With the rapid development of economy in China and the increase consumption of stainless steel, demands for stainless steel pipe also increase. The stainless pipe market prospect is good.
Stainless steel seamless tube market demands come from basic industries, such as petroleum, chemical industry, power generation. These industries’ consumption for stainless steel seamless tubes accounts for one third of the total consumption amount. In addition, there are lots of demands in automobile, shipbuilding, construction, environmental protection, etc.
Stainless steel welded pipe is mainly used for heat exchanger tube, fluid pipe, pressure pipe. The annual consumption is around 700,000 tons in tube mechanical structure, urban landscape, and other industries.
The demand for industrial stainless steel welded pipe is higher. The current welded pipe quantity is about 150,000 tons in stainless steel industry in China. Although our production technology is more mature, some parts of these pipes are still needed to be imported.
According to the domestic stainless steel pipe products
, we often mention the austenitic steel grade. The kinds of products are: seamless steel cold drawn pipe, cold rolled tube, hot extrusion pipe, centrifugal casting tube, and rotary tube. Welded pipes include plasma welding pipe, argon arc welding pipe, submerged arc welding pipe, and high frequency welded pipe. Stainless steel tubes are basically covered the world standard specifications. The specifications of the stainless steel special tube are more than one hundred varieties. The products involve many fields such as industrial and civil field.
But as a whole, varieties, specifications, quantity and other aspects of domestic stainless steel pipe have certain gap with market demands.
