With the rapid development of China's economic construction nodal tube processing, increasing consumption of stainless steel tube heat wave section, where the demand for stainless steel pipe also widening, the market prospect. Stainless steel seamless pipe market demand performance on the basis of industry, such as petroleum, chemical, power generation and other festival Shandong wave tube, the demand accounted for one third of the total consumption of stainless steel seamless pipe, as well as automotive, shipbuilding, construction and environmental protection industries also have greater needs. Stainless steel pipe is mainly used for heat exchanger tube, fluid pipe, pressure pipe, mechanical structure tube, urban landscape, such as the industry, the annual consumption of about 700 000 t. Industrial stainless steel pipe demand is high, and mature production technology, currently China's annual industrial stainless steel pipe with a capacity of about 150 000 t around, some still need to import. Made of stainless steel pipe products from the point of view, steel to steel-based TIS body; variety of products: including cold drawn seamless steel, cold-rolled, hot extruded pipe, centrifugal casting pipe, spinning tube; welded pipe include: plasma welding, welding, submerged arc welding speed of light and high-frequency welding pipe, stainless steel pipe can produce substantially covers the world standard varieties and specifications, stainless steel Pipes specifications, up to more than a hundred varieties, Uses involving industrial, civilian fields. Approved standard "lot" means an inspection units, namely the inspection lot. In terms of the delivery unit Batch, said the consignment. When large quantities of delivery, a consignment may consist of several test batches; when delivery is low-volume, a test batch can be divided into several consignment. Form a "batch" usually has the following provisions (see the relevant standard): A, each batch should be the same grade (grade), with the furnace (tank) number or with the mother furnace number, the same size and the same heat treatment system (heats ) steel components. B, for high-quality carbon steel pipe, fluid pipe nodal tube furnace can be different (tank) in the same grade, pipe the same size and the same heat treatment system (heats) composition. C, welded steel pipe by the same batch grades (grade), with the specifications of steel components. High quality steel and high quality steel in GB / T699-1999 and GB / T3077-1999 standard, with behind grade "A" word, serving high quality steel, contrary to general high quality steel. High quality steel in the following part or all of superior quality steel: A, narrowing the scope of ingredients; B, to reduce the harmful elements (such as sulfur, phosphorus, copper) content; C, to ensure a high purity (requires non-metallic inclusion content less); D, ensure high mechanical properties and process performance.
