Cov yam ntxwv ntawm cov khoom thiab daim ntawv thov Scope ntawm kev sib txuas yeeb nkab

Cov yam ntxwv ntawm cov khoom thiab daim ntawv thov Scope ntawm kev sib txuas yeeb nkab

1. Nws muaj qhov zoo ntawm qhov hluav taws kub, tiv thaiv corrosion, dej tsis kam, kev laus ua haujlwm, kev ua haujlwm zoo, kev ua haujlwm ruaj khov thiab txhim khu kev qha.

2. Cov yeeb nkab ntev ntev thiab xov loj tuaj yeem ua tiav tshwj xeeb raws li tus neeg siv xav tau. Xws li NPT xov thiab metric xov. Nco tseg: cov xov sab hauv thiab sab nraud yuav tsum tau qhia thaum cov xov specification qhia.

Piv txwv li: bng -700 × G3 / 4 (internal) / G1 (sab nraud) txhais tau hais tias cov roj hmab sheathed saj zawg zog txuas yeeb nkab nrog ib tug ntev ntawm 700, ib kawg ntawm uas yog internal thread G3 / 4 thiab ib kawg ntawm uas yog Sab nraud xov G1.

3. Ua raws li GB3836-2000 thiab iec60079 tus qauv

Scope ntawm kev siv:

1. Nws muaj feem xyuam rau cov chaw muaj kev phom sij hauv cheeb tsam 1 thiab cheeb tsam 2;

2. Muaj feem xyuam rau chav kawm IIa thiab chav kawm IIB explosive gas ib puag ncig;

3. Nws muaj feem xyuam rau thaj tsam 20, 21 thiab 22 ntawm cov plua plav combustible;

4. Muaj feem xyuam rau cov pa roj sib tov kub: T1 ~ T4;

5. Nws yog dav siv rau kev ua hauj lwm thiab teeb pom kev zoo nyob rau hauv qhov chaw muaj kev phom sij xws li kev tshawb nrhiav roj, roj refining, tshuaj lom neeg kev lag luam thiab kev lag luam tub rog, nrog rau cov chaw muaj kev phom sij xws li offshore roj platforms thiab roj tankers.

Nrog rau kev siv cov khoom tawg-pov thawj feem ntau siv tau yooj yim txuas rau hauv qhov chaw txaus ntshai xws li kev tshawb nrhiav roj, roj refining, tshuaj lom neeg kev lag luam thiab kev lag luam tub rog, nrog rau cov chaw txaus ntshai xws li offshore roj channel thiab cov roj tankers, txhawm rau kom ntseeg tau tias cov khoom siv hluav taws xob tsis zoo. ib txwm ua haujlwm ntawm txhua yam khoom siv, ntxiv rau qhov zoo ntawm cov khoom siv nws tus kheej, nws tseem ceeb dua rau cov khoom tawg-pov thawj hloov tau yooj yim txuas raws li cov txheej txheem raug. Tom qab ntawd, dab tsi yuav tsum tau them sai sai rau hauv cov khoom siv thiab yuav ua li cas kom cov cuab yeej zoo dua yuav tsum raug xaiv raws li cov kev xaiv hauv qab no:

1. Ob qhov kawg ntawm qhov tawg-pov thawj hloov tau yooj yim txuas cov yeeb nkab tsis tas yuav tsum tau muab kaw nrog cov khoom siv, thiab ob qhov kawg ntawm lub hose yog nruab nrog tawg-pov thawj cov pob qij txha hloov tau. Lub raj xa dej ntawm cov khoom siv dag zog yog qhov zoo, thiab tag nrho cov ntsiab lus me me uas xav tau kev saib xyuas hauv cov raj xa dej tuaj yeem ua haujlwm zoo. Thaum lub sijhawm cov khoom siv, ob qhov kawg ntawm cov kav dej yuav tsum tau nqa los ntawm tes, thiab tom qab ntawd cov neeg ua haujlwm tsim kho hauv qab ntawm lub tank yuav tsum nqa cov khoom siv. Hauv cov txheej txheem ntawm cov cuab yeej siv, qee yam yuav tsum tau siv, nrog rau cov hlua, drilling rigs, thiab lwm yam.

2. Raws li rau cov khoom siv nrog tawg-pov thawj saj zawg zog txuas yeeb nkab, xyuam xim rau ob qhov kawg ntawm cov xov raws cov kev taw qhia ntawm lwm qhov kawg ntawm cov khoom siv, kom qhov tawg-pov thawj saj zawg zog txuas yeeb nkab yuav tsis xoob ntawm ob qho kawg. ntawm cov cuab yeej siv thaum lub sijhawm ua haujlwm, thiab cov cable tuaj yeem hla tau zoo kawg nkaus.

3. Tom qab tawg-pov thawj kev sib txuas hloov pauv tau muab tso rau hauv cov khoom siv, qhov ntev ntawm cov kav dej yuav tsum tau kho kom haum. Tom qab kev hloov kho, xyuas qhov sib nrug ntawm cov khoom siv thiab cov khoom siv los yog nruab nrab ntawm cov khoom siv thiab cov khoom siv hluav taws xob, thiab sim ua kom lub raj xa dej ntsug kom tsis txhob muaj kev puas tsuaj.
