TS EN 10297yog qhov tseeb European tus qauv hu ua:
"Seamless thiab welded steel raj rau txhua yam thiab siab lub hom phiaj - Kev xa khoom"
Nws npogseamless thiab welded (xws li longitudinal submerged arc welded, tab sis feem ntau tsis muab kauv welded)raj rau mechanical engineering, cov cuab yeej siv siab, thiab kev siv cov qauv,feem ntau tsis yog rau cov kav dej.
RauSpiral Submerged Arc Vuam (SSAW / HSAW) Pipes, cov qauv tsim nyog yog:
Thawj Cov Qauv rau SSAW Pipes:
TS EN 10208 -2: Cov kav dej hlau rau cov kav dej rau cov kua dej uas muaj hluav taws xob - Ntu 2: Cov kav dej yuav tsum tau ua hauv chav B
Qhov no yog lub ntsiab European qauv rau welded kav (xws li kauv welded) rau roj thiab roj kis tau tus mob. Nws qhia meej txog cov kev xav tau rau cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, kev sim (NDT, hydrostatic), thiab qhov ntev. Cov kav dej tau muab cais (Class 1, 2, 3) raws li kev pabcuam (xws li kev pabcuam qaub).
API Specification 5L: Kab Yeeb
Cov txheej txheem kev lag luam thoob ntiaj teb los ntawm American Petroleum Institute. Nws feem ntau npog SSAW kav (tsim raws li HSAW). Nws suav nrog qib B, X42 txog X100, nrog rau cov kev xav tau dav dav rau kev tsim khoom, kuaj, thiab tshuaj xyuas.
TS EN ISO 3183 Kev lag luam roj av thiab roj ntuj - Kev lag luam roj av thiab ntuj tsim - Cov yeeb nkab steel rau kev thauj mus los hauv cov kav dej
Cov txheej txheem thoob ntiaj teb ua raws li API 5L thiab EN 10208 cov qauv.
Cov yam ntxwv tseem ceeb ntawm SSAW Pipes rau Cov Qauv no:
Kev tsim khoom:Tsim los ntawm spirally winding ib kub - dov steel coil (skelp) thiab vuam cov seam sab hauv thiab sab nraud siv submerged arc vuam (SAW).
Qhov ntau thiab tsawg:Loj diameters (feem ntau los ntawm 20 "mus txog 100" los yog ntau tshaj) nrog ntau yam ntawm phab ntsa thicknesses.
Cov ntawv thov tseem ceeb:Ntev -nyob deb ntawm ntug dej hiav txwv thiab ntug dej hiav txwv roj & roj xa mus, cov kav dej, cov kav dej, thiab kev siv cov qauv.
Cov lus sib piv: Pipeline- Cov Qauv Txheej Txheem rau SSAW Pipes

Vim li cas EN 10297 txawv:
TS EN 10297-1npogseamlesssteel tubes rau mechanical thiab siab lub hom phiaj.
TS EN 10297-2npogweldedsteel hlab, tab sis qhov no feem ntau yog hais txoglongitudinal weldedcov txheej txheem (xws li ERW lossis longitudinal SAW),tsis yog cov txheej txheem kauv welded. Nws daim ntawv thov yog rau boilers, tshav kub exchangers, thiab general mechanical engineering,tsis loj - txoj kab uas hla xa mus.

Yog koj nug txogKauv Submerged Arc Welded (SSAW) Pipesrau daim ntawv thov pipeline, cov qauv tsim nyog rau kev siv yog:
TS EN 10208-2(European tej yaam num)
API 5L(Global Oil & Gas Project)
TS EN ISO 3183(International tej yaam num)
Rau SSAW cov kav dej hauv cov txheej txheem lossis cov ntawv thov, cov qauv zoo liTS EN 10219(txias-ua welded structural hollow seem) los yogASTM A252, ASTM A252(rau piling) tej zaum yuav siv tau, tab sis cov no tsis yog cov qauv siab yeeb nkab.
Yog tias koj xav tau cov ntaub ntawv ntxaws ntxaws rau SSAW cov kav dej raws li EN 10208 lossis API 5L, thov qhia rau kuv paub, thiab kuv tuaj yeem muab cov ntaub ntawv tshwj xeeb.
