Cov khoom lag luam lub npe rau kub-dip galvanized steel kav yog "Kub-dip Galvanized Welded Steel Yeeb Nkab rau Cov Khoom Siv Hluav Taws Xob Tsawg". Nws yog ib yam khoom uas sab hauv thiab sab nrauv ntawm welded steel kav yog galvanized los ntawm cov txheej txheem kub-dip, uas ua rau cov zinc txheej ntawm ob qhov chaw. Qhov no txhim khu kev txhim kho corrosion ntawm cov yeeb nkab steel, kwv yees li 20 npaug ntawm cov kav hlau zoo tib yam. Raws li cov kav xa dej lossis cov qauv hlau, cov kav dej kub-dip galvanized steel yog siv dav hauv kev tsim hluav taws xob, hluav taws xob xa hluav taws xob, kev lag luam roj av, kev tsim kho hydraulic, kev tsim vaj tsev, thiab lwm yam. Cov khoom no ua raws li American Standard ASTM A53, British Standard BS1387, thiab Suav National Standards GB / T3091 thiab GB / T13793. Nws tsis tsim nyog rau qhov chaw uas tsis yog nruab nrab xws li acid, alkali, thiab ntsev.
Technical Requirements rau Pipes:
Qhov saum npoo ntawm cov yeeb nkab kawg mus rau qhov zawj yuav tsum du, tsis muaj concavities, convexities, los yog dov cov cim.
Qhov nruab nrab ntawm qhov zawj yuav tsum yog concentric nrog cov yeeb nkab phab ntsa, thiab qhov zawj qhov dav thiab qhov tob yuav tsum ua tau raws li qhov yuav tsum tau ua.
Qhov zawj tsim ntawm cov khoom siv yeeb nkab los ntawm lub tshuab grooving yuav tsum tsis txhob ua kom puas galvanized txheej ntawm cov yeeb nkab steel.
Hydraulic Test rau Galvanized Yeeb Nkab:
Kev ntsuas hydraulic yuav tsum tau ua ntawm cov kav dej dub. Xwb, eddy tam sim no flaw detection yuav siv tau nyob rau hauv qhov chaw ntawm lub hydraulic xeem. Kev ntsuas siab lossis qhov ntev ntawm qhov ntsuas qhov ntsuas qhov tsis txaus ntseeg tam sim no yuav tsum ua raws li cov kev cai ntawm GB 3092.
Cov khoom siv kho tshuab ntawm cov hlau yog cov cim tseem ceeb rau kev ua kom nws qhov kev ua tau zoo kawg (cov khoom siv tshuab), uas nyob ntawm cov tshuaj muaj pes tsawg leeg thiab kev kho cua sov ntawm cov hlau. Cov txheej txheem steel yeeb nkab qhia ntau yam kev xav tau raws li kev siv, suav nrog cov khoom tensile (lub zog tensile, yield zog los yog yield point, elongation), nrog rau hardness, toughness indicators, thiab high thiab low-temperature khoom xav tau los ntawm cov neeg siv.
Kev ua ntawm Grooves ntawm Galvanized Steel Pipes:
Txiav cov yeeb nkab steel mus rau qhov ntev uas xav tau siv lub tshuab txiav, ua kom muaj kev txiav du.
Teem lub steel yeeb nkab yuav tsum tau ua groove ntawm lub tshuab grooving.
Muab ib theem rau ntawm cov yeeb nkab steel thiab kho nws kom ntseeg tau tias cov yeeb nkab yog kab rov tav.
Nias lub ntsej muag kawg ntawm cov yeeb nkab steel nruj nreem tiv thaiv lub ntsej muag nres ntawm lub tshuab grooving, kom ntseeg tau tias lub hauv paus axis ntawm cov yeeb nkab steel yog perpendicular rau lub ntsej muag nres.
Pib lub tshuab grooving thiab maj mam txo lub jack, tso cai rau lub siab nias lub log kom uniformly yob cov yeeb nkab steel mus rau qhov tob qhov tob ua ntej nres.
Siv lub vernier caliper los xyuas qhov tob thiab qhov dav ntawm qhov zawj. Tom qab paub meej tias lawv ua tau raws li tus qauv yuav tsum tau ua, tshem tawm lub jack thiab tshem tawm cov yeeb nkab steel.
