Steel raj yog cov khoom siv ntau heev hauv kev tsim kho thiab tsim khoom. Nws yog siv rau ntau yam kev siv, nrog rau cov tsev, txuas hniav, tsheb, thiab tshuab. Tab sis dab tsi raws nraim yog steel raj hu ua? Hauv tsab xov xwm no, peb yuav tshawb xyuas cov npe sib txawv rau cov raj steel thiab ntau hom steel raj muaj.
Hom Hlau Tubes
Muaj ntau ntau hom steel tube, txhua tus muaj nws tus yam ntxwv thiab kev siv. Qee yam ntawm cov yeeb nkab steel feem ntau muaj xws li:
1. Seamless Steel Tubes - Seamless steel tubes yog tsim los ntawm ib daim hlau, tsis muaj seam lossis pob qij txha. Lawv muaj zog heev thiab feem ntau siv rau hauv cov ntawv thov siab, xws li hauv boilers thiab roj refineries.
2. Welded Steel Tubes - Welded steel tubes yog tsim los ntawm vuam ob peb daim hlau ua ke. Lawv tsis tshua kim tshaj seamless steel raj, tab sis tsis muaj zog li.
3. Galvanized Steel Tubes - Galvanized steel hlab yog coated nrog ib txheej ntawm zinc, uas pab tiv thaiv cov hlau los ntawm corrosion. Lawv feem ntau siv rau sab nraum zoov siv, xws li hauv fencing thiab guardrails.
4. Stainless Hlau Tubes - Stainless hlau raj yog tsim los ntawm ib hom hlau uas muaj chromium, uas ua rau lawv zoo heev tiv thaiv corrosion. Lawv feem ntau siv hauv kev ua zaub mov thiab kev siv kho mob.
5. Carbon Steel Tubes - Cov pa roj carbon steel yog tsim los ntawm ib hom hlau uas muaj cov pa roj carbon. Lawv muaj zog thiab ruaj khov, tab sis tsis muaj zog tiv thaiv corrosion li stainless hlau raj.
Lub npe rau Steel Tube
Thaum lub raj steel yog nws lub npe nrov tshaj plaws, muaj ntau lub npe siv los xa mus rau cov khoom siv no. Qee qhov no suav nrog:
1. Cov yeeb nkab steel - cov yeeb nkab steel yog lwm lub npe rau cov yeeb nkab steel. Lub sij hawm cov yeeb nkab feem ntau siv thaum xa mus rau cov kab hlau loj dua, xws li cov khoom siv thauj khoom.
2. Hollow Structural Section - Hollow structural section (HSS) yog ib lo lus siv los piav txog ib hom steel tube uas yog square, rectangular, los yog voj voog. Cov raj no feem ntau siv rau hauv kev tsim kho, vim lawv muaj zog thiab hnav.
3. Tube & Yeeb Nkab - Tube thiab yeeb nkab yog ib lo lus siv los piav txog ob lub raj steel thiab cov kav hlau. Lo lus feem ntau yog siv nyob rau hauv kev lag luam kev lag luam, qhov twg ob lub raj thiab cov kav dej feem ntau siv.
4. Round Tube - Round tube yog ib lo lus siv los piav txog cov raj hlau uas muaj lub voj voog zoo. Cov raj no feem ntau siv hauv kev tsim khoom thiab kev tsim kho.
5. Square Tube - Square tube yog ib lo lus siv los piav txog cov raj steel uas yog square lossis duab plaub. Cov raj no feem ntau siv hauv kev tsim kho, vim lawv muaj zog heev thiab tuaj yeem txhawb nqa hnyav.
Daim ntawv thov rau Steel Tubes
Cov raj steel yog siv rau ntau yam kev siv, suav nrog:
1. Kev tsim kho - cov raj steel feem ntau yog siv rau hauv kev tsim kho, tshwj xeeb tshaj yog nyob rau hauv lub tsev thav duab thiab cov qauv kev txhawb nqa.
2. Kev tsim khoom - Cov raj steel feem ntau siv hauv kev tsim khoom, raws li lawv tuaj yeem ua tau yooj yim zoo li tus thiab tsim rau hauv ntau hom duab thiab ntau thiab tsawg.
3. Kev thauj mus los - cov raj steel feem ntau yog siv rau hauv kev thauj mus los, xws li hauv tsheb thiab tsheb kauj vab.
4. Lub zog - cov raj steel yog siv rau hauv kev lag luam hluav taws xob, tshwj xeeb tshaj yog nyob rau hauv cov roj thiab cov kav dej.
5. Infrastructure - steel raj feem ntau yog siv rau hauv kev siv infrastructure, xws li nyob rau hauv cov choj thiab qhov tunnels.
Xaus
Raws li peb tau pom, steel tube muaj ntau lub npe sib txawv thiab tuaj nyob rau hauv ntau hom sib txawv. Nws yog cov khoom siv ntau yam uas siv rau hauv ntau yam kev siv, los ntawm kev tsim kho mus rau kev tsim khoom mus rau kev thauj mus los. Txawm hais tias koj hu nws lub raj steel, steel yeeb nkab, lossis lwm yam tag nrho, tsis muaj qhov tsis lees paub lub luag haujlwm tseem ceeb uas cov khoom siv no ua hauv peb lub ntiaj teb.
