Insimbi engagqwali abakhiqizi bamapayipi ashiselwe bakukhumbuza ukuthi ukhethe umucu wensimbi engagqwali noma ipuleti lensimbi engagqwali elisetshenziselwa ukucubungula ipayipi elishiselwe insimbi engagqwali. Into yokuqala okufanele icatshangelwe ubukhulu bepayipi elishiselwe. Yiziphi izici ezicatshangelwayo ekucutshungulweni kwepayipi elishiselwe insimbi engagqwali? Kufanele sisebenzise ukujiya okuphusile nokulungile ukuze siqinisekise futhi sihlangabezane nezimfuneko zenkontileka ye-oda ukuze sinikeze abasebenzisi isiqinisekiso esiyisisekelo sokusebenzisa ngokuphephile.

Ugqinsi lomucu wensimbi engagqwali okhethiwe, ipuleti lensimbi engagqwali nepuleti kunqunywa ukujiya okuncane okuvumeleke nokubekezelela kwepayipi lensimbi, kodwa umkhiqizi wepayipi elishiselwe lensimbi engenasici i-Wenzhou uncoma ukuthi izici ezithinta ukujiya kodonga lwepayipi elishiselwe phakathi nokucubungula futhi ukukhiqizwa, njengokwenza, ukushisela, ukugaya i-Welding seam, ukwelashwa kokushisa, ukuqoqa, njll., lezi zingenza ukushuba kodonga lwepayipi elihlanganisiwe libe mncane.

Ngakho-ke, izici ezilandelayo kufanele zicatshangelwe ekunqumeni ubukhulu bezinto ezisetshenziselwa ukucubungula amapayipi ashiselwe ensimbi engagqwali:

1. Izindinganiso ezamukelwayo zokukhiqiza amapayipi ashiselwe;

2. Ukucaciswa kwepayipi lensimbi engagqwali elishiselwe (usayizi ojwayelekile: ububanzi x ukujiya kodonga);

3. Ukubekezelela ukushuba kodonga lwamapayipi ashiselwe;

4. Izinga lokubekezelela ukushuba kwensimbi;

5. Isibonelelo sokushisela seam;

6. Izici zokuphepha.

Ubukhulu bepuleti lensimbi engagqwali (ibhande lensimbi) elitholakala kulezi zici ezingenhla yilaba:

T = tk% t8 + 0.04 + 0.05

Lapho t kuwubukhulu obujwayelekile (obujwayelekile) bepayipi elishiselwe insimbi engagqwali;

k% ukubekezelela ukujiya kodonga (inani lika-k liyi-10%);

8.Kuwukubekezelelana kokuqina kwebhodi (ibhendi);

Lapho ukhetha izinto zokusetshenziswa lapho ucubungula amapayipi ensimbi engagqwali ashiselwe, thintana nomkhiqizi wamapayipi ashiselwe insimbi engagqwali ukuze ugweme ukulahlekelwa okungadingekile.
