15,000
barrels
Storage tank
A 15,000-barrel tank fabricated and welded on site, with nondestructive testing on every joint.

- Fabricate
We cut, fit and weld structural steel, tanks and piping in our own shop. We qualify the procedure before the arc is struck: once the joint is in place, fixing it is paid for in downtime.
Explore fabrication - Weld
WPS, PQR and WPQ to ASME IX and AWS D1.1: the paperwork your inspector will ask for. We qualify the joint on coupons and the welder running it, for that position and thickness.
Explore welding - Erect
We rig and erect on site with our own crew. You get the structure plumb and torqued, plus the nondestructive testing file —UT, MT, PT, RT, VT— signed off by an ASNT-certified inspector.

Reach
How far
ONIX goes.
Anywhere in Venezuela
The job travels
We move the crew and the lifting equipment to your site anywhere in the country, and transport is part of the quote — it does not come back later as a separate line.
No geographic limit
The engineering does not travel
We deliver calculations, drawings and procedure qualification remotely, wherever your project is. This is the line ONIX serves outside Venezuela without moving a crew.
