Dhuumaha birta isku dhafan ee galvanized ee sahayda biyaha iyo dab-damiska caag ah
Tuubooyinka biyaha dahaarka leh ee caagga ah, Loogu talagalay resin epoxy ama budada polyetylen ee la beddelay gudaha iyo dibadda tuubada caagga ah ee dahaarka leh.
Tuubooyinka biyaha dahaarka caag ah, Waxay leedahay wax qabad aad u fiican oo dhamaystiran iyo iska caabin daxalka xoog leh, isticmaalka heerkulka dibadda -40 ℃ - 90 ℃.Heerkulka gudbinta biyaha ee lagu dabaqi karo waa -30 ℃ - 80 ℃.Tuubada birta ah ee dahaarka leh ee loogu talagalay bixinta biyaha ayaa ka sareysa xasiloonida kiimikada iyo waxqabadka fayadhowrka, waxayna si buuxda u waafaqsan tahay heerka qiimeynta badbaadada ee gudbinta biyaha la cabbo iyo qaybinta qalabka iyo qalabka ilaalinta.
Tuubooyinka Biyaha ee Dahaarka leh ee Caaga ah, Tilmaamaha Alaabta
Biyaha sahayda dahaarka leh ee tuubada birta ah ee dahaarka ah ayaa siman, qurux badan, midabka iftiinka dibadeed wuxuu noqon karaa ikhtiyaar.Sababtoo ah darbiga gudaha ee siman, waxay ka hortagi kartaa taranta microorganisms, iska caabin yar oo gudbinta dareeraha, waxay kordhin kartaa socodka, badbaadinta tamarta, waxaa loo isticmaalaa dhammaan noocyada kala duwan ee sahayda biyaha iyo injineernimada dheecaanka.
Tuubooyinka Biyaha ee Dahaarka leh, Baaxadda Codsiga
Inta badan loo isticmaalo dhuumaha biyaha la cabbo, iyo biyaha badda, biyaha dib loo ceshaday, kiimikaad iyo batroolka, iyo inta badan aashitada, alkali, milixda, gaar ahaan ku habboon dhuumaha la aasay, nolosha adeegga 50 sano.
Tuubooyinka Biyaha ee Dahaarka leh, Tusmada Waxqabadka
1, xoogga dhamaystiran oo aan ka yarayn 1.6mpa;
2, imtixaanka foorarsiga ee u dhexeeya dahaarka ma dhicin, ifafaale jabka;
