     In addition to the chemical composition and mechanical properties of 1Cr18Ni9 and 1Cr18Ni11Nb high pressure boilers, the hydraulic pressure test should be done by root, and the test will be expanded.

321 stainless steel pipe s are delivered in heat treatment. In addition, there are certain requirements for the microstructure, grain size and decarburizing layer of finished steel tube.

A seamless steel tube for geological drilling and oil drilling. In order to ascertain the structure of underground strata, groundwater, oil, natural gas and mineral resources, the drill is used to drill Wells.

Mining more from drilling, oil and gas geological drilling in oil drilling in seamless steel pipe is the main drilling equipment, mainly including core tube, core tube, casing, drill pipe, etc.

Because the drill pipe has to be drilled deep into the depth of several thousand meters, the 1cr5mo alloy pipe.

6:  working condition is very complex, drill pipe under pull, pressure, bending, torsion and uneven impact load stress, but also by mud,

rocks and wear, therefore, requires tubing must have sufficient strength, hardness, wear resistance and impact toughness, steel pipe steel with

“DZ” pinyin “(geology) plus number one on behalf of the said steel yield point, common steel grade DZ45 MNB 45, 50 mn; DZ50 40 mn2, 40 mn2si; DZ55 40 mn2mo, 40 MNVB;

40 mnmob DZ60, DZ65 27 mnmovb. All steel pipes are delivered in heat treatment.

Oil cracking pipe: pipe, heat exchanger tube and tube for oil refinery. The products are made by high quality carbon steel (10, 20),

alloy steel (12CrMo, 15CrMo), heat resistant steel (12Cr2Mo, 15Cr5Mo), stainless steel (1Cr18Ni9, 1Cr18Ni9Ti).

7:  321 stainless steel pipe: with all kinds of stainless steel hot rolling and cold rolling stainless steel tube,

pipe is widely used in petroleum, chemical industry equipment and various USES of the stainless steel structural parts,

in addition to ensure that the chemical composition and mechanical properties,

all steel pipe is used as the fluid under pressure to keep the water pressure test. All special steel pipes shall be guaranteed according to the regulations.

Welding tube: also called welding tube, is made by bending and forming with steel or steel strip. The weld pipe is divided into straight seam welded pipe and spiral welded pipe.

According to the application is divided into general welded pipe, galvanized welded pipe, oxygen blowing metric welded pipe, welded pipe, wire casing, roller tube, deep well pump tube, 321 stainless steel tube, automobile use pipe, transformer, electric welding thin wall pipe, welded pipe and spiral welded pipe.

8;  The stainless steel tube is a long strip of steel with hollow section and no seam.

    The pipe has a hollow section and is used as a conduit for conveying fluids such as oil, gas, gas, water and certain solid materials.

    The seamless pipe is divided into hot rolled tube, cold rolled tube, cold tube, extruded tube and top tube 16Mn seamless tube

THE DIFFERENCE AND CONNECTION BETWEEN 304 AND 321 STAINLESS STEEL PIPE.

The 304 stainless steel pipe is a brand of stainless steel manufactured according to the ASTM standard. The stainless steel tube is equivalent to the 0Cr19Ni9 (0Cr18Ni9) stainless steel pipe in our country. 304 contains 19% of chromium and 9% nickel.

The 321 stainless steel pipe tube is the most widely used for stainless steel, the equipment for food, general chemical equipment, and the atomic energy industry.

The 321 stainless steel pipe tube is a versatile stainless steel tube that is widely used to make equipment and parts that require good overall performance (corrosion resistance and molding).

The 321 stainless steel pipe tube is the most widely used stainless steel, heat resistant steel. Used in food production equipment, chemical equipment, nuclear power, etc.

321 stainless steel pipe tube chemical composition specification C Si Mn P S Cr Ni (nickel) Mo

SUS304 less than or less than 0.08 is less than or equal to 1.00 or less than 0.03, or less than 0.05, or 0.03, 18.00-20.00, 8.25 ~ 10.50 –

In air or chemical corrosion resistant to corrosion medium of a kind of high alloy steel, stainless steel is a beautiful surface and corrosion resistant performance is good, need not after surface treatment, such as color of plating and the surface of the stainless steel inherent performance, used in a variety of steel a, often called stainless steel. It represents the performance of 13 chrome steel, 18-8 chrome nickel steel.

From the perspective of metallography analysis, because the stainless steel containing chromium and make the surface form very thin chromium film, the film is isolated from intrusion in the steel corrosion of oxygen. To maintain the corrosion resistance inherent in stainless steel, steel must contain more than 12 percent chromium.

321 stainless steel pipe seamless steel pipe (ASTM A312/213 TP321 ) is used in the manufacture of various structural low intermediate pressure boiler superheated steam pipe, water pipe and locomotive boiler superheated steam pipe, pipes, small pipe and arch brick works of high quality carbon structural steel hot rolling and cold drawing (rolling) seamless steel tube.

321 stainless steel pipe: mainly used in the manufacture of high pressure and over pressure steam boiler pipes, etc. With high quality carbon structural steel, alloy steel and stainless heat resistant steel seamless steel tube, the boiler tube by the party under high temperature and high pressure pipe and works in high temperature flue gas and steam will happen under the action of oxidation and corrosion, so the steel pipe with high rupture strength, high oxidation resistance, and have good organizational stability, hydraulic prop.

The stainless steel pipe has a steel number:

There are 20G, 20MnG and 25MnG steel. 304 stainless steel pipe.

The alloy structural steel number 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc. Rust resistant steel is used in 1Cr18Ni9 and 1Cr18Ni11Nb high pressure boiler tube except for the chemical composition and mechanical properties, the water pressure test should be done by the root, which should be expanded and flat test.

The stainless steel tube shall be delivered in heat treatment. In addition, there are certain requirements for the microstructure, grain size and decarburizing layer of finished steel tube. A seamless steel tube for geological drilling and oil drilling. In order to ascertain the structure of underground strata, groundwater, oil, natural gas and mineral resources, the drill is used to drill Wells
