different length seamless steel pipe
Unlike almost any other material in the world, seamless pipe is not manufactured to a specific length. Rather, a mill will make either single random lengths (SRLs) or double random lengths (DRLs). An SRL ranges from about 18ft to 24ft and a DRL ranges from 35ft to 44ft. This range of lengths is a by-product of the manufacturing process.
Seamless steel pipe has better pressure capacity, strength is higher than ERW welded steel pipe. So it is widely applied in high pressure equipment, and thermal, boiler industries. Generally the welding seam of the welded steel pipe is the weak point, the quality affect overall performance. ASTM Standard for seamless steel pipe. Steel Pipe Dimensions & Sizes Chart (Schedule 40, 80 Pipe Dec 12, 2018 · Different pipe schedule means different wall thickness for the steel pipe in the same diameter. The most frequently indications of schedule are SCH 5, 5S, 10, 10S, 20, 20S, 30, 40, 40S, 60, 80, 80S, 100, 120, 140, 160. The larger the table number, the thicker the surface pipe wall, the higher the pressure resistance.
