Multi-rifled Seamless Steel Tube

Seamless Multi Rifled Boiler Steel Tubes

Cold-drawn internally threaded steel yeeb nkabyog cov yeeb nkab uas muaj cov qauv xov tshwj xeeb, feem ntau yog siv los txuas nrog lwm cov yeeb nkab fittings, li qub los yog cov khoom siv. Cov yeeb nkab zoo li no muaj cov xov engraved rau sab hauv thiab tuaj yeem txuas tau yooj yim rau lwm qhov chaw nrog cov xov sab nraud, yog li muab kev sib txuas ruaj khov thiab txhim khu kev qha.
Internally threaded steel kav yog dav siv nyob rau hauv ntau yam industries, xws li piping systems, li qub, khoom, thiab lwm yam. Nws muaj zoo heev kev twb kev txuas kev kawm thiab stability. Internally threaded steel round kav kuj tuaj yeem xaiv cov ntaub ntawv sib txawv thiab cov lus qhia tshwj xeeb raws li qhov sib txawv daim ntawv thov scenarios. Piv txwv li, carbon hlau, stainless hlau, hlau alloy, thiab lwm yam yuav siv tau los ua cov hlau threaded hauv cov kav dej kom tau raws li qhov xav tau ntawm qhov chaw sib txawv thiab siv.

Multi-rifled seamless steel raj yog tsim los ua kom tau raws li kev siv kawg, specifications, kam rau ua thiab chemistry.

Seamless Multi Rifled Boiler Steel Tubes

Vuam thiab kev ua cov yeeb nkab hauv threaded
Txoj kev vuam yog ncaj qha dov cov tooj liab rau hauv cov xov thiab tom qab ntawd welding lawv.
Cov txheej txheem ntau lawm yog raws li nram no
High-precision tooj liab strip → xov dov → sib sau thiab vuam → sizing → xov thiab coiling → annealing → ntim.
Lub ntsiab raw khoom ntawm welded yeeb nkab yog TP2 tooj liab sawb. Thaum lub sij hawm ntau lawm, cov tooj liab strips yog welded taub hau mus rau tus Tsov tus tw kom paub meej tias kev ua haujlwm tsis tu ncua ntawm cov kab ntau lawm. Lub sawb tooj liab ua ntej dhau los ntawm cov txheej txheem xov dov, thiab cov xov tooj sib txawv ntawm embossing rollers raug xaiv raws li cov duab ntawm cov xov.
Lub sawb tooj liab nias los ntawm cov xov yog tsim los ntawm ob peb txoj kev chais thiab ces high-frequency welded. Txhawm rau kom ntseeg tau tias qhov sib xws thiab qhov loj ntawm cov yeeb nkab txoj kab uas hla, tom qab vuam, cov burrs sab nraud yog thawj zaug tshem tawm nrog lub scraper, thiab tom qab ntawd cov kab uas hla yog txiav txim siab los ntawm cov sizing cov menyuam los xyuas kom meej tias lub inch sab nraud thiab ovality ntawm cov yeeb nkab ua tau raws li cov txheej txheem. kev xav tau.

Internally threaded pipes tseem hu ua cov kav dej qhuav, cov kav dej sab hauv lossis cov kav dej hauv finned. Nyob rau hauv nruab nrab cua txias, nws yog tsuas yog siv nyob rau hauv qhuav evaporators. Thaum tshav kub kub pauv, cov tub yees sab nraum lub raj yog txias los ntawm evaporation thiab nthuav dav ntawm cov tub yees hauv lub raj. Nws kuj yog siv nyob rau hauv tsev thiab ua lag luam cua txias cua sov exchangers los yog nyob rau hauv high kub kav. Lub cheeb tsam sab hauv ntawm ib chav tsev ntev ntawm cov kav hlau txuas sab hauv yog 1.5 mus rau 2 npaug ntawm cov kav dej zoo tib yam, thiab nws cov coefficient hloov hluav taws xob yog 1.5 mus rau 2.4 npaug ntawm cov kav dej tooj liab zoo tib yam. Kev khiav hauj lwm ntawm cov cab kuj tsuas yog nce los ntawm 3-5%, uas tuaj yeem txuag tau 20-35% ntawm lub zog, thiab qhov hnyav ntawm tag nrho cov tub yees cua txias yog txo los ntawm 10-25%.
