High Tempreture High Pressure Seamless Carbon Steel Pipe A106 GrB 5" SCH40 ANSI B36.19

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.
