Plastic End Caps puas siv tau rau cov kav hlau?

Yas yog ib yam khoom siv hnyav, nrog rau qhov sib txheeb ze ntawm 0.90 thiab 2.2. Feem ntau ntawm cov plastics pom zoo heev tiv thaiv corrosion los ntawm cov tshuaj xws li acids thiab alkalis. Lub hau steel yeeb nkab yog cov yeeb nkab haum- yog welded rau cov yeeb nkab kawg los yog haum rau cov xov sab nraud ntawm cov yeeb nkab kawg - siv los kaw cov yeeb nkab.

Nws ua haujlwm kaw lub raj xa dej, ua haujlwm zoo ib yam li cov yeeb nkab ntsaws. Raws li lawv cov ntaub ntawv muaj pes tsawg leeg, steel yeeb nkab caps tuaj yeem muab faib ua carbon steel caps, alloy steel caps, thiab stainless hlau caps.

Cov fittings no yog welded rau cov yeeb nkab kawg los yog mounted rau sab nraud threads los kaw cov yeeb nkab. Lawv siv los kaw cov kav dej, ua haujlwm tib lub hom phiaj raws li cov yeeb nkab ntsaws. Lawv daim ntawv zoo ib yam li qhov muag tsis pom flange; Txawm li cas los xij, lub qhov muag tsis pom flange yog ib lub foob uas tshem tau, hos lub welded yeeb nkab cap yog ib qho uas tsis yog - tshem tau.

Pipe caps encompass ntau yam tsim, nrog rau hemispherical caps, conical shells, txo seem, ca caps, thiab constricted kawg.

Lub kaus mom hlau yog suav tias yog kev tu cev, tsis yog - lom, thiab eco- cov khoom siv hauv tsev. Los ntawm kev ua cov txheej txheem ntawm cov yeeb nkab steel hau thiab fittings rau pickling thiab passivation kev kho mob -yog li ua kom cov thickness ntawm chromium- nplua nuj oxide txheej- corrosion kuj ntawm cov kaus mom hlau tuaj yeem txhim kho tau zoo.

Vim lawv cov yam ntxwv ua haujlwm zoo, cov yeeb nkab steel hau tau siv dav hauv ob qho tib si hauv tsev thiab chaw tsim khoom, thiab tshwj xeeb tshaj yog zoo - haum rau siv hauv cov kav dej ntshiab huv.

Hais txog cov khoom siv kho tshuab-xws li hardness, tensile zog, elongation, thiab cuam tshuam lub zog-plastics nthuav tawm ntau yam ntawm cov yam ntxwv, muab ntau yam kev xaiv xaiv los ntawm cov ntawv thov tshwj xeeb.
