The scope and technical conditions of the leak plugging industry under pressure:

Main technical principles:

Under the condition of keeping the production conditions unchanged, use clamps to contain the leakage point, establish a new sealed cavity, inject a special sealant with a thrust higher than the medium pressure of the leaking system, and achieve sufficient sealing specific pressure in the sealed cavity to prevent leakage , Forming a new and reliable sealing structure.

Process principle:

Dongxin leak plugging technology under pressure:

Xi'an Dongxin Petroleum Equipment Factory Co., Ltd. has implemented safety protection operations for oil and gas and other pressure fluid pipelines for a long time.
Among them, technologies such as valve replacement under pressure, maintenance under pressure, and leak plugging under pressure cover various pressure operations; leak plugging under pressure is mainly aimed at gas trees and pipelines in oil and gas fields, and carries out targeted related construction operations for various types of leakage. Eliminate safety hazards.

Advantages of Dongxin Petroleum leak plugging under pressure:
1. Applicability: Design for different working conditions (design of tooling, sealing, glue injection process)
2. Safety: conduct simulation tests on the designed tooling on the basis of the same working conditions
3. Reliability: According to the corrosion situation and pressure level, select suitable leak-proofing and injecting materials and design the corresponding construction technology (close tracking, 24-48 hours for rechecking and repairing)

On-site operation process:
