Quality Tubular Assembly Services

Tubular Assembly

G & J Steel & Tubing, Inc. can build custom assemblies to customer requirements. In addition to fabricating the parts in our machine shop, we offer such assembly services as MiG welding, TiG welding, laser welding and brazing. Welding and brazing services are performed in-house. For services requiring furnace processing and laser welding we use highly qualified and certified sub-contract vendors.

Testing services are available for all assembled products including pressure/leak testing, mechanical, tensile, hardness and chemical property testing.

We can also install fastening hardware (tube fittings, flare nuts and sleeves) and custom mounting hardware (brackets and fittings) using many methods including riveting, mechanical locking, gluing or welding. Some example applications include burner assemblies and gas line assemblies.

G & J Steel & Tubing was the developer of a proprietary, patent-pending design for a pilot tube and pilot fitting assembly that was superior to the industry standard in terms of reliability and ease of insertion, and was less costly. The design is still widely used in the Gas & Appliance industry.
