1. Ukuvulwa kwecala

Ukuvulwa kwecala kubhekisa kwinto yokuba i-pipeline ayikho kwi-perpendirsur okanye i-gepric kunye neflethi, kwaye umphezulu weflethi ayifani. Xa uxinzelelo oluphakathi lwangaphakathi ludlula uxinzelelo lwerhasi, ukuvuza iFlanger kuya kwenzeka. Le meko ibangelwa ikakhulu ngexesha lokufakwa, ukwakhiwa, okanye ulondolozo, kwaye ifunyenwe lula. Ngalo lonke ixesha lokuhlolwa kwenyani kwenziwa ngexesha lokugqitywa kweprojekthi, ezo zengozi ezinjalo zinokuthintelwa.

I-2. I-Stagger

I-Stagger ibhekisa kwimeko apho umbhobho kunye neflanges zigqitha, kodwa ezona zimbini zingahambelani. I-flange ayingxisini, ibangela ukuba iibhotile ezingqongileyo zingangeni ngokukhululekileyo imingxunya ye-bolt. Ngaphandle kokungabikho kwezinye iindlela, ukhetho kuphela kukwandisa umngxunya okanye faka i-bolt encinci kwi-bolt hole, eya kunciphisa uxinzelelo phakathi kwezi mpazamo zimbini. Ngapha koko, kukho ukuphambuka kumgca wokutywina komhlaba wokutywina, onokukhokelela ngokulula ekuvusweni.

3. Ukuvula

Ukuvulwa kubonisa ukuba ukucaciswa kweflethi enkulu kakhulu. Xa umsantsa phakathi kweflethi mkhulu kakhulu kwaye unobangela imithwalo yangaphandle, enjenge-axial okanye i-gasket iyachaphazeleka okanye ilahlekelwe ngamandla okutyhubela kwaye ilahlekelwa kukungaphumeleli.

4. Impazamo

Umngxunya ongalunganga ubhekisa ekuphambukayo phakathi kwemingxunya ye-bolt yombhobho kunye ne-flange, engxinaniso, kodwa umgama ophathwayo phakathi kweflethi ezimbini zinkulu. Ukusetyenziswa gwenxa kwemingxunya kunokubangela uxinzelelo kwiibhotile, kwaye ukuba la mandla akaphelelwa, kuya kubangela i-shear kwiibhotile. Ixesha elingaphezulu, kuya kucheba iibhotile kwaye zibangele ukungaphumeleli.

5. Impembelelo yoxinzelelo

Xa ufaka iflethi, unxibelelwano phakathi kweeflethi ezimbini zimiselwe ngokusemgangathweni. Nangona kunjalo, kwimveliso yeNkqubo, xa i-Pipeling ingena phakathi, ibangela ukuba i-pipeling iguqukele kumbhobho, ekhokelela ekukhuleni okanye i-pipeling yomthwalo, enokubangela ukugoba umthwalo okanye i-Shear kwi-Sheet kwaye ikhokelela ngokulula ukusilela kwegesi.

I-6. Iziphumo ze-corrosion

Ngenxa yokukhukuliseka kwexesha elide kwe-gasket ngokweendaba zezahlulo, i-gasket ye-gasket isebenza kwiinguqu zemichiza. Imithombo yeendaba ifuna kwi-gasket, ibangele ukuba iphazamise kwaye iphulukane namandla okuqhwaba, okukhokelela ekuvusweni kweflenge.

I-7. Ukwanda kwe-shirmal kunye nokuchasana

Ngenxa yokwandiswa kwe-shirm kunye nokwahlulahlula i-fluid ephakathi, i-bolts isanda okanye ikhontrakthi, kukhokelela kwizithuba ze-gasket kunye nokuvuza kwe-galtit.
