1. Khatello ea phaephe ea PE ke efe?

Ho ya ka ditlhoko tsa maemo a naha tsa GB/T13663-2000, kgatello yaLiphaephe tsa PEe ka aroloa ka maemo a tšeletseng: 0.4MPa, 0.6MPa, 0.8MPa, 1.0MPa, 1.25MPa, le 1.6MPa. Joale data ena e bolela'ng? E bonolo haholo: Mohlala, 1.0 MPa, e bolelang hore khatello e tloaelehileng ea mosebetsi oa mofuta ona oaLisebelisoa tsa Hdpeke 1.0 MPa, e leng seo re atisang ho se bitsa kgatello ya 10 kg. Ehlile, tekong e fetileng ya kgatello, ho ya ka ditlhoko tsa maemo a naha, e hloka kgatello ka makgetlo a 1.5. Boloka kgatello ka dihora tse 24, ke hore, teko e etswa ka kgatello ya metsi ya 15 kg.

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

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

Ea boraro, potso ea bophara ba phaephe ea PE

Ka kakaretso, liphaephe tsa PE li na le bophara ba 20mm-1200mm. Bophara boo re buang ka bona mona bo bolela bophara ba kantle. Mohlala, phaephe ea PE ea De200 1.0MPa ha e le hantle ke PE e nang le bophara ba kantle ba 200, khatello ea 10 kg, le botenya ba lebota ba phaephe ea 11.9 mm.

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

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

Re tla ngola mekhoa e meng ea ho bala boima ba mithara ea liphaephe tsa PE. Metsoalle e hlokang e tla li hopola. E tla ba molemo bakeng sa mosebetsi oa nakong e tlang:

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

Hantle, ke phetho bakeng sa dikahare tsa kajeno. Bakeng sa tsebo e batsi ka diphaephe tsa PE, ka kopo tswela pele ho re ela hloko. Ikopanye le Shentong ho hapa mmaraka, re a amohela ho botsa.
