1. Menene matsa lamba na PE bututu?

Bisa ga kasa misali bukatun GB/T13663-2000, matsa lamba naPE bututuana iya raba shi zuwa matakai shida: 0.4MPa, 0.6MPa, 0.8MPa, 1.0MPa, 1.25MPa, da 1.6MPa. To menene ma'anar wannan bayanan? Mai sauqi qwarai: Alal misali, 1.0 MPa, wanda ke nufin cewa al'ada aiki matsa lamba na irin wannanHdpe Fittingsshine 1.0 MPa, wanda shine abin da muke yawan kira 10 kg matsa lamba. Tabbas, a cikin gwajin matsa lamba na baya, bisa ga buƙatun ka'idodin ƙasa, yana buƙatar matsa lamba sau 1.5. Ci gaba da matsa lamba na tsawon sa'o'i 24, wato, ana yin gwajin tare da matsa lamba na 15 kg.

2. Menene darajar SDR na bututun PE?

Ƙimar SDR, wanda kuma aka sani da daidaitaccen girman rabo, rabo ne na diamita na waje zuwa kaurin bango. Yawancin lokaci muna amfani da ƙimar SDR don wakiltar ƙimar matsi na kilogram. Matsakaicin ƙimar SDR na matakan shida na 0.4MPa, 0.6MPa, 0.8MPa, 1.0MPa, 1.25MPa, da 1.6MPa sune: SDR33/SDR26/SDR21/SDR17/SDR13.6/SDR11.

Na uku, tambayar diamita na bututun PE

Gabaɗaya, bututun PE suna da diamita na 20mm-1200mm. Diamita da muke magana game da ita a zahiri tana nufin diamita na waje. Misali, bututun PE na De200 1.0MPa shine ainihin PE tare da diamita na waje na 200, matsa lamba na kilogiram 10, da kauri na bango na 11.9 mm. bututu.

Na hudu, hanyar lissafi na nauyin mita na bututun PE

Lokacin da masu amfani da yawa suka zo don tambaya game da farashinHdpe Pipe Fittings, wasu za su tambayi nawa ne kilogiram, muna buƙatar yin amfani da yanki ɗaya na bayanai a nan - nauyin mita.

Za mu rubuta wasu dabaru don ƙididdige nauyin mita na bututun PE. Abokan da suke bukata za su tuna da su. Zai taimaka don aikin gaba:

Nauyin Mita (kg/m)=(kaurin bangon diamita na waje)* kaurin bango*3.14*1.05/1000

To, wannan ke nan don abubuwan yau. Don ƙarin sani game da bututun PE, da fatan za a ci gaba da kula da mu. Haɗa hannu tare da Shentong don cin nasara kasuwa, maraba don tambaya.
