Obunene bw'okukozesa n'amakolero ga bimetal composite wear-payipu eziyiza .
Ebintu ebigumira okukulukuta nga ekyuma ekitali kizimbulukuse, inloy625 ne incoloy825 bitera okukozesebwa nga payipu za layeri ez’omunda okukakasa okugumira okukulukuta kwa payipu. Naye, ebintu eby’ebweru ebitera okuba x42, x50, x60, x70, ASTM-A106GB, A335-p22 n’ebintu ebirala okukakasa amaanyi ga payipu. Payipu y’ekyuma ekigatta erimu ebika by’ebintu bino ebibiri nayo esaanira okukola payipu eziyingira mu mazzi agava mu ttaka. Mu nsonga z’okukola amasannyalaze ag’ebbugumu, Japan, Amerika, Bulaaya n’amawanga amalala gakulaakulanya ultra-ebbugumu eringi ne ultra-ebyuma ebikuba puleesa ebya puleesa enkulu. Sumitomo Metal Company ekozesa SUS310S, 35 Cr-55ni, 40 cr-55Ni ebintu nga eby’ebweru layer base tube, 17-14 Cumo ne Alloy800h ebintu nga inner layer tube, era ekola enkola empya composite tube for supersuppercritical boiler superheat superheat superheatlical methodical. Sweden Sandvik efunye obuwanguzi mu kukola ekyuma kya kaboni ng’oluwuzi olw’omunda, ekyuma kya Sanicro28 nga kiziyiza bulungi okukulukuta nga layeri ey’ebweru, era ne kikola payipu y’ekyuma ekigatta okuyita mu kugatta ebyuma. Nga payipu y’okuziyiza okukulukuta kw’eddagala, ng’oggyeeko erina okuba n’obuziyiza obw’enjawulo obw’okukulukuta obw’omu makkati, nayo erina okuba n’amaanyi amangi n’okukaluba, kale ekika kino eky’ekyuma ekigatta n’ekintu ekisookerwako kitera okuba ekyuma kya kaboni, ekyuma ekiziyiza okukulukuta okutono oba okukulukuta, era layeri okusinziira ku kyuma eky’enjawulo ekiziyiza okukulukuta kiyinza okulonda ekyuma ekitaliimu buwuka, ekikomo n’ekikomo kyakyo ekinene ne niobium, tantalum ne titanum, etc. The composite steel pipe as incinerator superheater pipe is ideal, the outer base pipe can be selected with incineration high temperature resistance and corrosion resistance atmosphere materials (such as Sanicro65 alloy), the inner layer can choose carbon steel or chromium and molybdenum steel with stress corrosion resistance crack, Europe, the United States and other widely used since 1971. Sweden Sandvik choose high alloy nickel chromium steel UNSN08800 as inner pipe, with low alloy steel or ordinary boiler ASTMA213Ti2 for outer tube production heat exchanger composite steel pipe, has good thermal conductivity and excellent internal and external corrosion resistance, and maintain the low alloy steel good processing performance, desalination device of water intake pipe or seawater heat exchanger pipe can choose seawater corrosion resistant materials such as nickel, titanium, stainless steel or copper alloy lining, nga erina ekyuma kya kaboni oba ekyuma ekiziyiza okukulukuta okutono eky’ebweru ekiziyiza okukulukuta kw’ekyuma. Payipu y’ekyuma ekiziyiza okwambala ekozesebwa mu mbeera ey’okwambala ennyo nga butto w’amanda ag’amasannyalaze, butto w’ekirombe n’ebikuta ebitambuza amazzi, ebiyinza okukolebwa mu kyuma ekiziyiza okukulukuta kwa SUS316L n’ekisenge ekiziyiza okwambala ng’oluwuzi olw’omunda.
