Pipeline

TCCL is a renowned contractor in the survey, design, consultation, procurement, construction and management of long-distance pipelines and their auxiliaries, as well as medium-to-large storage tank works. We provide national and foreign customers with engineering services for pipelines used to transport different medium such as crude oil, natural gas, refined products, LPG, coal gas, nitrogen, oxygen, water, ethylene, coal and ore slurry, engineering services for oil and gas storage, and technical services for oil and gas storage and transportation, in compliance with international standards.

We can install pipelines in different conditions such as mountains, deserts, plateau, tundra, swamps, hydrographic net, and collapsible loess. We are experienced in advanced technologies including semi-automatic pipeline welding, all-position automatic welding, and all-position internal welding. We have a sophisticated quality management system, HSE system, OSH (Occupational Safety and Health) system, and operational specifications.

TCCL has multiple world-leading operation lines, which can build a composite tri-layer anti-corrosion structure externally on steel pipes, or externally apply coal-tar enamel for anti-corrosion purposes, or internally apply coatings on steel pipes. Therefore, we can undertake tri-layer PP or PE anti-corrosion work, FBE (Fusion Bonded Epoxy) coating, and application of coal-tar enamel for anti-corrosion purposes. In addition, we can carry out anti-corrosion and heat-preservation work on other containers such as metallic storage and transportation containers and metallic gas tanks, as well as metallic anti-corrosion structures. Every day, we can accomplish 12 km of PE anti-corrosion work, 12 km of FBE anti-corrosion work, and 10 km of inner coating.
