FAQ

I-Q1: Yintoni umbhobho we-spiral seam?

I-Spiral Seam Seam yenziwa kusetyenziswa indlela ekhethekileyo ebizwa ngokuba yinkqubo yokuphucula i-spilling. Le teknoloji ye-munction ibandakanya iikhoyili zentsimbi ezivuthiweyo ezivuthiweyo ezenziwa kwimo ye-cylindrical kwaye idlwengule ecaleni komthungo weSpily. The resulting pipe not only has high strength but also excellent durability, making it ideal for a variety of applications, including oil and gas transportation, water supply and structural support.

I-Q2: Kutheni ukhetha umgangatho weSpiral Seam Seam Seam?

Eyona nto iphambili kwimibhobho esemgangathweni ye-SPIP ephezulu kukwakha amandla. Inkqubo yokuphucula i-welding ivumela i-welding eqhubekayo, ephucula ingqibelelo kunye noxinzelelo lombhobho. Ukongeza, le mibhobho inokwenziwa kubungakanani obuhlukeneyo kunye nobugqwetha ukufezekisa iimfuno ezithile zeeprojekthi ezahlukeneyo.

Q3: Yintoni endifanele ndiyijonge kumthengisi?

Xa ukhetha umboneleli wetywina we-sping seam, kubalulekile ukukhetha inkampani ebeka ulwaneliseko lwabathengi kuqala. Jonga umthengisi onika intengiso yangaphambi kwentengiso, intengiso, kunye neenkonzo zasemva kwentengiso. Inkampani edumeyo iya kuqinisekisa ukuba iimveliso zayo ziyahlangabezana neenkcazo ezisekwe kwaye zinokwamkela iimfuno zakho ezizodwa, ziqinisekisa ukuba ufumana iimveliso ezikumgangatho ophezulu kunye neenkonzo eziza kuxabisa abathengi bakho.
