PE fais fab fusion fittings muaj ntau yam kev siv xws li roj thiab dej fittings. Thaum muas ntau PE hluav taws xob fusion fittings, cov neeg siv tsuas yog yuav tsum tau txiav txim siab cov kev ntsuas hauv qab no.
1: Kev tshwm sim
Sab hauv thiab sab nraud ntawm PE fais fab fusion fittings yuav tsum huv si thiab du, tsis muaj shrinkage voids, pom tseeb indentations los yog xim tsis sib xws. Ob qhov kawg ntawm PE hluav taws xob fusion fittings yuav tsum tau txiav tiaj tus thiab perpendicular mus rau axis ntawm cov yeeb nkab. Tsim nyog PE hluav taws xob fusion fittings yuav tsum ua tau raws li qhov yuav tsum tau ua.
2: Loj
Qhov loj ntawm PE hluav taws xob fusion yeeb nkab fittings yuav tsum ua raws li qhov yuav tsum tau ua ntawm GB / T1336.3-2018, thiab qhov loj me yuav tsum tsis txhob muaj qhov yuam kev ntau tshaj 0.1 millimeters.
3: Oxidation degree
Muaj ib txoj haujlwm tshaj lij hu ua oxidation induction lub sijhawm rau oxidation degree ntawm PE hluav taws xob fusion yeeb nkab fittings. Lub sijhawm oxidation yuav tsum tsis pub tsawg tshaj 20 feeb, thiab qhov kub tseem ceeb rau oxidation yuav tsum tsis pub dhau 200 degrees.
4: Cov ntsiab lus tshauv
Cov hmoov tshauv ntawm PE hluav taws xob fusion fittings yuav tsum ua raws li GB/T9345 tus qauv.
5: Hydraulic zog
Lub zog zoo li qub hydraulic ntawm PE hluav taws xob fusion yeeb nkab fittings muab faib ua ob tus qauv raws li qhov kub thiab txias. Thaum qhov kub ntawm 20 ° C thiab 70 ° C, lub sij hawm tsis ua hauj lwm yog ntau tshaj 100 teev, thiab tsis muaj kev puas tsuaj los yog tawg, lub zog tsim nyog. Thaum tus nqi kub siab tshaj 80 degrees. Lub sijhawm ntawm kev puas tsuaj yuav tsum ntau dua 1000 teev, thiab yuav tsum tsis txhob muaj kev puas tsuaj. kuv to.
6: Tensile zog
Lub tensile toughness ntawm PE hluav taws xob fusion yeeb nkab fittings yuav tsum tau kuaj kom txog thaum lub toughness puas lawm. Thaum xaiv, cov qauv tshuaj ntsuam xyuas yuav tsum tau tsim nyob rau saum npoo ntawm cov khoom, feem ntau GB / T19810 series execution qauv.
