# Oil, gas, and energy fabrication

Energy fabrication covers skids, pressure vessels, tanks, process piping, and structural supports for wells, plants, and pipelines.

## Materials and processes

Carbon steel pipe and plate, low-temperature and alloy steels, and stainless and duplex grades for corrosive service.

## Standards and certifications to know

- ASME Boiler and Pressure Vessel Code, Section VIII: governs pressure vessel design and fabrication; certified shops can apply the ASME certification mark.
- ASME B31.3: the process piping code.
- API standards: such as API 650 for welded storage tanks.
- NACE MR0175 / ISO 15156: materials requirements for sour (H2S) service.

## Questions to ask a shop

- Does the shop hold the ASME certification needed for this work (for example the U stamp for pressure vessels)?
- Which welding procedures are qualified for the material and code?
- How does it handle hydrotesting, radiography, and other NDE?
- Can it document material traceability for every heat number?

## What drives cost

Code requirements, testing and NDE, alloy material, and documentation can outweigh welding labor. Remote site work adds travel and logistics.
