Processes
As one of the leading manufacturers of Oil Country Tubular Goods in the USA, we incorporate our core values into our manufacturing model consisting of upsetting, heat treatment, NDT, and threading operations. We are licensed and capable of producing grades J55, K55, L80, N80, C90, T95, C110, P110, Q125, E75, X95, G105, and S135. Our threading capabilities include EUE, NUE, USS IMP BTT, STC, LTC and BTC connections along with API rotary shouldered connections and all our semi-premium and premium connections.
Upsetting
We forge tubing and drill pipe upsets in accordance with API specifications and your requirements. Special upsets for premium and integral connections can also be forged upon request.
Heat Treating
We perform three types of heat treatment: quench & temper (Q&T), normalizing, and normalize & temper (N&T). We use 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 orders on time.
Hot Sizing
We are the only processor with hot sizing and hot straightening capabilities in the U.S. To ensure the OD 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 ratings.
Straightening
All our casing products undergo hot-straightening after temper. Tubing products are inspected for straightness after heat treatment to ensure compliance with our in-house and API requirements. Any questionable product is subjected to either cross-roll or pin straightening.
Hydro Testing
All our facilities have in-line hydrostatic testers to comply with API requirements. We also have a custom-built plain end hydro testers which can attain test pressures as high as 20,000 psi [103,421 kPa], to cater to your special testing requirements.
CNC Machining
Our high-speed automated CNC threading capabilities allow us to produce precision-finished couplings and pins; our in-house tolerance on thread elements of 8rd and buttress are half of API limits.
