In construction engineering, engineering is a common construction task, and in some cases, it is necessary to carry out construction with pressure closure. Sealing with pressure refers to the need to block the pipeline or equipment during the construction
Sealing with pressure is a common engineering technology, widely used in petroleum, gas, cement, chemical industry and so on. It refers to the application of external pressure to fill the material into a specific part of the pipe or equipment,
The packaging requirements with pressure closure mean that during the package design and manufacturing process, it must be considered that the product needs to withstand a certain pressure during transportation and storage and remain sealed to ensure the
Pressure plugging is a common pipeline maintenance and repair technique that can be used to plug and repair pipelines without interrupting production. Its principle is to plug the pipe or repair the hole in the pipe by inserting a strip expansion bod
Hot tapping machine, also known as pressure tapping machine or drill machine, is an essential tool for performing maintenance and modifications on pipelines. It allows operators to drill into a live pipeline without disrupting the flow of the product. Th
Atos is a leading manufacturer of hydraulic components, including sandwich valves. Atos sandwich valves are designed to control the flow of fluid in hydraulic systems, providing precise and reliable performance in a range of applications.
A hot tap sandwich valve is a type of valve used for tapping into an existing pipeline without interrupting the flow of fluid. The valve is designed to be installed on a pressurized pipeline, allowing for new connections or modifications to be made withou
1. According to physical and mechanical means, plugging can be divided into hanging type plugging, bucket type plugging, folding type plugging, bag type plugging and other forms 2. Plugging is divided into stop plugging and stop plugging according to whe
Our r work of pipeline repair must be based on a deep enough understanding of the pipeline repair business, and for the nationwide pipeline repair technology research. In the process of completing the rush repair work, we can also combine from all aspects
Characteristics and applicability of repair in pipelines Corrosion resistance: non-metallic corrosion resistance; Self-pressure: bare pipe pressure 1.6MPa, sea breaking pressure 4.8MPa; Applying L fast: applying 1 speed seat 300-400 m/h; Overbend: One pas
B-type sleeve repair technology Advantage B-type sleeve repair consists of a pair of semi-circular steel guard plates covering the defects of the pipeline, which are welded together by longitudinal butt weld and the whole set of short ends are fixed on th
