Cov yeeb nkab steel ua tiav niaj hnub no, cov khoom siv SCH40 SMLS 5.8M API 5LA106 Qib B, tab tom yuav raug tshuaj xyuas los ntawm tus neeg thib peb xa los ntawm tus neeg siv khoom. Dab tsi yog cov yam ntxwv ntawm qhov kev tshuaj xyuas cov yeeb nkab seamless?
Rau seamless steel kav (SMLS) ua los ntawm API 5LA106 Qib B, nrog rau qhov ntev ntawm 5.8 meters, thiab yuav tsum tau soj ntsuam los ntawm lwm tus neeg sab nrauv, feem ntau yuav tsum tau soj ntsuam hauv qab no:

1. Kev tshuaj xyuas qhov tshwm sim
Deg defects: Xyuas seb puas muaj cov kab nrib pleb, dents, npuas, tev thiab lwm yam tsis xws luag ntawm cov yeeb nkab steel.
Qhov kawg ntawm qhov zoo: Txawm hais tias ob qhov kawg ntawm cov yeeb nkab steel yog tiaj tus, seb puas muaj burrs, thiab seb qhov chaw nres nkoj puas ua raws.
2. Dimension soj ntsuam
Phab ntsa thickness: Siv lub thickness gauge los xyuas cov phab ntsa thickness ntawm cov yeeb nkab steel los xyuas kom meej tias nws ua tau raws li SCH40 phab ntsa thickness specifications yuav tsum tau los ntawm tus qauv.
Sab nraud txoj kab uas hla: Siv lub caliper lossis lwm yam khoom tsim nyog los ntsuas cov kab ntawm cov yeeb nkab steel los xyuas kom meej tias nws ua tau raws li cov qauv tsim.
Ntev: Tshawb xyuas seb qhov ntev ntawm cov yeeb nkab steel puas ua tau raws li tus qauv yuav tsum tau ua ntawm 5.8 meters.
Ovality: Txheeb xyuas qhov sib txawv ntawm qhov sib txawv ntawm cov yeeb nkab steel kom paub meej tias nws ua tau raws li tus qauv.
3. Mechanical Properties Test
Tensile xeem: Tshawb xyuas lub zog tensile thiab tawm lub zog ntawm cov yeeb nkab steel kom paub meej tias nws ua tau raws li qhov yuav tsum tau uaA106 Qib B.
Impact test: Impact toughness test tuaj yeem ua tau raws li qhov xav tau (tshwj xeeb tshaj yog thaum siv nyob rau hauv qhov kub thiab txias).
Hardness test: Surface hardness test yog ua los ntawm hardness tester kom ntseeg tau tias hardness ua tau raws li qhov yuav tsum tau ua.
4. Tshuaj ntsuam xyuas muaj pes tsawg leeg
Tshuaj muaj pes tsawg leeg tsom xam ntawm steel yeeb nkab yog ua los xyuas seb nws muaj pes tsawg leeg ua tau raws li qhov yuav tsum tau muajAPI 5Lthiab A106 Qib B, xws li cov ntsiab lus ntawm carbon, manganese, phosphorus, sulfur thiab lwm yam khoom.
5. Kev ntsuam xyuas tsis muaj kev puas tsuaj (NDT)
Kev kuaj ultrasonic (UT): Xyuas seb puas muaj cov kab nrib pleb, suav nrog thiab lwm yam tsis xws luag hauv cov yeeb nkab steel.
Magnetic particle testing (MT): Siv los txheeb xyuas qhov chaw nyob ze lossis ze ntawm qhov chaw tawg thiab lwm yam tsis xws luag.
Kev kuaj hluav taws xob hluav taws xob (RT): Raws li cov kev cai tshwj xeeb, kev kuaj hluav taws xob tuaj yeem ua tau los kuaj xyuas cov teeb meem sab hauv.
Eddy tam sim no kuaj (ET): Tsis muaj kev puas tsuaj ntawm qhov chaw tsis xws luag, tshwj xeeb tshaj yog cov kab nrib pleb thiab qhov.
6. Hydraulic xeem
Hydraulic sim cov yeeb nkab steel los kuaj nws lub peev xwm ntawm kev sib khi thiab kev sib khi los xyuas seb puas muaj cov dej xau los yog cov qauv tsis xws luag.
7. Kev kos npe thiab ntawv pov thawj
Xyuas seb qhov cim ntawm cov yeeb nkab steel puas yog qhov tseeb thiab raug (nrog rau cov lus qhia tshwj xeeb, cov khoom siv, cov qauv, thiab lwm yam).
Xyuas seb cov ntaub ntawv pov thawj thiab cov ntaub ntawv soj ntsuam puas ua tiav los xyuas kom meej tias cov ntaub ntawv ua tau raws li cov khoom siv tiag tiag.
8. Khoov / flattening xeem
Cov yeeb nkab steel yuav tsum tau khoov lossis flattened los xyuas nws cov yas thiab deformation tsis kam.
Lub koom haum soj ntsuam thib peb xa los ntawm cov neeg siv khoom yuav ua qhov kev tshuaj ntsuam random lossis tshuaj xyuas tag nrho ntawm cov khoom saum toj no kom ntseeg tau tias cov yeeb nkab steel seamless ua tau raws li cov cai ntawm daim ntawv cog lus thiab cov qauv.
