Why the Coating Steel Pipe is So Durable?

Paint is the most commonly used material to protect steel. Paint systems for steel structures have developed over the years to comply with industrial environmental legislation and in response to demands from bridge and building owners for improved durability performance. Otherwise, coating steel pipes must be carefully selected to provide sufficient durability to meet the requirements of the service environment and its associated operating conditions.Some coat systems have been replaced by typically three coat alternatives, and the latest formulations have focused on application in even fewer numbers of coats, but with increasing individual film thickness. Examples of this are epoxy and polyester glass flake coatings that are designed for high build thickness in one or two coat applications, and single coat high build elastomeric urethane coatings, up to 1000μm thick.Modern specifications usually comprise a sequential coating application of paints or alternatively paints applied over metal coatings to form a ‘duplex’ coating system. The protective paint systems usually consist of primer, undercoat(s) and finish coats. Each coating ‘layer’ in any protective system has a specific function. Hunan Great Steel Pipe Co.,Ltd pays more attention to in the pipeline engineering research areas as a pioneer of China Petroleum Pipeline & Gas Pipeline Science Research Institute, Such as: the use of oil and gas pipelines, pipe welding technology innovation, high-end plumbing materials research and development, as well as special tools technological innovation pipeline construction, pipeline corrosion protection science and technology research, science and technology research pipeline non-destructive testing, pipeline quality assessment, and research pipeline standards and so on. In the future, we will try to use new technology to create new business value and to contribute to research and product development for the pipeline. Our main products include: carbon steel seamless pipe, welded steel pipe, stainless steel pipe, coating steel pipe, which is variety types and full range specifications, moreover, strictly in accordance with international standards, like: ISO certification, CE certification.
