Hollow Carbon Seamless Steel Pipe SCH40 ASTM A106 5mm Round Tube
We supply high-performance high pressure high temperature (HPHT) seamless low alloy steel tubes manufactured in strict compliance with ASTM A335 (material standard) and ASME B36.10 (dimension standard), made from premium A335 P9/P11 low alloy steel, with specification 3/4" (DN20), SCH80 heavy wall thickness, designed for extreme industrial working conditions.
ASTM A335 P9 and P11 are high-quality low alloy chromium-molybdenum (Cr-Mo) steels, renowned for their exceptional high-temperature strength, creep resistance, oxidation resistance, and excellent pressure-bearing capacity. These alloys can stably operate under high pressure (up to Class 900+) and high temperature (up to 550℃), effectively resisting corrosion and thermal fatigue in harsh industrial environments. The seamless manufacturing process ensures a smooth inner and outer surface, no welding seams, minimizing fluid resistance and avoiding leakage risks, while the SCH80 heavy wall thickness further enhances the tube’s durability and pressure resistance.
As a professional alloy steel tube supplier, we focus on product performance and reliability, ensuring each tube meets ASTM A335 standards and undergoes strict quality control. The P9/P11 seamless tubes are specifically designed for high-pressure, high-temperature piping systems, widely used in scenarios requiring stable performance under extreme conditions, easy to weld and install, ensuring long-term operational safety and efficiency.

Introduction
Stainless steel seamless steel pipe is a kind of long steel with hollow section and no joints around. Stainless steel seamless pipe
Features of stainless steel seamless pipe:
First, the thicker the wall thickness of the product is, the more economical and practical it is. The thinner the wall thickness is, the higher the processing cost will be; Secondly, the process of the product determines its limited performance. Generally, the precision of seamless steel pipe is low: uneven wall thickness, low brightness on the inner and outer surfaces of the pipe, high sizing cost, and pockmarks and black spots on the inner and outer surfaces are not easy to remove; Third, its detection and shaping must be handled offline. Therefore, it shows its advantages in high pressure, high strength and mechanical structure materials.
A335P91 is a kind of high pressure and high temperature resistant steel. P91 bars, plates, pipes and pipe fittings. P91 is generally a355p91 in terms of title, which is equivalent to the national standard 10Cr9Mo1VNb. It is a material of high-pressure and high-temperature steel pipe. The American standard is ASME sa-335/sa335m, with tensile strength ≥ 585 (MPA), yield strength ≥ 415 (MPA), and elongation ≥ 20 (%). P91 is characterized by thinner pipe wall thickness. Compared with other steel materials, the material consumption is reduced by more than 40%, and the material and installation cost are saved by more than 30%. Due to the reduced self weight of P91 pipe, the load of supports and hangers is also relatively reduced, which is convenient for support and installation.
application
It can be used as steel pipe for high-temperature superheater and reheater of subcritical and supercritical boilers with wall temperature ≤ 625 ℃, as well as high-temperature header and steam pipe with wall temperature ≤ 600 ℃, as well as nuclear electric heat exchanger and furnace pipe of petroleum cracking unit.
