9. This discussion is focussed on our business related to valve Industry
The promoters of Primo hail from the valve Industry and between them have 20 years of experience in Audco India Limited.
Primo has a rich experience since 1995 in the valve Industry having served over 40 customers with 75+ machines.
Primo’s machine making ability is synergically matched by it’s job working arm (Omplas systems) that melts a few tons of Stellites, Inconels, AISI 430 and other related grades every single year since 1993 for it’s various customers in the Valve manufacturing, Oil&Gas & Power sectors.

10. PROCESSES USED BY PRIMO
PTA – Plasma Transferred Arc process for depositing alloys in powder form.
Hot wire TIG for depositing Inconel 625 on the valves and components used in the Oil and Gas sector
GMAW – Gas metal arc welding for joining of seat rings to valve body & end flanges to valve bodies and bonnets to valve bodies.
SAW – Submerged arc welding for depositing 13% Chromium stainless steel over carbon steel.
