So far, as it is well acknowledged, welded steel pipe production growth rate seems faster than the growth rate of the seamless steel pipe; proportionately is much larger than the seamless steel tubes welded steel production in the current market. In the type of welded steel pipe, ERW welded steel pipe in the dominant position on the yield, but also in the oil and gas pipeline, LSAW and spiral submerged arc welded pipe vying for market share within the field of use of city gas pipeline. Steel pipe as an important part of the iron and steel products, play a major role in national economic development, manufacturing process and the tube shape is divided into seamless steel pipe, straight seam steel pipes, spiral welded pipe, round steel pipe, square steel pipe and rectangular steel pipe.
When it comes to galvanized steel pipe, it is believed that we all have a prior basic knowledge about this common type of pipes through various information on the internet. Hot dipped galvanized steel pipeis the one common type. Generally speaking, just by its literal meaning simply, we will have the rough idea that zinc and steel are the major two components for a complete steel pipe. Since these two mental elements have distinctive physical and chemical property, it is suggested that they should not occur alone and can not be used separately. As a rule, they are combined together to improve stability & durability of products. With reference to steel pipe price, there tends upwards recently. As it is acknowledged, steel pipe pricing is subject to lots of varying factors, including rawmaterial cost, manufacturing technique complexity, market supply&demand as well as national economic policies and so all. For example, in 2008, considering raw materials such as iron ore prices grew, China had to reluctantly agree to price increases by the three largest iron ore producers in the world. As a result, there seems a headache for pipe users to purchase relativewelded steel pipes per as their desired pricing.
With a new round of economic growth under China’s recent introduction of a series of new economic policies, the prospect of steel pipe industry in China somewhat makes some progress. China, as the major steel pipe supplier in the world is playing a more and more significant role in the export of steel pipe to other countries around the world.
