Hanwei Energy Services Corp - downhole pipe casing

By: Hanwei Energy  09-12-2011

Hanwei tubing and casing are made of E glass fiber and amine curing epoxy resin with the pipe body formed with a dual angle winding structure. The FRP pipes are generally produced without an inner liner layer but will be customized and engineered specifically according to users' request and application.

Maximum working pressure is 21MPa and is available in two temperature classes:

  1. Hanwei Acid Anhydride-cured System for Extended Operating Temperatures of 65°C
  2. Hanwei Aromatic Amine-cured System for Extended Operating Temperatures of 93°C

Pipe length is approximately 8.8 meters. Hanwei downhole tubing and casing are light weight and corrosion-resistant, fast and easy installation, non-conductive, low friction coefficient, and not prone to scaling and wax formation. Hanwei utilizes external upset oil pipe thread of 8-round (2 1/2" to 9 5/8") or 10-round (1.9") per inch as per the American Petroleum Institute (API) standards. They are generally connected with external thread and coupling with some integrally connected. All connecting threads are manufactured as per Table 2.2 and 2.6A of American Petroleum Institute standard 5B. We offer extension tube fittings matching various pipe diameters with length of 0.6m, 1.2m, 1.8m, 2.4m, and 3.0m. We can also offer extension tube fittings with special outer diameters upon users' requests.
