Cov theem pib thiab cov cwj pwm tseem ceeb ntawm Kev Sib Txuas Cov Yeeb Nkab Cov Yeeb Nkab yog li nram qab no:

1. Daim ntawv thov lub npe:

Ip Grip Yeeb Nkab Taug Kev Siv Tau tuaj yeem thov rau qhov sib txuas qhov txuas ntawm 26.9mm-2032mm sab nraud lub raj xa hluav taws xob. Raws li cov chaw tsim khoom qhia txog, cov khoom lag luam nkoj nrog lub cheeb ntawm DN250 thiab hauv qab yog siv dav

Pressure Lub siab tsis kam ntawm Grip yeeb nkab txuas yog 3.2Mpa, kev ua haujlwm kub ntau yog li - 70 ℃ ~ + 300 ℃, thiab qhov ua hauj lwm siab tshaj plaws tuaj yeem tiv taus 6.7mpa. Tam sim no, nws yog feem ntau siv rau chav kawm 2 thiab 3 qhov raj dej ntawm lub nkoj.

Los ntawm kev siv cov roj hmab sib txawv lub nplhaib sib txawv, Cov yeeb nkab txuas txuas tuaj yeem siv rau dej hiav txwv, huab cua, chav, roj av, roj thiab lwm yam tshaj tawm. Cov roj hmab foob nplhaib muaj cov yam ntxwv ntawm tshav kub ua hauj, tshuaj tiv thaiv corrosion, thiab tiv tshav ntuj kub.

Cov yam ntxwv tseem ceeb

Qhov yooj yim prefabrication ntawm cov piping system: tsis xav tau cov tshuab flange los yog qhov khoob ntawm qhov kawg ntawm cov kav dej, txuag lub sijhawm prefabrication ntawm cov raj xa system.

Kev ua haujlwm dav dav: haum rau txhua hom hlau lossis kav hlau tsis muaj hlau, tsis muaj qhov tshwj xeeb xav tau rau nruab nrab, phab ntsa tuab thiab lub ntsej muag kawg ntawm cov yeeb nkab, haum rau ntau tshaj 80% ntawm cov raj xa dej ntawm lub nkoj.

Qhov nyhav ntawm cov yeeb nkab ntawm lub cev tuaj yeem txo kom txog 70% piv nrog tias ntawm qhov flange.

Txuag qhov chaw teeb tsa ntawm lub raj xa dej: tsis muaj flange kev tsim kho yog qhov yuav tsum tau ua rau kev tsis tuaj yeem thiab sib dhos, tsuas yog kho kom ruaj khov ntawm ib sab, yog li 50% ntawm cov raj xa dej thiab qhov chaw tsim kho tuaj yeem txuag。
