Imicu ephikisayo efafaza uphahla lwesithando somlilo iwumkhiqizo omkhulu owenziwe nge-refractory fiber egayiwe. Ukuhlelwa kwefayibha kulo liner konke kuntengantenga, kunamandla athile okuqina ohlangothini olunqamulayo, futhi ohlangothini lwe-longitudinal (kubheke phansi okuqondile) amandla aqinile acishe abe ziro. Ngakho ngemva kwesikhathi esithile sokukhiqiza, amandla okwehla akhiqizwa isisindo se-fiber ngokwawo abangela ukuba umcu uxebuke.
Ukuze uxazulule le nkinga, inqubo yokudinga inqubo ebaluleke kakhulu ngemva kokufafaza uphahla lwesithando somlilo. Inqubo yokudinga isebenzisa "umshini wokuthungatha isithando somlilo wokufafaza" ukuze uguqule ungqimba lwefayibha efuthiwe ukusuka ekunqamuleni okuguquguqukayo okunezinhlangothi ezimbili kube ukunqamula kwegridi ye-longitudinal enezinhlangothi ezintathu. Ngakho-ke, amandla aqinile efayibha aba ngcono, okufana nomkhiqizo wemicu ephikisayo owakhiwe ngendlela emanzi uphansi kakhulu kumandla engubo yokulala edingekile yemicu ephikisayo eyakhiwe ngendlela eyomile.
Ukugcina uphawu nokushisa kwepayipi ngophahla lwesithando somlilo. Ishubhu yokuguqula yesithando sokushisa esishubhu idinga ukumelana nezinga elithile lokushisa eliphezulu esithandweni, futhi idinga futhi ukusebenza ngaphansi kwezinga lokushisa elishintsha njalo. Lo mehluko wezinga lokushisa ubangela isenzakalo sokunwetshwa nokufinyela ku-longitudinal kanye nezikhombisi-ndlela eziguquguqukayo zeshubhu lokuguqula. Ngemva kwesikhathi esithile, lesi senzakalo sokunwetshwa nokufinyela kudala igebe phakathi kwemicu ye-refractory nezinye izinto eziphikisayo ezizungeze ishubhu lokuguqula. Igebe libizwa nangokuthi i- through-type straight seam.
Ushicilelo olulandelayo sizoqhubeka nokwethula uhlelo lokusebenzaimicu ye-refractoryphezulu kwesithando somlilo se-tubular.
