Описание

The pressure-bearing and pressure-controlling parts are made from forged, the chamber of body appear the oval on the longitudinal section of vertical Поршень Шток. Use ram to Открытый and close by the hydraulic Цилиндр drive the Поршень Шток. The movement of bonnet is linear type, the movement of bonnet is controlled by two hydraulic Цилиндр, it is designed the auto sand-cleaning structure on the body. On the intermediate flange, design the secondary seal unit, under the emergency case, if it is observed the fluid flow out by viewport, it can inject the grease urgently.  The type U BOPs have sold to North America, South Asia and got good quality feedback.

Особенность

◆ Давление-bearing parts and pressure-controlling parts are forged. The structure of these parts are densified and has high strength, which ensures that they are used more safely and reliably.
The ram chamber is oval cross-section, which can reduce the stress of body and increase the bearing capacity of body.
◆ Открытый the bonnet assembly to change ram by oil pressure. It can reduce the labor intensity of employee and improve the working efficiency.
◆ Shear ram is equipped with auxiliary hydraulic Цилиндр, which has no impact on function but smaller volume. It is also equipped with big hydraulic Цилиндр, which has simple, safe and reliable structure.
◆ For all position of high sulfur resistant ПВО which are contacting well fluid are overlaid with high nickel base alloy, they can achieve the effect of H2S resistance. ( according to the remand of clients)
◆ The company is able to manufacture completed series of type U ПВО and parts.
◆ The parts of ПВО have strong interchangeability.
