4000mm diam.

★ Phab ntsa Thickness: Ntau yam ntawm 5mm mus rau 25.4mm, nrog cov kev qhia tshwj xeeb ntawm 6mm thiab 20mm rau feem ntau cov ntawv thov.

★ Ntev: Txheem ntev yog 6m, 12m, thiab 18.5m, nrog rau kev cai ntev muaj raws li qhov yuav tsum tau ua.

★API 5L (PSL1/PSL2): Qib B, X42, X52, X60, X65, X70, mus txog X90, rau cov roj thiab cov kav xa hluav taws xob.

★GB / T 9711: L175, L210, L245, L290, L320, L360, L390, L415, L450, L485, L555, Suav teb chaws tus qauv rau cov kav dej siab.

★ISO 3183: Cov txheej txheem thoob ntiaj teb rau cov kav raj xa dej.

★ASTM A252: GR1, GR2 thiab Gr3, rau cov yeeb nkab yeeb nkab.

★AWWA C200: Rau cov khoom siv dej.

1. General Municipal Water Supply (DN200-DN1000, Siab dua los yog sib npaug rau 1.6MPa):
US Standard: ASTM A53 Gr.B los yog API 5L Gr.B.
European Standard: EN 10217-1 P235TR

2. Ntev -Nyob deb ntawm Dej Kis Kab Kab (DN800-DN2000, Siab 1.6-4.0MPa):
US Standard: API 5L X42 / X52 (PSL2).
European Standard: EN 10217-5 P265GH

3. Cov kav dej haus:
Txawm hais tias siv cov qauv hauv Teb Chaws Asmeskas lossis European, kev kho kev tiv thaiv kev tiv thaiv sab hauv (xws li FBE, cement mortar hauv ob sab phlu) yuav tsum tau, thiab cov khoom siv tiv thaiv corrosion yuav tsum tau ua raws li kev pov thawj dej haus.

4. Cov Khoom Siv Khoom Siv (Kev Siv Khoom Siv, Kev Txhawb Nqa):
US Txuj: ASTM A252 Qib 2/3.
Cov qauv European: EN 10219-1 S355J2H.

Txhawm rau kom ruaj khov nyob rau hauv ib puag ncig hnyav, lawv feem ntau tuaj nrog cov txheej tiv thaiv xws li3 LPE / 3 LPP‌, ‌FBE (Fusion Bonded Epoxy)‌, ‌sab hauv epoxy, thiabPU rwb thaiv tsev​, tshwj xeeb tshaj yog rau hauv av lossis sub- daim ntawv thov dej hiav txwv.

 Txhawm rau kom ntseeg tau thiab ua haujlwm tau zoo, SSAW cov kav dej tau dhau los ntawm kev sim nruj heev thaum lub sijhawm thiab tom qab tsim khoom:

★ Kev Ntsuas Hydrostatic: Txhua lub yeeb nkab yog pressurized nrog dej los xyuas nws lub peev xwm los tiv thaiv cov qib siab uas tsis muaj to.

★ Tsis yog -Kev Ntsuam Xyuas Kev Puas Tsuaj (NDT): Ultrasonic Testing (UT) thiab Radiographic Testing (RT) yog siv los txheeb xyuas cov teeb meem sab hauv thiab saum npoo ntawm cov vuam seam thiab cov yeeb nkab lub cev.

★ Mechanical Testing: Lub zog tensile, lub zog tawm los, thiab kev ntsuam xyuas kev cuam tshuam yog ua los ntawm cov kav dej kom paub meej tias cov khoom siv.

★ Dimensional soj ntsuam: Sab nraud txoj kab uas hla, phab ntsa thickness, thiab ncaj yog ntsuas los xyuas kom meej raws li tus qauv specifications.
