Cov ntaub ntawv tseem ceeb ntawm API hoses feem ntau suav nrog cov hauv qab no:
1. Cov khoom siv roj hmab: Cov roj hmab yog cov khoom tseem ceeb ntawm API hoses, thiab cov roj hmab hluavtaws feem ntau yog siv, xws li nitrile roj hmab (NBR), acrylic roj hmab (ACM), chloroprene roj hmab (CR), thiab lwm yam. Cov khoom siv roj hmab no muaj roj zoo. , hnav tsis kam, kub tsis kam thiab corrosion kuj.
2. Reinforcement txheej txheej: txhawm rau txhim kho lub siab tsis kam ntawm API hoses, cov roj hmab sab hauv cov roj hmab feem ntau yog them nrog txheej txheej ntawm cov khoom siv ntxiv, feem ntau yog siv lub zog siab steel hlau braid lossis steel hlau kauv txheej. Cov ntaub ntawv txhawb nqa no tuaj yeem tiv taus siab thiab tiv thaiv kev khoov, ua rau lub hose tiv taus ntau dua rau siab thiab puas.
3. Insulating txheej cov ntaub ntawv: Cov txheej insulating feem ntau yog siv los tiv thaiv kev cuam tshuam ntawm sab nraud kub thiab ib puag ncig ntawm qhov nruab nrab ntawm lub hose. Feem ntau, cov ntaub ntawv xws li polyester lossis polyamide yog siv los ua txheej txheej insulating. Cov txheej txheej rwb thaiv tsev muab cov thermal rwb thaiv tsev zoo thiab tuav kom sov.
4. Cov khoom siv npog sab nrauv: txhawm rau tiv thaiv lub hose los ntawm kev puas tsuaj thiab xeb los ntawm ib puag ncig sab nraud, txheej txheej ntawm lub hose feem ntau yog them nrog txheej txheej txheej txheej. Cov ntaub npog sab nrauv tuaj yeem yog roj hmab, polyurethane, polyvinyl chloride (PVC), thiab lwm yam, uas muaj kev hnav tsis kam, huab cua tsis kam thiab corrosion kuj.
Cov khoom siv raw no muaj cov yam ntxwv hauv qab no:
1. Roj kuj: API hoses yuav tsum tau tiv taus cov roj thiab tshuaj nyob rau hauv cov kua thauj. Roj hmab thiab cov khoom siv ntxiv muaj cov roj zoo thiab tuaj yeem tiv taus qhov yaig thiab corrosion ntawm roj.
2. Hnav tsis kam: Lub hose yuav raug hnav thiab kev sib txhuam thaum ua haujlwm. Roj hmab thiab cov ntaub ntawv txhawb nqa muaj kev hnav zoo thiab tuaj yeem ua rau lub neej ua haujlwm ntawm lub hose.
3. Kev kub siab ua haujlwm: API hoses yuav tsum tiv taus qhov kub thiab txias raws li qee qhov kev ua haujlwm tshwj xeeb. Cov khoom siv roj hmab muaj qhov kub thiab txias tsis kam thiab tuaj yeem tswj lub zog thiab elasticity ntawm cov hoses.
4. Kev tiv thaiv corrosion: Nyob rau hauv qee qhov kev ua haujlwm tshwj xeeb, cov khoom siv roj hmab thiab cov ntaub npog yuav tsum muaj kev tiv thaiv corrosion zoo thiab muaj peev xwm tiv taus kev yaig ntawm cov tshuaj xws li acids thiab alkalis.
