Factory Directly Supply High Pressure Seamless Boiler Tube / Yeeb Nkab
Peb tuaj yeem ua tau yooj yim feem ntau ua tiav peb cov neeg siv khoom hwm nrog peb cov khoom zoo tshaj plaws, tus nqi zoo heev thiab kev txhawb nqa zoo heev vim peb tau muaj cov kws tshaj lij thiab ua haujlwm ntau dua thiab ua haujlwm zoo rau cov khoom siv yeeb nkab. Peb sov siab txais tos cov phooj ywg los ntawm txhua qhov chaw ntawm lub neej los koom tes nrog peb.
Tianjin Sanon Steel Pipe Co., Ltd yog ib txwm hais txog kev ua tau zoo raws li lub tuam txhab lub hauv paus, nrhiav kev txhim kho los ntawm qib siab ntawm kev ntseeg siab, ua raws li ISO kev tswj hwm tus qauv nruj me ntsis, tsim lub tuam txhab ua lag luam zoo tshaj plaws los ntawm tus ntsuj plig ntawm kev nce qib-kev ua siab ncaj thiab kev cia siab.
Thov nco ntsoov tias txawm tias boiler seamless yeeb nkab ua los ntawm cov txheej txheem kub dov, tab sis yog tias koj xav tau cov lus qhia tshwj xeeb thiab cov cuab yeej tshwj xeeb, lawv tuaj yeem ua ntxiv rau cov txheej txheem txias. Feem ntau, cov yeeb nkab txias txias muaj qhov tseeb qhov tseeb thiab qhov chaw tiav, feem ntau yog siv rau cov qauv siv tshuab thiab cov khoom siv hydraulic. Cold dov seamless yeeb nkab tuaj yeem ncav cuag 6mm OD thiab 0.25mm WT.
Vim tias cov txheej txheem txias dov yog kev sib sib zog nqus, yog li yuav muaj nqi ntxiv, tab sis nws tsis txhais hais tias cov yeeb nkab txias txias yog zoo dua li cov yeeb nkab kub kub. Txias dov muaj kev sib sau ceev ceev, thiab qhov taw tes tawm ntawm cov hlau yog tsa vim yog cov yas deformation zoo; Tab sis vim hais tias txias dov seamless raj yog dov hauv qab lub recrystallization kub, yog li yuav muaj ntau residual kev nyuaj siab nyob rau hauv cov yeeb nkab, nws yuav inevitably cuam tshuam cov buckling yam ntxwv ntawm steel tag nrho thiab raws li ib feem.
Lub applciation ntawm txias dov seamless yeeb nkab feem ntau yog siv raws li: qauv yeeb nkab, dej xa yeeb nkab, qis thiab nruab nrab siab boiler yeeb nkab, siab siab boiler yeeb nkab, chiv khoom nrog siab siab yeeb nkab, roj av tawg yeeb nkab, geological drilling yeeb nkab, pob zeb diamond tub ntxhais drilling yeeb nkab, roj drilling yeeb nkab, carbon steel seamless tubing rau nkoj, tsheb ib nrab - qag tes tsho tube seamless raj, siab siab tubing rau diesel xyaw, seamless precision bore hlab rau hydraulic thiab pneumatic thooj voos kheej kheej, txias rub los yog txias dov precision seamless yeeb nkab, seamless stainless hlau raj rau kev tsim kho, seamless stainless hlau raj rau dej thauj thiab hais txog.
Txheej txheem cej luam
Daim ntawv thov
Nws yog tsuas yog siv los ua cov pa roj carbon zoo steel, alloy steel qauv thiab stainless hlau kub-resistant steel seamless steel kav rau kev kub siab thiab siab dua chav boiler kav.
Feem ntau yog siv rau kev kub siab thiab kub kev pab cuam ntawm boiler (Superheater raj, reheater raj, cua qhia raj, lub ntsiab chav tub raj rau siab thiab ultra siab siab boilers). Nyob rau hauv qhov kev txiav txim ntawm kub flue roj thiab dej vapor, lub raj yuav oxidize thiab corrode. Nws yuav tsum tau hais tias cov yeeb nkab steel muaj cov kav ntev, siab tiv thaiv oxidation thiab corrosion, thiab cov qauv zoo.
