High-pressure alloy pipe is a kind of can show the pressure tube, and use the pipe to transport liquid, it's a lot of more phyletic, steel, brass, stainless steel pipe, and other, and so on.
High-pressure alloy 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, using steel grade are: high quality carbon structural steel grade 20 g, 20 MNG, 25 MNG;15 mog, alloy structural steel steel grade 20 crmog mog, 12, 15 crmog, 12 cr2mog, 12 crmovg, 12 cr3movsitib, etc;Heat resistant steel rust cr18ni9, 1 cr18ni11nb commonly used high pressure tube, in addition to ensure that the chemical composition and mechanical properties by root do water pressure test, flaring, flattening test.Steel tube to heat treatment state delivery.In addition, the microstructure and grain size of finished steel pipe, the decarburization layer also has certain requirements.Geological drilling and oil drilling with seamless steel tube;Proven underground strata structure and groundwater, oil, gas and mineral resources, make use of the rig drilling 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.Due to the drilling pipe to go deep into the thousands of meters formation depth work, working conditions 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 steel yield point, said common steel grade DZ45 MNB 45, 50 mn;DZ50 40 mn2, 40 mn2si;DZ55 40 mn2mo, 40 MNVB;40 mnmob DZ60, DZ65 27 mnmovb.Steel pipe is a heat treatment state delivery.Petroleum cracking tube: used in oil refinery furnace tube, seamless tube heat exchanger tube and pipe.Commonly used high quality carbon steel (10, 20), alloy steel (12 crmo, 15 crmo), heat resistant steel (12 cr2mo, 15 cr5mo), stainless steel cr18ni9 (1, 1 cr18ni9ti) manufacturing.Steel pipe except to the chemical composition and various mechanical properties, and ensure that the water pressure, flattening, flaring test, and the surface quality and nondestructive inspection.Steel pipe in heat treatment state delivery.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 kinds of special steel pipe to guarantee conditions by the regulation.
The main production process: high-pressure alloy pipe tube slab and billet heating, the extension of perforated tube billet, steel pipe.
High-pressure alloy pipe rolling, pipe sizing and reducing, steel pipe cooling and sizing, or can be said to be hot rolled steel heating of embryo perforation pickling of cold drawn carbon burn cut head spray standard packaging products manufacturing method of a kind of seamless steel tube, whose character is: set up each other will have multiple roll rolling stand, to the rolling direction of continuous configuration is more than one type of rods seamless tube mill, in the manufacture of seamless steel tube production line, after rolling on the multi-point measurement after rolling of steel tube wall thickness of the circle direction, according to the determination results, at least, respectively control core rod type of seamless tube mill roll on the final rolling stand all the ends of the shaft position, so that to minimize the uneven wall thickness.
