Bar, MPa, PSI da kg/cm ⊃2; Teburin Juya

Mahimman dabarun juyawa:

• MPa = Bar × 0.1

• Bar = MPa × 10

• PSI ≈ Bar × 14.5

• Bar ≈ PSI × 0.06895

• Bar ≈ kg/cm² × 0.9807 (kusa da ƙimar filin 1:1)

Misali: 16 mashaya = 1.6 MPa ≈ 232 PSI ≈ 16.3 kg/cm² - juzu'in da ya cancanci haddacewa, tunda kuma yana faruwa don bayyana ƙimar PN16.

Menene PN10 da PN16 suke nufi?

Ba kamar Bar, MPa da PSI ba, waɗanda raka'o'in matsa lamba ne, PN rabe-rabe ne na matsa lamba da ake amfani da shi don bututu, kayan aiki da bawuloli a ƙarƙashin ka'idodin tushen DIN/ISO.

Gajerun hanya mai amfani: lambar PN ita ce ƙimar mashaya. PN10 ≈ 10 mashaya, PN16 ≈ 16 mashaya. Amma ba darajar MPa ba - PN16 yana nufin 1.6 MPa, ba 16 MPa ba (16 MPa zai kasance kusa da mashaya 160, nau'in matsa lamba daban-daban gaba ɗaya).

PN ba shine kawai tsarin kima da za ku ci karo da shi ba. SCH (Jadawalin) ratings karkashin ASTM/ASME bayyana bango kauri maimakon matsa lamba kai tsaye, da kuma SDR (Standard Dimension Ratio) da ake amfani da PE / HDPE piping karkashin ISO 4427. Babu daya daga cikin uku ne kai tsaye interchangeable - a takaice cewa Mixes 'PN16' da 'SCH80 ' da 'SCH80 ' a kan wani gama-gari da lissafin kudi.

PN10 vs PN16: Wanne Ya Kamata Ku Zaba?

• Yanayin aiki

• Bututu da kayan dacewa

• Ana jigilar ruwa

• Juyin matsin lamba, guduma ruwa ko hawan jini

FAQ

Bar nawa ne 1 MPa? 1 MPa = 10 bar.

PSI nawa ne mashaya 16? 16 mashaya ≈ 232 PSI.

Shin PN10 daidai yake da mashaya 10? Kimanin - PN10 ≈ 10 mashaya ≈ 1.0 MPa ≈ 145 PSI a ma'aunin zafin jiki.

Shin PN16 yana nufin 16 MPa? A'a. PN16 yayi daidai da mashaya 16, wanda yayi daidai da 1.6 MPa - ba 16 MPa ba. 16 MPa zai zama kusan mashaya 160, aji mafi girma.

Za a iya amfani da PN16 PVC dacewa a 40 ° C? Ƙimar 16-bar yana aiki a 20 ° C. A 40°C, ana rage matsi mai ƙyalli na PVC, don haka bincika ginshiƙi mai ƙima - CPVC yawanci shine mafi kyawun zaɓi da zarar yanayin zafi ya wuce iyakar aikin PVC.
