Spiral welded pipefriction adhesion theory ikozvino yave kugamuchirwa zvakanyanya, mu static friction, iyo chaiyo yekubata nzvimbo inoenderana nemutoro.Uye kana kutsvedza kunotsvedza, isu tinofanirwa kufunga nezve kuvepo kwesimba rekugera, saka, kuwedzera spiral simbi chaiyo yekubata nzvimbo inobuda kubva kune yakajairika mutoro uye shear mutoro kune yakasanganiswa mhedzisiro ye.Izvo zvakare zvinogona kutaurwa kuti iyo goho poindi yekusangana inoitika, nekudzvinyirira kushushikana kunokonzerwa neyakajairwa mutoro uye tangential mutoro weiyo synthetic stress inokonzerwa neshear stress inoenderana.

Kana spiral welded pombi iri kukweshana mumhepo, pane kusvibiswa kwechisikigo nekuda kwemembrane yepamusoro, zviri muropa kushandisa friction phenomenon yakasvibiswa firimu adhesion theories iripo kutsanangura pamusoro pesimbi.Muchokwadi, yakawanda yesimbi yepasi inogara yakafukidzwa neyakaonda oxide firimu, uye nekudaro uku kukakavara kune simbi friction, kukweshera kweiyo oxide firimu kunonyanya kuve iyo oxide firimu, mushure mekuparadzwa kweiyo oxide firimu inongogoneka kuumba zvakananga kukwesha kwesimbi-kune-simbi.Kana yakaderera friction pamusoro yakasvibiswa, uye kusvibiswa kwe membrane shear simba, adhesion junction kukura haisi pachena.Apo iyo spiral simbi pombi apo membrane fouling shear stress inosvika pakuveura simba rekusvibisa membrane pamusoro pefirimu rakachekwa, kukwenya kwakatanga kutsvedza.Muchiitiko ichi, adhesive friction coefficient inogona kuratidzwa se f = k / v apo, nokuda kwekugera simba rekusvibiswa kwepamusoro firimu ndiyo goho remuviri wesimbi.
