OTHER PIPE SPECIFICATIONS
Covers high-test line pipe with greater tensile and bursting strengths than pipe made to API 5L. Seamless or welded, sizes 6-5/8 inch OD – 36 inch, Grades X-42, X-46, and
X-52. Numerical designation in grade indicates minimum yield, thus X-42=42,000 lbs. min. yield steel, etc. OD, weight and wall tolerances, tensile and flattening tests and marking requirements are same as outlined in API 5L.
Covers electric-fusion (arc)-welded straight seam or spiral seam steel plate pipe 16 inch and over (ID or OD as specified by customer), with walls up to 3/4 inch inclusive. Pipe intended for conveying liquid, gas, or vapor.
Covers two grades (A and B) of electric-resistance-welded pipe, 30 inch and under, intended for conveying liquid, gas, or vapor. Only grade A is adapted for flanging and bending. Purpose for which pipe is intended should be stated in the order.
Covers two grades (A and B) of electric-fusion (arc)-welded straight-seam or spiral-seam pipe, 4 inch and over, wall thicknesses up to 5/8 inch inclusive. Pipe intended for conveying liquid, gas, or vapor.
Covers electric-fusion-welded pipe for high-temperature, high-pressure service. Generally in sizes 16 inch OD and larger. Pipe is suitable for bending, flanging (vanstoning), and similar forming operations. Several grades of carbon steel and alloy steel plates are covered.
Covers three grades (physical properties) of welded and seamless black pipe piles of cylindrical shape either as permanent load-carrying members or shells to form cast-in-place concrete piles. Not intended to apply to pipe for general structural purposes. Sizes 8-5/8 inch OD through 24 inch OD.
Covers ten grades (designated as TP 304, TP 304L, TP 316, TP 347, etc.) of seamless and welded stainless steel pipe intended for high-temperature and general corrosive service.
Covers seamless and welded carbon and alloy steel pipe for low-temperature service. (Special product note — Yoloy pipe can be certified to meet the requirements of A333, Grade O, for service down to minus 50 degrees F.)
Covers fourteen grades, designated as P-11 (1-1/4 percent chrome, 1/2 percent moly) P-12 (1 percent chrome, 1/2 percent moly) P-5 (4-6 percent chrome, 1/2 percent moly) etc., of intermediate alloy seamless steel pipe intended for high-temperature service and suitable for bending, flanging (vanstoning), and similar forming operations.
