API Oil Drilling Hose is divided into:High-pressure drilling and cementing hose,Rotating drilling equipment hoses,Choke and Kill Hose,BOP Well-Control Hose.

API Oil Drill Hose - LETONE's preferred hose, has achieved API petroleum certification. Suitable for drilling platforms, semi-submersible drilling rigs or drilling rigs relative motion, drilling rig installation size changes and other parts of the connection, transportation of oil, gas, mud and other high-pressure medium.


API Oil Drilling Hose

The Type of Fitting

The fitting adopts patent design

Selection of Inner rubber

According to the life of using, choose the right rubber: NBR synthetic rubber (one year life) , HNBR (probationary period of three years) , PFA (use of five years).

API oil drilling hose production and application

The product is technologically advanced and adaptable. In 2002, it was listed as a Torch Program by the State. It can last for more than 5 minutes under the working pressure of 1093 ℃ (2000 ℉) flame temperature.

Performance Characteristics

The pipe body has the characteristics of high pressure resistance, heat insulation, flame retardant and fire resistance, etc., and the inner wall is highly wear-resistant. The pipe body has the advantages of no resistance and long service life, and is adapt to the soft connection of the blowout preventer pipeline inside and outside the wellsite and the soft connection of the choke and kill hose.
