Product Introduction
Long-Distance Pipeline is the core equipment of oil and gas storage and transportation engineering. It is mainly used for the long-distance transportation of fluid media such as crude oil, natural gas and refined oil. Through the coordinated operation of the pipeline body and supporting systems, it realizes the safe, efficient and continuous transportation of oil and gas media, and is widely applied in scenarios such as cross-regional oil and gas storage and transportation, transnational energy transportation, and coastal oil and gas gathering and transportation.
Types and Characteristics of Equipment
Type
Oil and Gas Long-Distance Pipeline: Suitable for onshore trunk line transportation, transnational energy corridors and coastal pipe network gathering and transportation, it features high pressure resistance and strong corrosion resistance. With an integrated pipe body design, it has a complete range of diameter specifications, high transportation efficiency, and adapts to the demand for long-distance and large-flow oil and gas transportation, making it the core carrier of cross-regional energy allocation.
Features
Features
Large-diameter and high-pressure design with large transportation flow to meet the core demand of long-distance energy allocation. The pipe body is made of anti-corrosion, anti-cracking and temperature-resistant materials to adapt to the transportation requirements of different media (crude oil/natural gas/refined oil). The flexible model can adapt to terrain deformation and geological activities, with strong deployment adaptability in complex environments. Equipped with an intelligent monitoring system to realize real-time perception of pipeline operation status and fault early warning. Laid independently in sections, local maintenance does not affect the overall transportation, with high operation and maintenance efficiency.Long-Distance Pipeline
Long-distance pipelines enable efficient large-scale transmission of oil, gas and refined products across regions.
Long-Distance Pipeline
They feature safe, continuous and low-cost transportation with strong pressure resistance and reliability.
Long-Distance Pipeline
As key energy infrastructure, they ensure stable supply and connect production areas with consumption centers.
Basic Principles and System Composition
Basic Working Principle
The oil and gas medium is pressurized by the booster pump station at the first station, and the pressure difference in the pipeline is used to drive the medium to flow directionally and continuously in the pipe body. The intermediate pump station/compressor station is used for supercharging and energy supplement along the way to ensure the medium transportation power; at the same time, the flow, pressure and temperature are regulated through the valve chambers and monitoring stations along the line, and the medium is received, metered and distributed at the distribution station/last station at the end. The leak-free long-distance transportation of oil and gas medium is realized through the sealed pipeline throughout the whole process.
Overall System Composition
Pipeline Body Unit: Steel/flexible pipelines, elbows, tees and other pipe fittings, the core transportation carrier. Booster Power Unit: Centrifugal pumps, compressors, motors, etc., providing power for medium transportation. Regulating Valve Chamber Unit: Stop valves, regulating valves, etc., realizing flow and pressure regulation and emergency shut-off. Intelligent Monitoring System: Pressure/temperature sensors, optical fiber monitoring, UAV inspection, etc., monitoring the operation status in real time.Supporting Auxiliary Unit: Anti-corrosion and thermal insulation layer, cathodic protection system, pigging equipment, metering device, etc.
Basic Principles and System Composition
Pre-operation Preparation: Confirm medium/distance, design route scheme, select pipeline type, inspect material and equipment quality On-site Laying: Excavate/lay pipelines, complete welding and anti-corrosion insulation, install stations and monitoring equipment, and ensure fixation and protection. Commissioning and Operation: After pigging and drying, the first station boosts pressure to transport media, adjust parameters in real time to ensure continuous transportation Post-operation Maintenance: Regular detection, pigging and anti-corrosion maintenance, patrol and troubleshooting, record and analyze operation data.
