Lined pipekubva mumucheka wemukati ndeye kupfeka, iyo insulating layer, simbi yemadziro.Parizvino yakamisikidzwa pombi network kushandisa mamwe mabhomba ane mitsetse yakapetwa kaviri, hapana mabhomba simbi uye faibha-yakasimbiswa kaviri lining, hapana imwechete hexagonal mesh yesimbi fiber yakasimbiswa lining uye mamwe mafomu.Nekuti mushure mekushandisa lining yekushushikana kwepombi, kuomarara kwakave nekukanganisa kukuru.
Dzvinyiriro kubva papombi, uremu hoop kushushikana uye mutoro wekunze wakagadzira axial kushushikana (pamwe chete zvakanaka kushushikana) uye shear stress yekunze simba uye nguva yakaenzana mamiriro anofanirwa kusangana.Kunyanya kunetseka deformation inogadzirwa nekuwedzera kusingadzivirirwe (kureva, hapana kuzvidzora), zvichikonzera kukuvara.Iyi stress state ndeye membrane stress.Kupeta kushushikana kunokonzerwa nehuremu uye mutoro wekunze ipfungwa yekukotama.Kupeta kushushikana muchikamu chepombi ndiko kugovera mutsara wakatwasuka.A side cross-sectional tensile stress, compressive stress and the other side, the neutral axis through the center of the stress is zero.Apo rusvingo rwepombi rwakatanga kupinda mugoho, pedyo neakisi yakasara ichiri mune elastic state.Saka anogona kuramba kutakura mutoro, uye kushushikana redistribution.Kushushikana uku kunogona kushandiswa kuongorora pfungwa yekupedzisira mutoro, ichibvumira nzvimbo yepamusoro kupfuura yekupedzisira firimu inobvumirwa kushushikana kukosha.Kazhinji nekuda kwezvikonzero zvekuchengetedza, izvo zvinopihwa hazvigone kudarika kushushikana kwepombi kamwechete kunetseka kunobvumidzwa.Iko kukosha kwekunetseka kwepasi kana kuenzana neinobvumirwa kushanda tembiricha kushushikana, pombi inogona kushanda zvakachengeteka.
Nekuda kwehuremu hwehuremu hwepombi hunowedzera, zvinotungamira kune yakatsiga yekunze mutoro wekushushikana mapaipi ane akasiyana kwazvo pamberi uye mushure meiyo liner, saka, inoda kutariswa.Mukuenderera mberi kwemutoro wekunze kushushikana, kukotama kushushikana kurema kwakakonzera kukanganisa kukuru pakushushikana kwepombi.Mukugadzirwa kwemahombe-diameter tembiricha yepombi, kutonhora-madziro dhizaini ndiko kushandiswa kwemafuta ekuvharidzira lining zvinhu kugadzira pombi madziro tembiricha kure pasi pekushisa kwepakati.Pipe yekupisa kushushikana mazinga nekuda kwekudzikira kwekushisa kwakadzikira zvakanyanya mushure meiyo liner zvinoenderana nemasimba ezvivakwa zvekongiri lining zvinhu zvinoratidza kushomeka kwayo kusimba, kumanikidza simba rakakura.Kuwedzera kupisa kweiyo liner pombi kushushikana kwakagovaniswa pombi uye liner zvinhu mukupisa kwekuwedzera kushushikana kusimba kushushikana, kusimba kwesimba nekuda kwekushomeka kwezvinhu zvembambo, kupisa kushushikana kwesimbi machubhu kushoma.Kana iyo yekupisa yekuwedzera kushushikana kuri kumanikidza kushushikana, iyo yekumanikidza simba reiyo liner zvinhu zviri nani nekuda kweiyo compression kushushikana inonyanya kuumbwa neiyo lining zvinhu chiyero, kupisa kushushikana kwesimbi kwakanyanya kukanganisa.
