Qhov txawv ntawm Brass Fittings PPR Fittings

Brass yeeb nkab fittings yog ib qho alloy uas muaj tooj liab thiab zinc nrog lub zog siab, zoo heev plasticity thiab corrosion kuj. Brass yeeb nkab fittings feem ntau yog siv rau hauv dej thiab HVAC systems ntawm high-end cov tsev, thiab lawv cov yam ntxwv tseem ceeb yog: kev khiav hauj lwm kub, siab compressive zog, zoo anti-corrosion muaj peev xwm, thiab ua tau yooj yim. Tus nqi ntawm tooj dag fittings yuav siab me ntsis dua li ntawm PPR yeeb nkab fittings.

PPR yeeb nkab fittings yog ua los ntawm random polypropylene raws li cov khoom siv tseem ceeb, thiab cov kav dej yog tsim los ntawm cov txheej txheem tshwj xeeb. Nws muaj cov khoom zoo ntawm lub cev thiab tshuaj lom neeg, kev cuam tshuam tsis kam, kub tsis kam, thiab sealing kev ua tau zoo. Nws yog tsim rau cov kav dej kub thiab dej txias thiab tshuaj lom neeg. kev xa khoom. PPR yeeb nkab fittings feem ntau yog siv rau hauv cov chaw nyob, cov chaw pej xeem thiab lwm qhov chaw. Nws cov yam ntxwv tseem ceeb yog: me me thermal conductivity, lub teeb yeeb nkab lub cev, tsis yooj yim rau hnub nyoog, thiab kev ua haujlwm siab. Ntxiv mus, PP-R yeeb nkab tsis muaj cov ntsiab lus halogen thiab yuav tsis tso cov tshuaj lom, yog li ua kom muaj kev nyab xeeb ntawm cov dej zoo.
