Cov yeeb nkab hlau alloy feem ntau yog siv rau hauv cov chaw tsim hluav taws xob, chaw tsim hluav taws xob nuclear, lub boiler siab, lub tshuab cua sov kub siab, lub tshuab cua sov rov ua dua thiab lwm yam yeeb nkab siab thiab kub siab thiab cov khoom siv. Nws yog ua los ntawm cov hlau carbon zoo, cov hlau alloy thiab cov hlau stainless uas tiv taus kub los ntawm kev dov kub (extrusion, expansion) lossis dov txias (kos duab).
Cov yeeb nkab hlau thiab cov yeeb nkab seamless muaj kev sib txuas thiab qhov sib txawv, tsis tuaj yeem tsis meej pem. Cov yeeb nkab kub yog txhais tias yog cov yeeb nkab hlau raws li cov khoom siv tsim khoom (piv txwv li, cov khoom siv). Raws li lub npe qhia, nws yog cov raj ua los ntawm cov hlau sib xyaw. Cov yeeb nkab seamless yog txhais tias yog cov yeeb nkab hlau (seam thiab seamless) raws li cov txheej txheem tsim khoom.
Cov yeeb nkab hlau yog ib hom yeeb nkab hlau tsis muaj seamless, uas muab faib ua cov yeeb nkab hlau tsis muaj seamless thiab cov yeeb nkab hlau uas tiv taus cua sov siab. Feem ntau txawv ntawm cov qauv tsim khoom thiab kev lag luam ntawm cov yeeb nkab hlau, cov yeeb nkab hlau annealed thiab tempered hloov cov khoom siv kho tshuab. Ua tau raws li cov xwm txheej ua tiav. Nws qhov kev ua tau zoo dua li cov yeeb nkab hlau tsis muaj seamless, cov tshuaj lom neeg muaj ntau Cr, yog li nws muaj kev tiv taus kub siab, tiv taus kub qis thiab tiv taus corrosion. Cov yeeb nkab carbon seamless feem ntau tsis muaj cov khoom sib xyaw lossis muaj me ntsis ntawm cov khoom sib xyaw. Cov yeeb nkab hlau yog siv dav hauv roj av, aerospace, tshuaj lom neeg, hluav taws xob, boiler, tub rog thiab lwm yam lag luam, vim tias cov khoom siv kho tshuab ntawm cov yeeb nkab hlau yog hloov pauv thiab yooj yim kho.

2, cov yeeb nkab hlau tsis muaj seamless rau kev thauj mus los kua (GB / T8163-2008) yog siv rau kev thauj mus los ntawm dej, roj, roj thiab lwm yam kua ntawm cov yeeb nkab hlau tsis muaj seamless.

3, qis thiab nruab nrab siab boiler seamless hlau raj (GB3087-2008) yog siv los tsim ntau yam qauv ntawm cov kav dej kub thiab nruab nrab siab boiler superheated steam, kav dej npau thiab locomotive boiler superheated steam thiab kav dej arch cib ntawm cov hlau zoo carbon kub dov thiab txias kos (dov) seamless steel raj.

4, siab siab boiler seamless hlau raj (GB5310-2008) yog siv rau kev tsim cov raj dej siab thiab siab dua qhov siab boiler cua sov nto nrog cov hlau carbon zoo, hlau alloy thiab stainless hlau tiv taus cua sov seamless steel raj.

5, cov khoom siv chiv tshuaj rau cov yeeb nkab hlau siab siab (GB6479-2000) yog tsim rau qhov kub ua haujlwm ntawm -40 ~ 400 ℃, ua haujlwm siab ntawm 10 ~ 30 Ma cov khoom siv tshuaj lom neeg thiab cov kav dej ntawm cov hlau zoo carbon thiab cov hlau alloy seamless steel yeeb nkab.

6, roj av tawg seamless steel yeeb nkab (GB9948-2006) yog tsim rau roj av refinery cub tawg raj, cua sov exchanger thiab pipeline seamless steel yeeb nkab.
