Sisanda kusayina inkontileka nekhasimende laseNdiya ngesonto eledlule. Umkhiqizo uyipayipi lensimbi engenamthungoI-ASTM A335 P11. Sinohlu oluthile lwemikhiqizo ye-alloy, ukuze sitholele amakhasimende imikhiqizo. Ikhasimende leli payipi lisetshenziselwa ishubhu elicijile, ishubhu elicijile njengengxenye yokushintshanisa ukushisa, ukusebenza isikhathi eside esimweni segesi eshisayo yokushisa ephezulu, njenge-boiler heat exchanger eneshubhu elifakwe ipayipi esebenzisa indawo embi, izinga lokushisa eliphezulu nomfutho ophezulu kanye nokugqwala. Umkhathi, odinga i-tube ene-finned kufanele ibe nenkomba yokusebenza ephezulu. Okufana nokusebenza kwe-Anti-corrosion, ukusebenza kwe-Anti-wear, ukumelana nokuxhumana okuphansi, Ukuzinza Okuphakeme kanye nekhono lokulwa nokugqwala komlotha.

Siphinde sibe nakhoI-ASME A210(A210M) GrA1,GrC, ipayipi likabhayela kanye nepayipi le-boiler flue, okuhlanganisa i-vault yokugcina indawo yokuphepha kanye nepayipi le-strut kanye nogqinsi oluncanyana lwepayipi lensimbi elingenamthungo eliphakathi nendawo lepayipi le-superheater.

ASME A179, ASMEA192 njalo njalo.
