Rongsheng Company has an advanced production line of rubber sealing products, which is equipped with physical analysis, mechanical performance testing, stepping high and low-temperature test devices, simulated deep-water environment test devices, special pressure test devices for factory tests, and other detection and test methods. It can develop rubber sealing products for petroleum machinery that are suitable for different working conditions such as high temperature, low temperature, high hydrogen sulfide, and so on.

At present, Rongsheng Company has developed a series of rubber sealing products matching its own BOP series products. It can produce spherical rubber core and conical rubber core of various annular blowout preventers with drift diameters from 4 3/4" to 29 7/8" and pressure ratings from 3000Psi-15000Psi; Various specifications of variable ram, shear ram, and pipe ram seals; Rotary BOP series seals; And other petroleum machinery seal products.

RS Ram BOP VBR

The variable diameter ram assembly consists of small variable ram assembly and large variable ram assembly, which can seal pipe strings of various specifications. The range of small variable ram sealing string is not more than 2 inches, the range of large variable ram assembly sealing string can be more than 4 inches, and the maximum sealing pressure rating can be up to 20000 psi. The variable ram assembly can realize the sealing of pipe strings of different specifications within a certain range, reduce the number of ram replacements on site, and improve the efficiency and benefit of drilling operations.

RS H2S Resistant Shear Ram

Shear ram is a key component of ram BOP. In case of blowout and other emergencies, timely cut the drill pipe in the wellbore to shut the well and avoid damage to equipment, personnel and environment.

The ram and blade body of anti-H2S shear ram are made of intrinsically sulfur resistant materials. Reliable performance in H2S environment, and the shear blade can be replaced separately. Double V-shaped cutting edge is adopted, with strong shearing ability.
