1. Khatello ea pipe ea PE ke efe?

Ho ea ka litlhoko tsa maemo a naha tsa GB/T13663-2000, khatello eaLiphaephe tsa PEe ka aroloa ka mekhahlelo e tšeletseng: 0.4MPa, 0.6MPa, 0.8MPa, 1.0MPa, 1.25MPa, le 1.6MPa. Joale data ee e bolela'ng? E bonolo haholo: Ka mohlala, 1.0 MPa, e bolelang hore khatello e tloaelehileng ea ho sebetsa ea mofuta ona oaLisebelisoa tsa HDpeke 1.0 MPa, e leng seo hangata re se bitsang khatello ea 10 kg. Ha e le hantle, tekong e fetileng ea khatello, ho ea ka litlhoko tsa litekanyetso tsa naha, ho hlokahala hore e be khatello ea makhetlo a 1,5. Boloka khatello ea lihora tse 24, ke hore, tlhahlobo e etsoa ka khatello ea metsi ea lik'hilograma tse 15.

2. Boleng ba SDR ba pipe ea PE ke bofe?

Boleng ba SDR, bo tsejoang hape e le karo-karolelano ea boholo bo tloaelehileng, ke karo-karolelano ea bophara ba kantle ho botenya ba lebota. Hangata re sebelisa boleng ba SDR ho emela tekanyo ea khatello ea kilogram. Maemo a tšoanang a SDR a mekhahlelo e tšeletseng ea 0.4MPa, 0.6MPa, 0.8MPa, 1.0MPa, 1.25MPa, le 1.6MPa ke: SDR33/SDR26/SDR21/SDR17/SDR13.6/SDR11.

Ntlha ea boraro, potso ea bophara ba pipe ea PE

Ka kakaretso, liphaephe tsa PE li na le bophara ba 20mm-1200mm. Bophara boo re buang ka bona mona bo hlile bo bua ka bophara bo ka ntle. Ka mohlala, pipe ea PE ea De200 1.0MPa ha e le hantle ke PE e nang le bophara bo ka ntle ba 200, khatello ea lik'hilograma tse 10, le botenya ba lerako la 11.9 mm. phaephe.

Ea bone, mokhoa oa ho bala boima ba mithara oa pipe ea PE

Ha basebelisi ba bangata ba tla ho botsa ka theko eaLisebelisoa tsa Pipe tsa Hdpe, ba bang ba tla botsa hore na kilogram ke bokae, re hloka ho sebelisa karolo e le 'ngoe ea data mona-boima ba mithara.

Re tla ngola liforomo tse ling tsa ho bala boima ba mithara ba liphaephe tsa PE. Metsoalle e hlokang e tla ba hopola. E tla thusa bakeng sa mosebetsi o tlang:

Boima ba mithara (kg/m)=(botenya ba bokantle ba bophara ba lebota)*botenya ba lebota*3.14*1.05/1000

Hantle, ke tsohle bakeng sa litaba tsa kajeno. Bakeng sa tsebo e eketsehileng ka liphaephe tsa PE, ka kopo tsoela pele ho re ela hloko. Kopana matsoho le Shentong ho hapa 'maraka, amohela ho botsa.
