Icyuma gisobekeranye umurongo wa PE Umuyoboro wa gaze

Ibisobanuro bigufi:

Umuyoboro usobekeranye wa polyethylene umuyoboro wogukora bikozwe mubyuma bikonje bikonje bikonje hamwe na thermoplastique nkibikoresho fatizo, kandi imiyoboro yicyuma yoroheje yometseho ibyuma ikozwe na argon arc butt welding cyangwa plasma spiral welding ikoreshwa nkibishimangira. Ibice by'inyuma n'imbere ni impande zombi zigizwe na thermoplastique.

Umuyoboro usobekeranye wa polyethylene umuyoboro wogukora bikozwe mubyuma bikonje bikonje bikonje hamwe na thermoplastique nkibikoresho fatizo, kandi imiyoboro yicyuma yoroheje yometseho ibyuma ikozwe na argon arc butt welding cyangwa plasma spiral welding ikoreshwa nkibishimangira. Ibice by'inyuma n'imbere ni impande zombi zigizwe na thermoplastique. Ubwoko bushya bwumuyoboro wumuvuduko, Kuberako imbaraga zicyuma zometseho ibyuma byiziritse zipfunyitse muri thermoplastique ikomeza, uyu muyoboro uhuriweho ntushobora gutsinda gusa ibitagenda neza byimiyoboro yicyuma nu miyoboro ya pulasitike, ariko kandi ufite ubukana bwimiyoboro yicyuma na ruswa. kurwanya imiyoboro ya pulasitike. Ni igisubizo cyinganda za peteroli ninganda. Numuyoboro ukenewe byihutirwa byimiyoboro nini nini ya diametre ikomeye mu miti ya farumasi, ibiryo, ubucukuzi, gaze nindi mirima. Nibikorwa byubuhinduzi bwa tekinoloji yo gukemura umuyoboro wingenzi wubwubatsi nogutanga amazi ya komini. Nubwoko bushya bwumuyoboro uhuriweho muri 21stikinyejana.

Ibiranga

Imikorere yisuku
Ibipimo by’isuku n’umutekano by’icyuma gisobekeranye cya pulasitike ikomatanya yujuje ibyangombwa bisabwa na GB9687 "Igipimo cy’isuku ku bicuruzwa byahinduwe na Polyethylene ku bicuruzwa bipfunyika ibiryo" na GV / Т17219 "Isuzuma ry’umutekano ku bikoresho byo gukwirakwiza amazi no ku bikoresho ndetse n’ibikoresho birinda". Nibisimburwa byiza kumuyoboro wa galvanis hamwe numuyoboro wibyuma.

Korohereza urukuta rw'imbere no kuzenguruka
Urukuta rw'imbere rw'umukandara wa mesh umukandara wa pulasitike uringaniye uroroshye, kandi ubukana bwuzuye ni 1/20 gusa cyumuyoboro wibyuma. Ubushobozi bwo gutanga ibintu mubihe bimwe burenga 30% kurenza ubw'icyuma.

Icyitonderwa: Umuvuduko wizina wumuyoboro uhuriweho ni umuvuduko ntarengwa wemerewe ko umuyoboro utwara amazi kuri 20 ° С. Niba ubushyuhe buhindutse, umuvuduko wakazi ugomba gukosorwa ukurikije coeffisente yubushyuhe bwibikoresho bitandukanye.

S agaciro: intera kuva diametre yinyuma yimbaraga kugirango igere hejuru yinyuma.
