Ibipimo byo kurangiza imiyoboro yashyizwe kumurongo bya Polyurethane mu Bushinwa Ibikoresho by'Ubushinwa, inzira, imikorere, no gupima inzira zose . sisitemu yihariye ni izi zikurikira:
I. ibipimo byigihugu byigihugu
GB / T29047-2012
Iri somo rishyiraho ibisobanuro byihariye bya polyurethane, birambuye ibisabwa byimiterere ya polyethylene yo hanze na polyurethane ya polyethane yashyinguye imiyoboro ya plastiki .}}}}}}}}}}}}}}}}}}}} ibipimo byingenzi birimo:
Isuku yubucucike burenze cyangwa bungana na 60 kg / m³, igipimo cyagutse kirenze cyangwa kingana na 88%, bingana na 0.033 w / (milen 50);
Imyenda yo hanze irenze cyangwa ingana na 950 kg / m³, imbaraga za tensile zirenze cyangwa zingana na 19 mp .
Irakoreshwa kumuyoboro wo gushyushya hamwe ninganda zinganda .
GB / T29046-2012
Yibanda ku buryo bwo gupima, kwerekana inzira zo kwinginga mu bunini, ibizamini byo mu kirere, bisaba kugenzura ubushyuhe burenze cyangwa bingana na 88%
2. Igishushanyo mbonera hamwe nibikoresho
Ibikorwa byumuryango ibisabwa
Umuyoboro wakazi: Imiyoboro ya DN800 igomba gukoresha imiyoboro isukuye ya Q235B (SY / T {2} {2} {{4} {4 {
Ikibanza cyo kwinginza: Ubwinshi bwa Polyurethane burenze cyangwa bungana na 55 kg / m³ igipimo cyigihugu cya silicon busabwe ku buryo bukabije, ubunini bwa silicon busabwa ku buryo bukabije, ubunini bwa silicon busabwa ku buryo bukabije, ubunini bwa silicon busabwa ku buryo bukabije, ubugari bwa mm (bwahinduwe bushingiye ku mirimo);
Ouser Ciser: CDPE Ouseur Oader igomba gutsinda ikizamini 15 cya KV
Ibipimo bidasanzwe byo kurwanya imihindagurikire y'ikirere
Umurima wa peteroli / gaze: Imiyoboro ikora igomba kubahiriza GB / t {{0}9711-2017 (gisanzwe kuri spiral Seam yarengeje imiyoboro ya arc isusurutse ibyuma);
High-Temperature Pipes (>Impamyabumenyi 140): Koresha inyubako zo hanze yinyuma, hamwe nicyuma cya gari ya gahoro kaseti kurenza cyangwa bingana na 0 {{3.}}}} 5 mm.
3. Gahunda yumusaruro no kwemerwa
Ibihe byabanjirije Fabrication Ibisobanuro
Uburebure busanzwe bwibice byabanjirije ibisimba bifite metero 12 kuri buri gice, hamwe na mm ya mm 200 gusudira byabitswe kumurongo;
Umuvuduko mwinshi wo kubara ugenzura urumogi <0 {{3 {}} 5%, intangarugero igice kirenze cyangwa kingana na 0.5 mm.
Kugenzura no kwemerwa
Hanze yinyuma yo kwihanganira ± 0.2 MM, igihombo cyubushyuhe kuri kilometero kirenze cyangwa kingana na 2% (ubushyuhe bwamazi burenze cyangwa bungana na dogere 140);
Ikizamini cya gatatu kigomba kugenzura imishinga yubushyuhe (munsi ya cyangwa ingana na 0.033 w / (M · k)) nigipimo cyakagari (kirenze 90% kubikorwa byinshi);
Imiyoboro-yubushyuhe igomba gutanga raporo yigihe gito cyo kurwanya ubushyuhe kugeza kurwego rwo hejuru kugeza kuri 300 .
4. Inganda zifasha inganda
Cj / t {{0}
Amahame yinyongera kumuyoboro wizewe hamwe nubushyuhe bwo hagati butari munsi cyangwa bingana na dogere 120, byerekana ibisabwa kugirango ukore urukuta rwibyuma no kubasuhuza
En 253
Ahuza ibipimo mpuzamahanga, bikwiranye nubutaka bwumurongo wubutaka bwahujwe na sisitemu ya pre-fabriciciation .
Binyuze muri sisitemu isanzwe, imiyoboro ya polyurethane igera kuri gahunda yuzuye igenzura ibikoresho byo gutoranya ibintu, kwemeza kwizerwa no kuramba mu bihe bigoye .
