Why to use galvanized steel pipe for pipeline in oil and gas industry

In the recent years, galvanized steel pipe has been widely used for pipeline in oil and gas industry. The main points concerning the durability of steel as it affects pipeline safety are as follows. Firstly, the steel itself does not degrade with the passage of time. Eighty-year-old pipe, if properly protected, exhibits the same properties if tested today as it would have if tested 80 years age. Secondly, while the lower initial performance characteristics of older materials and their possible exposure to in-service degradation (before cathodic protection, for instance) is a concern, current inspections and/or testing of pipelines comprised of older materials are used to detect potential problems before failure. Thirdly, the continued satisfactory performance of any pipeline, old or new, requires levels of inspection and maintenance appropriate to the performance characteristics of the materials and the severity of degrading factors to which the pipeline has been exposed in its operating environment. Finally, new technology can identify and characterize ever-smaller defects, thus improving performance further.

Round steel pipe is the popular type of hollow section tubes in the current steel pipe market that is widely used for pipeline in oil and gas industry for many years. With reference to the specifications of round tube, there exists further division. As a rule, there tends towards the steel pipe diameter to make a distinction between steel pipes according the international standards. Specifically speaking, round pipe specifications mainly depend on the inner diameter, while square pipe specifications are mainly determined according to the inner size of the pipe cross section. In view of the same specification, China steel pipe manufacturers will assume more material costs of square steel pipe in comparison with round steel pipe. In addition, in the face of various changes in the steel pipe market, China steel pipe manufacturers try to make the reasonable arrangement of steel pipe production capacity based on the different objective conditions between different types of steel pipes, in order to better meet the various needs of the steel pipe market.

In most cases, there are a few commercial issues under considerations. Budget can be a big factor, but when it comes to choosing the best material for the job at hand, there are many other things to consider before you place your order. Cold rolled steel pipe generally has the rational cost effective in the market. Compared with other typical steel pipe coatings, such as specialized painting and powder coating, galvanization is much more labor-intensive, resulting in a higher initial cost for contractors. Besides, due to its durability and anti-corrosive properties, galvanized steel pipe can recycled and reused, which to some degree save a lot of money during the post maintenance work.
