Rongsheng Developed and Manufactured the Ram BOP With the Highest Pressure Level in China Without Bonnet Bolts, Which Was Favored by the Market

On August 26th, FZ28-140 (11"-20000PSI) ram BOP without bonnet bolt independently developed by Rongsheng company successfully passed the user's on-site acceptance. This set of well control products with the highest pressure level in China and the design structure has won the national invention patent. It has convenient operation and stable performance. The time for replacing ram assembly on site has been shortened by more than 8 times, which has been favored and highly praised by users.

FZ28-140(11"-20000PSI) ram BOP without bonnet bolt breaks the design structure of existing similar products at home and abroad, and innovatively adopts the multi-tooth meshing block connection mode, which has strong bearing capacity. The structural design is very suitable for the connection of large diameter and high pressure BOP.Under the witness of National Industrial Well Control Quality and Safety Supervision and Evaluation Center, the product has completed the design validation test according to the requirements of API Spec 16A PR2, and under the witness of Sichuan Kete Testing Technology co., Ltd., it has completed the oil-way air sealing test, 20 ex-factory air sealing tests and 140 MPa air sealing test required by users, and all the tests have passed at one time. It is reported that the operation and maintenance of the BOP with this structure is simple and convenient. When replacing the ram assembly of the BOP, it avoids using special tools to disassemble the operation link of hundreds of kilograms of high torque bolts. Only manual operation can realize the meshing and separation of the block with the body and bonnet. The operation is convenient and labor-saving, and the time is shortened from the previous 60 minutes to about 7 minutes.

Customer feedback is safe and reliable, easy to operate and maintain, which can effectively reduce the labor intensity and is well received and praised by the market. This time, Rongsheng company introduced the structure without bonnet bolt of ram BOP with the highest pressure rating in China to the market, marking that the company has stepped to a new level in the field of well control equipment design and manufacturing.
