Basic Principles and System Composition

Basic Working Principle

Line pipes are connected into a complete pipeline, using the pressure difference from the first station to push oil and gas to flow directionally, relying on high strength and sealing to prevent leakage, adapting to conditions, ensuring safe and efficient oil and gas transportation.

Overall System Composition

Line Pipe Main Body Unit: Including various pipe bodies, joints, welding interfaces, core transportation carrier; Connection and Sealing Unit: Including welding equipment, threaded joints, sealant, realizing sealed connection; Booster Transportation Unit: Including booster pump stations and compressors, providing transportation power; Protection Supporting Unit: Including anti-corrosion coating, cathodic protection, thermal insulation layer, extending service life; Detection and Maintenance Unit: Including pressure sensors, leak detectors, pigging equipment, ensuring safe operation and maintenance.

Basic Principles and System Composition

Pre-operation Preparation: Determine working conditions, select line pipes, inspect pipe body and welding quality. On-site Preparation: Clean line pipes, pre-treat interfaces, commission various equipment. Pipeline Laying: Lay pipes according to the scheme, connect and seal section by section, and do interface protection. Pressure Test and Commissioning: Conduct hydrostatic/pneumatic pressure test, commission booster and monitoring system. Commissioning and Operation: Put into operation after passing the test, monitor in real time, and conduct regular maintenance and troubleshooting.
