Pipeline
Construction

FLEES GLOBAL is a renowned indigenous 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 its 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 Chinese and international standards.

Pipeline Anti-Corrosion Work

FLEES GLOBAL 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 7km of PE anti-corrosion work, 7km of FBE anti-corrosion work, and 5km of inner coating.

Inner coating of pipelines: Depending on the transported medium, the inner coating of pipelines may be divided into two types-drag-reduction and anti-corrosion. Anti-corrosion inner coating is mainly used to extend the service life of pipelines, and it requires field coating for welded joints; drag-reduction inner coating is mainly used to improve the transportation efficiency of the transported medium, thereby reducing the investment and operational costs, and it does not need field coating for welded joints.

CW Series of Acid Pickling and Acidizing Corrosion Inhibitors: In industrial production, corrosion inhibitors are widely used as protective additives to avoid corrosion on metallic materials which are pickled to remove their metallic oxidant and deposit layers. Acid pickling is a process in which corrosion outcomes and deposit layers are chemically dissolved and converted into soluble substances by an acid liquid. Then these substances detach from the equipment surface and flow away in the waste liquid. The CW Series contains compounds of organic amine. As they inhibit both the anode and cathode processes on the metallic surface, they are hybrid inhibitors.
