Ob leegweldedthiabseamless steel kavtau txais kev soj ntsuam nruj thiab tshuaj xyuas ua ntej lawv tawm hauv lub hoobkas.
Kab lus no tshawb nrhiav seb manufacturers nyiam li casHuayang steel yeeb nkabxyuas kom txhua cov yeeb nkab ua tau raws li cov qauv thoob ntiaj teb los ntawm kev sib xyaw ua kekev kuaj tshuab, tsis yog - kev tshuaj xyuas kev puas tsuaj, thiab kev tswj cov txheej txheem nruj.
Yog tias koj txaus siab nkag siab txog cov txheej txheem thiab daim ntawv thov sib txawv ntawm cov kav dej welded thiab seamless, mus saib peb lub ntsiab lus:Welded vs. Seamless Steel Pipe - Nkag siab txog qhov sib txawv tseem ceeb thiab kev siv.
Koj tseem tuaj yeem tshuaj xyuas qhov kev tsim khoom hauv peb cov lus qhia muaj feem xyuam:Welded Steel Pipe - Hom, Chaw Tsim Khoom, thiab Kev Siv Khoom Siv.
Qhov tseem ceeb ntawm Kev Tswj Xyuas Zoo hauv Steel Pipe Production
Kev tswj kom zoo hauv cov yeeb nkab tsim kom ntseeg tau tias txhua yam khoom tuaj yeem tiv taus nws lub siab, kub, thiab ib puag ncig.
Ib qho tsis xws luag - txawm tias microscopic - tuaj yeem ua rau cov dej xau, tawg, lossis lub cev tsis ua haujlwm, tshwj xeeb hauvroj & roj, tsim hluav taws xob, thiab kev thauj mus los siab -daim ntawv thov.
RauHuayang steel yeeb nkab, kev ruaj ntseg zoo pib los ntawm kev tshuaj xyuas cov khoom siv raw mus rau qhov kawg khoom xa tuaj, npog dhau30 cais cov txheej txheem kuaj thiab pov thawj.
Kev soj ntsuam cov txheej txheem rau Welded Steel Pipes
Kev tsim khoom ntawmERW, LSAW, thiab SSAW kavincludes specialized testing protocols tailored to detect issues in the weld seam, body, and coating.
1. Kev tshuaj xyuas qhov pom thiab qhov ntev
Txhua cov yeeb nkab raug tshuaj xyuas qhov pom ntawm qhov tsis xws luag xws li dents, undercuts, lossis tsis tiav fusion. Dimensional raug (sab nraud txoj kab uas hla, phab ntsa thickness, ovality, thiab straightness) yog ntsuas siv cov gauges.
| Parameter | Kev kam rau siab (API 5L / ASTM) | Txoj kev tshuaj xyuas |
|---|---|---|
| Sab nraud | ± 0.5% ntawm nominal loj | Digital caliper, OD gauge |
| Phab ntsa Thickness | ±10% | Ultrasonic thickness meter |
| Kev ncaj | Tsawg dua lossis sib npaug li 0.2% ntawm qhov ntev | Kev ntsuas qhov ncaj |
| Kev npaj kawg | ± 1 hli | Visual check & bevel gauge |
2. Tsis yog -Kev Ntsuam Xyuas Kev Puas Tsuaj (NDT)
Weld seams thiab yeeb nkab lub cev raug kuaj xyuas sivultrasonic (UT)los yogX-Kev kuaj kab hluav taws xob (RT)los xyuas kom meej weld kev ncaj ncees thiab xyuas cov flaws sab hauv.
- ERW cev: Kev tshuaj xyuas tsis tu ncua ultrasonic hla txoj kab vuam.
- LSAW/SSAW pipes: Tag nrho- lub cev ultrasonic thiab radiographic kuaj tom qab vuam.
3. Kev Ntsuas Hydrostatic
Txhua lub yeeb nkab yog ntim nrog dej thiab nias rau tus nqi siab dua nws cov kev khiav hauj lwm siab (feem ntau 70-100% siab dua). Qhov no ua kom tsis muaj qhov tawg lossis deformation tshwm sim.
4. Kev ntsuam xyuas flattening thiab dabtsi yog khoov
Cov kev ntsuam xyuas no ntsuas cov yeeb nkab lub peev xwm los deform nyob rau hauv load yam tsis muaj cracking - tseem ceeb rau kev thauj mus los thiab installation durability.
5. Txheej thiab Surface Surface
Cov kav dej uas tiv thaiv -corrosion txheej xws li3PE, FBE, lossis galvanizationundergo adhesion, thickness, thiab cov hnub caiv kuaj kom lav qhov kev ncaj ncees.
Kev soj ntsuam cov txheej txheem rau Seamless Steel Pipes
Txij li cov kav dej seamless tsim tsis muaj vuam, kev ntsuam xyuas tsom ntau duakhoom homogeneity, nto smoothness, thiab mechanical kev ua tau zoo.
1. Eddy Tam sim no thiab Ultrasonic kuaj
NDT txuas ntxiv kuaj pom qhov chaw thiab subsurface defects xws li suav nrog lossis tawg.
2. Tensile thiab Hardness Tests
Cov qauv raug coj los ntawm txhua pawg los ntsuastensile zog, yield zog, thiabelongation tus nqi- cov cim tseem ceeb ntawm cov khoom toughness thiab ductility.
| Mechanical Property (Tus nqi zoo) | Seamless yeeb nkab (ASTM A106 Gr. B) | Welded yeeb nkab (ASTM A53 Gr. B) |
|---|---|---|
| Tensile zog (MPa) | 415 | 415 |
| Yield zog (MPa) | 240 | 240 |
| Elongation (%) | 30 | 25 |
| Impact Resistance | Zoo heev | Nruab nrab |
| Kev ntsuas siab | Siab | Nruab nrab |
3. Kev Ntsuas Hydrostatic thiab Pneumatic
Zoo ib yam li cov kav dej welded, cov kav dej seamless yog siab- kuaj kom ntseeg tau tias tsis muaj pinholes lossis qhov chaw tsis muaj zog uas tuaj yeem ua rau muaj kev ntxhov siab.
Chemical thiab Mechanical Property Verification
Ua ntej ntau lawm txawm pib, txhua batch ntawm steel siv nyob rau hauv cov yeeb nkab manufacturing yog raug tshuaj ntsuam xyuas. Cov txiaj ntsig tau txiav txim siab seb cov hlau puas ua tau raws li cov qauv kev txwv tsis pub dhauAPI, ASTM, lossis EN.
| Element | Tsawg Carbon Steel (Hloov ntau yam) | Medium Carbon Steel (Hloov ntau yam) |
|---|---|---|
| Cov pa roj carbon (C) | 0.10–0.25% | 0.25–0.50% |
| Manganese (Mn) | 0.25–1.00% | 0.60–1.65% |
| Phosphorus (P) | Tsawg dua lossis sib npaug li 0.035% | Tsawg dua lossis sib npaug li 0.035% |
| Sulfur (S) | Tsawg dua lossis sib npaug li 0.035% | Tsawg dua lossis sib npaug li 0.035% |
Kev ntsuam xyuas cov cuab yeej cuab tam kom ua raws li lub zog thiab cov qauv ductility, tiv thaiv cov yeeb nkab tsis ua hauj lwm ntxov hauv qhov chaw hnyav.
