Consumption of current international ASTM A**5 P5 alloy pipe half the
share of the total amount of steel only for the developed
countries, ASTM A**5 P*1 alloy pipe using the field expanded to
provide a broader space industry development. According to the
Association of China special steel ASTM A**5 P9 alloy seamless pipe
and tube
Branch of study, future petrochemical project in China, ASTM A**5
P9 alloy seamless pipe average annual growth in demand of up to
***0% of long products.
　　1. seamless steel tube
　　Seamless steel tubes for its manufacturing, is divided into
hot rolling (squeeze) seamless steel pipe and drawing (rolling)
seamless steel pipe in two ways. Drawing (rolling) tubes consists
of a circular pipe and special pipe in two ways.
　　a． Alloy seamless pipe process overview
　　Hot-rolled (squeeze seamless steel tubes): perforation of
tube billet heating → → → → three-roll cross rolling, rolling or
extrusion tube removal → sizing (or reducing) → → → → cooling slab
tube straightening hydraulic pressure test (or testing) → tags →
finished.
　　Drawing (rolling) seamless steel pipe: round tube heating → →
→ → → start → annealing pickling oil perforation (copper) →
multi-pass drawing (cold rolled) → → → → straightening hydraulic
test of heat treatment of blank tube (inspection) → tags →
finished.
　　b． Alloy steel tube, seamless steel tube, because of their
different purposes and divided into several types:
GB********8 (high pressure boiler seamless steel tubes). Mainly
used in power stations and nuclear power plant boiler high
temperature, high pressure fluid set of boxes and pipes.
Representative materials such as *0G, *2Cr1MoVG *5CrMoG.
GB********9 (ships with carbon steel and carbon manganese steel
seamless steel tubes). Mainly used in the ship's boiler and
overheating I, level II pressure pipe, etc. On behalf of the **0,
**0, **0 grade material.
GB/T********8 (structural seamless). Mainly used for general
structural and mechanical structures. Representative materials
(grade): steel, carbon steel, *0; steel Q**5, *0Cr *0Cr, *0CrMo,
****5CrMo, *2CrMo.
　　GB/T********8 (transmission fluid seamless steel tubes).
Mainly used in the transmission fluid pipe on a large engineering
and equipment. Representative materials (grade) to *0, Q**5,
etc.
　　GB********8 (low and medium pressure boiler seamless steel
tubes). Mainly used in industrial boilers and boiler to transport
low pressure fluid in pipe. Represents the material is steel,
*0,.
　　GB********0 (high pressure seamless steel tube for
fertilizer). Mainly used to transport high temperature high
pressure fluid on fertilizer equipment pipe. Represents the *0 g,
*2CrMo material, *2Cr2Mo, etc.
　　GB********6 (seamless steel tubes for petroleum cracking).
Mainly used for oil refinery and transmission fluid pipe of the
boiler, heat exchanger. Its representative material is *0 kg,
1Cr5Mo, 1Cr*9Ni*1Nb, etc.
　　GB*********0 (seamless gas cylinders). Mainly used in the
production of gas, hydraulic cylinders. His representative material
*7Mn, *4Mn2V, *5CrMo, etc.
　　GB/T*********8 (hot rolling seamless steel tube for hydraulic
prop). And mainly for the production of coal mine hydraulic support
cylinder, cylinder, hydraulic cylinder, and other columns. On
behalf of the *0 material, *5 g, etc.
　　GB********6 (diesel engine with high-pressure seamless steel
tubes). Mainly used in the injection system of diesel engine high
pressure oil pipe. Her steel for cold-drawn tubes in General, on
behalf of the material is *0A.
　　GB/T********3 (cold-drawn or cold precision seamless steel
tubes). Mainly used in mechanical dimensions, requirements for
pressure equipment structure, carbon steel pipe of high precision,
good surface finish. His representative material, *0 steel.
　　GB/T********6 (cold-drawn shaped steel tube of seamless).
Mainly used for making various structural components and parts,
made of quality carbon steel and low alloy structural steel.
　　GB/T********8 (precision of hydraulic and pneumatic cylinder
diameter seamless pipe). Mainly for the production of hydraulic and
pneumatic cylinder with precisio
