cut lengths, shall be subject to negotiation and shall be indicated on the purchase order.
