PE Cov Yeeb Nkab Roj
Kev Taw Qhia Txog PE Gas Pipe
Cov kav dej PE rau roj yog cov kav dej hlau ib txwm muaj thiab cov khoom hloov roj PVC. Cov kav dej roj GKBM PE yog tsim los ntawm cov kab ntau lawm los ntawm Battenfeld-Cincinnati, Lub Tebchaws Yelemees. Cov khoom siv raw yog cov khoom siv tshwj xeeb sib xyaw los ntawm Borealis ME3440 thiab HE3490LS, uas muaj kev ua haujlwm nyab xeeb siab. GKBM tau txais Daim Ntawv Tso Cai Tsim Khoom Siv Tshwj Xeeb ntawm Lub Tebchaws Suav - Cov Khoom Siv Yeeb Nkab Siab uas tau muab los ntawm Lub Chaw Haujlwm Saib Xyuas Kev Zoo, Kev Tshuaj Xyuas thiab Kev Tiv Thaiv ntawm Lub Tebchaws Suav thaum Lub Xya Hli 16, 2012, thiab tau tso cai koom nrog kev tsim cov khoom siv yeeb nkab siab (A2 qib polyethylene kav dej). Daim Ntawv Pov Thawj No.: TS2710W16-2016.
Cov yam ntxwv ntawm PE Gas Pipe
1. Kev ua tau zoo heev: Cov khoom siv tsim khoom siv cov kab tsim khoom qub los ntawm Battenfeld-Cincinnati, Lub Tebchaws Yelemees. Cov khoom siv raw yog cov khoom sib xyaw tshwj xeeb los ntawm Borealis ME3440 thiab HE3490LS. Cov khoom muaj kev nyab xeeb siab.
2. Khoom zoo ruaj khov: Cov khoom siv kuaj rau cov khoom siv raw thiab cov khoom tiav lawm tiav lawm, thiab cov khoom raug tsim thiab tshuaj xyuas raws li GB15558. 1-2003 tus qauv.
3. Kev sib txuas ruaj khov, tsis muaj xau: Cov kav dej txuas nrog los ntawm cov yeeb nkab electrofusion, thiab cov pob qij txha txuas ruaj khov thiab yuav tsis xau.
4. Lub neej ua haujlwm ntev: cov khoom muaj 2-2.5% ntawm cov pa roj carbon dub sib npaug, uas tuaj yeem khaws cia lossis siv sab nraum zoov hauv huab cua qhib rau 50 xyoo; Cov khoom siv inert, tiv taus tshuaj lom neeg zoo, cov tshuaj lom neeg hauv av yuav tsis ua rau muaj kev puas tsuaj rau cov yeeb nkab;
5. Kev tiv thaiv kev ntxhov siab thiab kev hnav tsis zoo: Nws muaj lub zog shear siab, tiv thaiv khawb zoo heev thiab tiv thaiv kev hnav tsis zoo, uas tuaj yeem zam kev puas tsuaj rau lub raj xa dej thaum lub sijhawm tsim kho.
6. Muaj zog tiv taus kev sib haum xeeb ntawm lub hauv paus: Qhov ntev ntawm HDPE cov yeeb nkab dej tawg tshaj 500%, thiab nws muaj kev hloov pauv zoo rau kev sib haum xeeb tsis sib xws ntawm lub hauv paus thiab kev ua tau zoo tiv thaiv av qeeg.
Kev faib tawm ntawm PE Gas Pipe
Muaj tag nrho 72 cov khoom siv roj PE, uas muab faib ua ob hom: PE80 thiab PE100. Raws li qhov siab tshaj plaws uas tso cai ua haujlwm siab, cov khoom raug muab faib ua 4 qib: PN0.5MPa, PN0.3MPa, PN0.7MPa thiab PN0.4MPa. los ntawm dn32- dn400 tag nrho ntawm 18 cov lus qhia, feem ntau yog siv rau hauv kev thauj mus los ntawm roj av.
