Upsetting
Tejas Tubular de Mexico forges tubing and drill pipe upset in accordance with API specifications and many other standards. Special upsets for premium and integral connection can also be forged upon request.
Heat Treating
We perform three types of heat treatment: quench and temper (Q&T), normalizing (Norm), and normalized and tempered (N&T). Tejas Tubular de Mexico uses gas fired furnaces and electrical induction furnaces for heat treatment of products. We have multiple heat-treatment lines to support various product needs and deliver diverse and large orders on time.

Inertia Welding
Weld integrity is a must in the oil field drilling industry. Proven reliability of inertia welded connections, coupled with the process advantages such as being clean, fast, consistent, and free of operator-induced error, makes inertia welding the only way to manufacture oilfield drill pipe.
Hot Sizing
To insure the diameters of the heat treated pipe are within the tolerances of API Specification 5CT all our casing is hot sized at temperatures higher than 850°F [454°C]. Our hot sizing operation, after tempering, substantially reduces ovality of the casing and enhances the collapse pressure rating.

Straightening
At Tejas Tubular de Mexico, all tubular products are visually inspected after heat treatment for deviation from straight or chord height to comply with API specifications and straightened with processors and cross roll straightened as required.
Hydro Testing
Tejas Tubular de Mexico has designed custom built plain end hydro testers which can apply test pressure to 15,000 psi [103,421 kPa]. Blank tubing is fed into the equipment where appropriate test pressure is applied and held for a specified time according to API specifications and customer requirements.
End Finishing
Each product is drift tested according to API specifications. High density polyethylene or plastic with metal insert thread protectors are installed wrench tight to avoid loosening during transport.
Sawing
We use high-speed production band saws in which tubes are cut to precise length, in order to be manufactured as couplings, pup joints or tool joints in different lengths and configurations.
CNC Machining
We use CNC lathes for the threading and/or machining of tubular products. CNC lathes allow us to produce precision finished products by using special programming and high-quality carbide tooling.
Inspection
All machined/threaded products are inspected and verified to be finished to the utmost accuracy and compliance to requirements
