Lub siab kub boilersteel luj tshib fittingsyog tsim los ntawm high-pressure boiler kav thiab daim hlau
High-pressure thiab siab dua chav boiler steel kav. Cov kav dej boiler no ua haujlwm nyob rau hauv qhov kub thiab txias. Cov yeeb nkab kuj tseem yuav raug oxidized thiab corroded nyob rau hauv qhov kev txiav txim ntawm high-temperature flue gas thiab dej vapor, yog li cov yeeb nkab steel yuav tsum muaj siab durability, siab oxidation tsis kam, thiab lub koom haum zoo stability.
Seamless steel kav rau geological drilling thiab roj drilling tswj; siv cov drilling rigs los tho qhov dej rau kev tshawb fawb ntawm cov pob zeb hauv av, dej hauv av, roj, roj, thiab cov khoom siv ntxhia.
Seamless steel kav rau geological drilling tswj thiab roj drilling yog cov khoom siv tseem ceeb drilling, uas feem ntau suav nrog cov tub ntxhais sab nrauv, cov tub ntxhais sab hauv lub raj, casing, laum yeeb nkab, thiab lwm yam. , cov xwm txheej ua haujlwm yog qhov nyuaj heev. Cov yeeb nkab laum yog raug rau kev ntxhov siab xws li nro, compression, khoov, torsion, thiab tsis sib xws ntawm kev thauj khoom, thiab tseem raug cov av nkos thiab pob zeb hnav. Yog li ntawd, cov khoom siv yeeb nkab yuav tsum tau Nws yuav tsum muaj lub zog txaus, hardness, hnav-tiv taus, thiab cuam tshuam toughness. Cov hlau siv rau cov kav hlau yog qhia los ntawm "DZ" (Geological Suav Pinyin prefix) ntxiv rau tus lej ib los sawv cev rau qhov taw tes tawm ntawm cov hlau. Cov yeeb nkab steel raug xa mus rau hauv lub xeev kub-kho.
Petroleum cracking pipes: seamless pipes for furnace pipes, heat exchanger pipes, and pipelines siv hauv roj av refineries. Feem ntau siv cov pa roj carbon zoo (10, 20), hlau alloy (12CrMo, 15CrMo), cov hlau tsis zoo (12Cr2Mo, 15Cr5Mo), stainless hlau (1Cr18Ni9, 1Cr18Ni9Ti) raug tsim. Ntxiv nrog rau cov ntawv pov thawj tshuaj muaj pes tsawg leeg thiab ntau yam khoom siv ntawm cov yeeb nkab steel, nws tseem tsim nyog los xyuas kom meej cov dej siab, flattening, flaring, thiab lwm yam kev ntsuam xyuas, nrog rau qhov zoo ntawm qhov chaw thiab kev soj ntsuam tsis muaj kev puas tsuaj. Cov yeeb nkab steel yog xa los ntawm kev kho cua sov.
Stainless hlau yeeb nkab: Kub-dov thiab txias-dov stainless hlau kav ntawm ntau yam stainless hlau yog dav siv nyob rau hauv roj av thiab tshuaj cov khoom pipelines thiab stainless hlau yam ntxwv qhov chaw rau ntau yam hom phiaj. Ntxiv nrog rau kev ua kom muaj cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv kho tshuab, lawv tau siv los ua cov kav dej steel uas tuaj yeem tiv taus cov dej siab. Txhawm rau kom ntseeg tau tias cov kev ntsuas dej siab tsim nyog. Txhua yam ntawm cov yeeb nkab steel tshwj xeeb yuav tsum tau lav raws li cov txheej txheem teev tseg.
