27SiMN Quenched Thiab Tempered Steel Yeeb Nkab API Series Pipeline Steel Yeeb Nkab Carbon Steel Round Pipe

Product Description

Cov pa roj carbon steel yeeb nkab lossis carbon steel yeeb nkab yog ua los ntawm steel ingot los yog cov yeeb nkab khoom dawb paug los ntawm perforation, thiab ces ua los ntawm kub dov, txias dov los yog txias txias. Carbon steel yeeb nkab plays lub luag haujlwm tseem ceeb hauv Tuam Tshoj txoj kev lag luam steel yeeb nkab. Cov khoom siv raw ntawm carbon steel yeeb nkab yog round raj dawb paug. Lub raj puag ncig yog txiav thiab ua tiav los ntawm lub tshuab txiav, thiab qhov khoob nrog kev loj hlob ntawm li 1m raug xa mus rau qhov cub rau cua sov los ntawm txoj siv conveyor. Lub billet raug xa mus rau lub qhov cub kom cua sov ntawm qhov kub ntawm txog 1200 degrees Celsius. Cov roj yog hydrogen lossis acetylene. Kev tswj qhov kub thiab txias hauv qhov cub yog qhov teeb meem tseem ceeb. Tom qab lub round tube billet tawm ntawm lub cub tawg, nws yuav tsum tau pierced los ntawm lub siab piercer. Feem ntau, qhov ntau tshaj piercer yog lub conical yob piercer. Cov piercer no muaj kev ua haujlwm siab, cov khoom lag luam zoo, loj perforation nthuav dav thiab tuaj yeem hnav ntau qib steel. Tom qab perforation, lub puag ncig lub raj dawb paug yog txuas ntxiv dov los ntawm peb yob hla dov, nruam dov lossis extrusion. Tom qab extrusion, tshem tawm cov yeeb nkab rau sizing. Lub tshuab sizing rotates rau hauv steel embryo ntawm kev kub ceev los ntawm conical laum los ua ib tug steel yeeb nkab. Sab hauv txoj kab uas hla ntawm cov yeeb nkab steel yog txiav txim siab los ntawm qhov ntev ntawm lub tshuab sizing me ntsis. Tom qab sizing, cov yeeb nkab steel nkag mus rau hauv cov cua txias ntauwd thiab txias los ntawm cov tshuaj tsuag dej. Tom qab txias, cov yeeb nkab steel yuav ncaj. Tom qab straightening, cov yeeb nkab steel raug xa mus rau cov hlau tsis haum (los yog hydrostatic test) los ntawm txoj siv conveyor rau kev kuaj pom qhov tsis zoo. Yog tias muaj cov kab nrib pleb, npuas thiab lwm yam teeb meem hauv cov yeeb nkab steel, lawv yuav raug kuaj pom. Cov kav hlau yuav tsum nruj me ntsis xaiv los ntawm tes tom qab kev tshuaj xyuas zoo. Tom qab cov yeeb nkab steel raug tshuaj xyuas, tus naj npawb, specification, ntau lawm batch tooj, thiab lwm yam yuav tsum tau txau nrog cov xim. Thiab hoisted mus rau hauv lub warehouse los ntawm crane.

27SiMn Steel Pipe = 27 silicon manganese steel yeeb nkab, uas yog ib qho ntawm cov ntaub ntawv ntawm seamless steel yeeb nkab, thiab cov ntsiab lus carbon yog nyob nruab nrab ntawm 0.24-0.32%. SIMN yog teev tseg vim hais tias cov ntsiab lus ntawm silicon manganese nyob rau hauv tsib lub ntsiab (carbon C, silicon Si, manganese Mn, phosphorus P, sulfur s) yog hais txog 1.10-1.40%.

Cov ntsiab lus: nws tau ua haujlwm hauv kev lag luam seamless steel yeeb nkab hauv Suav teb rau ntau tshaj 20 xyoo. Cov pab pawg muaj ntau tshaj 10 seamless steel yeeb nkab ntau lawm kab, feem ntau ua 27SiMn quenched thiab tempered steel yeeb nkab, API series pipeline steel yeeb nkab, carbon steel round yeeb nkab thiab American standard series steel yeeb nkab. Nws muaj ntau yam kev siv. Tam sim no nws cov neeg siv khoom tseem ceeb tau tsom mus rau South Africa, Central Asia, Europe thiab lwm lub tebchaws, nrog ntau txhiab tons ntawm cov khoom lag luam los muab cov neeg siv khoom xav tau.
