Kev tshuaj xyuas cov yeeb nkab hlau

Cov ntaub ntawv siv tau: Haum rau ntau yam hlau kav xws li carbon steel, qis- alloy steel, alloy steel, stainless hlau, duplex steel, aluminium alloy, tooj liab alloy, titanium alloy, npib tsib xee raws alloy, thiab lwm yam.

Cov khoom siv: suav nrog seamless steel kav, welded steel kav, boiler kav, siab hlab ntsha kav, cov kav dej thauj, cov kav dej, cov kav dej, cov kav dej kub, cov roj av casings, cov yeeb nkab fittings, thiab cov kav dej txuas ntxiv.

Cov xwm txheej siv tau: Siv rau kev tshuaj xyuas cov yeeb nkab raw khoom, kev lees paub zoo ntawm lub Hoobkas, kev lees paub tiav engineering, kev tshuaj xyuas tsis tu ncua ntawm - cov kav dej, kev ntsuas kev ua tau zoo, kev soj ntsuam tsis ua haujlwm, thiab kev ntsuas kev txiav txim siab zoo.

Kev tshuaj ntsuam xyuas muaj pes tsawg leeg: kev txiav txim siab ntawm cov ntsiab lus ntawm carbon, silicon, manganese, sulfur, phosphorus, chromium, npib tsib xee, molybdenum, tooj liab, titanium, vanadium thiab lwm yam khoom, thiab kev txiav txim siab ntawm kev sib haum xeeb ntawm cov khoom qib thiab muaj pes tsawg leeg.
Kev ntsuas kev ua haujlwm: chav kub tensile, tawm lub zog, tensile zog, elongation ntawm so, kub tensile, cuam tshuam toughness, Rockwell / Brinell / Vickers hardness, dabtsi yog khoov kev xeem.
Cov txheej txheem kev ua tau zoo: kev sim flattening, expansion test, curling test, bending test, hydraulic test, pneumatic test, sealing test.
Kev tshuaj xyuas metallographic: kev tshuaj xyuas ntawm microstructure, qhov loj me, tsis yog -metallic inclusions, decarburization txheej, banded qauv, weld thiab tshav kub cuam tshuam cheeb tsam qauv.
Kev kuaj tsis muaj kev puas tsuaj: kev kuaj ultrasonic, kev ntsuas tam sim no, X- kuaj kab hluav taws xob, kuaj cov hlau nplaum sib nqus, ntsuas kev nkag mus, siv rau saum npoo, ze ze, thiab kuaj pom qhov tsis xws luag.
Kev tshuaj xyuas qhov loj thiab qhov pom: sab nraud, sab hauv txoj kab uas hla, phab ntsa thickness, ntev, ellipticity, straightness, kawg lub ntsej muag perpendicularity, phab ntsa thickness unevenness, thiab loj kam rau siab soj ntsuam.
Kev tshuaj xyuas qhov zoo: Kev tshuaj xyuas cov kab nrib pleb, quav, kab plaub hau, khawb, xeb, pitting, oxide nplai, weld tsim, thiab cov tsos mob.
Kev ntsuas kev ua haujlwm corrosion: intergranular corrosion, pitting corrosion, kev nyuaj siab corrosion, uniform corrosion, ntsev tsuag corrosion kev ua tau zoo kuaj.
Kev soj ntsuam tsis ua haujlwm: Kev tshuaj xyuas cov qauv tsis ua haujlwm thiab ua rau xws li cov yeeb nkab tawg, corrosion, to, hnav, thiab deformation.
