NOV, headquartered in San Antonio, Texas, NOV, is a world-leading manufacturer of fiberglass reinforced epoxy pipe products. These pipeline products are available in low pressure and high pressure, mainly used to control and prevent corrosion in land and marine engineering. NOV's subsidiary Co., Ltd. has more than 60 years of experience in the oil and gas field field. The company's patented advanced composite thread (ACT) is recognized as the best high-pressure fiberglass pipeline joint system in the industry. In addition, downhole oil pipes using such joint systems also have excellent up/shackle performance. The low-pressure products produced by the company are also widely used in oil fields around the world, such as Star® Super Seal, Red Spiral® Type II pipelines and fittings.

The diameter range of pipeline pipes produced by the company is 1 ½″ ~ 36″ (40 ~ 900 mm); the pressure range is 150 psi (1.03 MPa) ~ 4000 psi (27.6 MPa); the maximum operation The temperature is 210°F (99°C). These pipelines are mainly used to transport highly corrosive substances from the central oil station of the oil field to the injection well. In addition, the pipeline tube is also used for the transport of medium/low pressure oil and gas containing corrosive fluids. Epoxy resin systems have chemical corrosion resistance and high temperature resistance, and glass fiber reinforced materials have a load-bearing capacity of large loads. NOV's Ray-Kiss FRP pipelines have achieved an expected service life of 20 years under 150°F (65.6°C) according to ASTM D-2992 Method B, with annular stress level (LCL) of 23,270 psi (160.5 MPa ) designed.

As a manufacturer of underground fiberglass products, NOV's subsidiary Co., Ltd. is a dominant position in the same industry due to its unique fiber zero-degree angle laying process that gives the products excellent tensile resistance. The diameter range of oil pipes provided by the company is 1 ½″ ~ 9 ⅝ ″ (40 mm ~ 250 mm), and the working pressure is 1000 ~ 3500 psi (7 MPa ~ 24 MPa). The diameter range of the sleeve products is 1 ½″~ 9 ⅝″ (40 mm ~ 250 mm), and the working pressure is 1000 ~ 3250 psi (7 MPa ~ 22.4 MPa).

The epoxy downhole oil pipes and casing products provided by the company use three curing agents with different properties, and the maximum temperature can be withstanded up to 200°F (93.3°C). The standard nominal length for all pipe products is 30 feet (9.1m). The downhole products produced by the company are suitable for various highly corrosive downhole environments, such as salt water injection wells with corrosive injection layers; monitoring wells that may interfere with monitoring equipment during production layers, as well as oil production wells where steel products are easily corroded. .

NOV’s subsidiary Co., Ltd. uses a 10-buckle per inch, 8-buckle per inch thickened long threads and OD 8-buckle thread joint system that complies with industry standard API 5B, which can be directly connected to steel threads. The connector system has threaded coupling joints (T&C) and integral joints (IJ). Compared with steel products, the joint system is a key consideration when determining the relevant performance of fiberglass (glass fiber reinforced epoxy). Because the joint system has an impact on the number of up/shackles of the column and lifting, installation speed, and matching with other products. The Raokis has a plan to continuously improve the joint system, such as the patented advanced composite thread (ACT), which contains graphite and ceramic powder, which enhances the upper/shackle performance of fiberglass pipes. The Raokiss An achievement in the joint system improvement planning.
