Tubooyinka leh Dahaarka ka hortagga daxalka

Heerarka: Heerarka tuubooyinka dahaarka leh ee ka-hortagga daxalka waxaa dejiya ururro ay ka mid yihiin Bulshada Maraykanka ee Tijaabada iyo Qalabka (ASTM), Ururka Caalamiga ah ee Halbeega (ISO) iyo Bulshada Qaranka ee Injineerada Daxalka (NACE). Heerarkani waxay qeexayaan shuruudaha alaabta daahan, hababka codsiga, hababka tijaabada iyo heerarka waxqabadka.

Kala soocida ku salaysan daaweynta dusha: Tuubooyinka leh dahaarka ka-hortagga daxalka ayaa loo kala saari karaa iyadoo lagu saleynayo nooca dahaarka loo isticmaalo. Qaybaha caadiga ah waxaa ka mid ah: Dahaarka Isku-dhafka ah ee Epoxy (FBE) Dahaarka Polyethylene (PE) ama polypropylene (PP) daahan Asphalt ama daahan Zinc oo qani ku ah rinjiga Polyurethane daahan Dhuxul daah dhaldhalaalka ah.

Codsiyada: Tubooyinka leh daahan ka-hortagga daxalka ayaa si weyn looga isticmaalaa warshadaha kala duwan, oo ay ku jiraan: Saliidda iyo Gaaska: Dhuumaha loo isticmaalo in lagu qaado saliid ceyriin, gaaska dabiiciga ah iyo batroolka Biyaha iyo biyaha wasakhda ah: biyaha dhulka iyo bulaacada Kiimikada iyo petrochemical: qaadista kiimikooyinka daxalka ah iyo asiidhka badda. iyo xeebaha badda: ee dhuumaha badda hoostiisa iyo dhismayaasha xeebaha Kaabayaasha: Si loogu isticmaalo on buundooyinka, doomaha iyo dhismayaasha kale ee soo bandhigay xaaladaha adag deegaanka Tuubooyinka Kuwani waa muhiim si ay u ilaaliyaan daacadnimada iyo cimri dherer ee kaabayaasha muhiimka ah iyo nidaamyada warshadaha, gaar ahaan meelaha adag ama daxalka. Marka la tilmaamayo ama la dooranayo tuubo leh dahaarka ka hortagga daxalka, waxaa muhiim ah in la tixraaco heerarka ku habboon oo lala tashado khabiirada warshadaha si loo hubiyo in dahaarka la doortay uu buuxiyo shuruudaha gaarka ah ee codsiga loogu talagalay.
