Niaj hnub no peb qhia cov khoom siv roj seamless steel yeeb nkab, roj yeeb nkab (GB9948-88) yog tsim rau roj refinery rauv tube, kub exchanger thiab seamless yeeb nkab.

Hlau yeeb nkab rau geological drilling (YB235-70) yog siv rau cov tub ntxhais drilling los ntawm geological department, uas yuav muab faib ua laum yeeb nkab, laum dab tshos, tub ntxhais yeeb nkab, casing yeeb nkab thiab nag lossis daus yeeb nkab raws li nws siv.

Roj yeeb nkab yog ib hom hlau ntev nrog hollow seem thiab tsis muaj kev sib koom ua ke nyob ib puag ncig, thaum roj av tawg yeeb nkab yog hom kev lag luam hlau.
API: Nws yog Lub Tsev Kawm Ntawv Askiv American Petroleum, Suav lub ntsiab lus rau American Petroleum Institute.

OCTG: Nws yog lub ntsiab lus ntawm Roj Lub Tebchaws Tubular Cov Khoom Siv, uas txhais tau hais tias Roj tshwj xeeb cov yeeb nkab hauv Suav teb, suav nrog cov roj ua tiav, cov yeeb nkab laum, laum dab tshos, dab tshos, thiab luv luv, thiab lwm yam.

Tubing: Ib cov yeeb nkab siv rau hauv cov roj thiab roj, kev txhaj tshuaj dej, thiab cov kua qaub tawg hauv qhov dej.

Casing: Ib lub yeeb nkab khiav ntawm qhov chaw ntawm lub ntiaj teb mus rau hauv ib lub qhov zoo-drilled li hauv ob sab phlu los tiv thaiv phab ntsa ntawm kev sib tsoo.

Laum yeeb nkab: cov yeeb nkab siv los laum qhov.

Yeeb Nkab: Cov yeeb nkab siv rau kev xa cov roj thiab roj.

dab tshos: ib lub tog raj kheej nrog cov xov sab hauv siv los txuas ob txoj hlua txuas.

Coupling khoom: yeeb nkab siv los ua coupling.

API threads: yeeb nkab threads teev nyob rau hauv API 5B, nrog rau cov yeeb nkab round threads, luv round yeeb nkab threads, ntev round yeeb nkab threads, offset trapezoidal yeeb nkab threads, pipeline yeeb nkab threads, thiab lwm yam.

Cov xov tshwj xeeb: tsis yog API xov hom nrog tshwj xeeb sealing, sib koom thiab lwm yam khoom.

Kev ua tsis tiav: poob ntawm qhov qub ua haujlwm vim deformation, tawg thiab nto puas tsuaj nyob rau hauv cov kev pabcuam tshwj xeeb. Cov ntaub ntawv tseem ceeb ntawm casing tsis ua hauj lwm yog: extrusion, plam, rupture, to, corrosion, bonding, hnav thiab lwm yam.
