Qalabka Qaybaha Ugu Muhiimsan:
| Qaybaha | Alaab |
| Jidh | CI,DI,WCB,ALB,CF8,CF8M |
| Saxanka | DI,WCB,ALB,CF8,CF8M,Cajalad caag ah oo la safeeyey,birta aan daxalka lahayn ee laba-jibbaaran,Monel |
| Jirrid | SS416, SS420, SS431, 17-4PH |
| Kursiga | NBR, EPDM, Viton, PTFE |
| Biin Taper ah | SS416, SS420, SS431, 17-4PH |
Qeexitaanka Kursiga:
| Alaab | Heerkulka | Adeegso Sharaxaadda |
| NBR | -23℃ ~ 82℃ | Buna-NBR: (Nitrile Butadiene Rubber) wuxuu leeyahay awood jilicsan oo wanaagsan iyo iska caabin xoqidda. Sidoo kale wuxuu u adkaystaa alaabada hydrocarbon-ka. Waa agab adeeg guud oo wanaagsan oo loogu isticmaalo biyaha, vacuum, aashitada, cusbada, alkaline-ka, dufanka, saliidaha, saliidaha, saliidaha hydraulic iyo ethylene glycol. Buna-N looma isticmaali karo acetone, ketones iyo hydrocarbons-ka nitrile-ka ama chlorine-ka leh. |
| Waqtiga toogashada-23℃ ~ 120℃ | ||
| EPDM | -20 ℃~130℃ | Caag EPDM oo guud: waa caag si fiican loo isticmaalo oo loo isticmaalo biyaha kulul, cabitaannada, nidaamyada wax soo saarka caanaha iyo kuwa ka kooban ketones, aalkolo, nitric ether esters iyo glycerol. Laakiin EPDM looma isticmaali karo saliidaha ku salaysan hydrocarbon, macdanaha ama dareerayaasha. |
| Waqtiga toogashada-30℃ ~ 150℃ | ||
| Viton | -10 ℃~ 180℃ | Viton waa elastomer hydrocarbon ah oo fluorinated ah oo leh iska caabin aad u fiican inta badan saliidaha hydrocarbon iyo gaasaska iyo alaabada kale ee ku salaysan batroolka. Viton looma isticmaali karo adeegga uumiga, biyaha kulul ee ka sarreeya 82℃ ama alkaline-ka xooggan. |
| PTFE | -5℃ ~ 110℃ | PTFE waxay leedahay xasilooni wanaagsan oo ku saabsan waxqabadka kiimikada dusha sarena ma dhegdhegayso. Isla mar ahaantaana, waxay leedahay sifo saliideed oo wanaagsan iyo iska caabin gabowga. Waa agab wanaagsan oo loogu isticmaalo asiidhyada, alkalis, oksaydheynta iyo kuwa kale ee sunta ah. |
| (Dahaarka gudaha ee EDPM) | ||
| PTFE | -5℃~90℃ | |
| (Dahaarka gudaha ee NBR) |
Hawlgalka:kabaalka, sanduuqa geerka, hawl-wadeenka korontada, hawl-wadeenka pneumatic.
Astaamaha:
1. Naqshadeynta madaxa stem ee Double "D" ama iskutallaabta laba jibbaaran: Ku habboon in lala xiriiro dhaqaajiyeyaal kala duwan, keena xoog badan;
2. Darawalka laba-geesoodka ah ee stem: Xidhiidhka aan booska lahayn wuxuu khuseeyaa xaalad kasta oo liidata;
3. Jidh aan lahayn qaab-dhismeed: Kursigu wuxuu si sax ah u kala saari karaa jirka iyo dareeraha, waana ku habboon yahay flange tuubo.
