The biggest advantage steel pipe can be 100% recycled, environmentally friendly, energy-saving, resource conservation national strategy, national policy to encourage the expansion of high-pressure alloy pipe applications. At present, the proportion of the total accounted for steel alloy pipe of the developed countries consume only half the field of the use of alloy tubes expanded to provide a broader space for development of the industry. According to the research branch of China Steel Association alloy tube expert group, with an average annual growth of China's future demand for long steel, high alloy pipe up to 10-12%. Shandong Liaocheng Polygram Pipe Manufacturing Co., Ltd. is China Petroleum & Chemical Corporation supplies and equipment designated by the Ministry of China Petrochemical alloy steel pipe distribution center, China National Petroleum Corporation a supply network companies. Professional management of various imports, domestic steel, stainless steel, carbon steel pipe, plate, bar, profiles, pipe fittings and welding materials, to provide support (pipe fittings) materials for the petroleum, chemical and power industries. The company's main pipe imports from Japan, the European organizations,, JFE China Jiangsu agents, and establish long-term friendly relations of cooperation with Japan's Sumitomo joint venture with the German units DMV and 蒂森曼内斯曼 companies. Simultaneously with domestic Shanghai Baoshan Iron and Steel, Panzhihua Iron and Steel Group, Chengdu, Tianjin Seamless Steel Tube Plant, Hengyang Steel, WSP, Zhenda Steel Plant, Jiang Yin Zhangjiang Group and other large enterprises to establish a good business relationship, 2003 as Chengdu Iron & Steel Co., Ltd. high-pressure steel pipe China market sales agent. Good reputation, smooth purchase channels, in strict accordance with design requirements and technical standards would like to provide users with different materials, different specifications of the various materials. Large indoor warehouse can store more than 8,000 tons, all year round with all kinds of steel pipe, stainless steel and other steel materials, more than 5000 tons. The company's sales for three consecutive years in order to continue to grow more than 30% of the rate, 2007 may be more than 200 million yuan. The company is equipped with a full range of physical, chemical and mechanical properties testing equipment, has made non-destructive testing and certification and boiler tubes to generate a license; passed the ISO9001: 2000 quality system certification; Liaocheng City contract and trustworthy enterprises, banks AAA credit enterprise. Threaded seamless steel pipe (referred to as the female) refers to an inner wall of the spiral groove processed into seamless steel pipe. Currently in our own design or abroad 300MW, 600MW and above capacity subcritical and supercritical thermal power boiler, membrane water wall tube widely used within the thread. Compared with ordinary light pipe, threaded pipe can effectively prevent the vapor film is formed between the water and the pipe wall, increasing the light pipe flow disturbance, so that the wall temperature is more uniform, both to avoid the light pipe burn, but also improves the boiler The heat transfer efficiency. Number of thread threaded pipe according to need four, six, eight dollars, the main materials are 20G, SA210C, T2, T12,12Cr1MoVG, 15CrMoG, T22, T23, etc., China's annual required threaded pipe 2.5 ~ 30,000 tons. In order to meet the needs of large-capacity subcritical and supercritical (ultra) supercritical boiler development, Tianjin Pipe Group Co., Ltd. (Tianjin Pipe) using Φ150mm casting tube, there are three roll Pipe Mill Φ168mmPQF provide Φ76mmx9mm shortage tube, through independent welded steel pipe manufacturers die design, successfully developed 15CrMoG material 8 Φ51mmx5.7mm threaded high-pressure boiler tube. The technical requirements of the female threaded high-pressure boiler tube should reach addition to general technical requirements of the light pipe steel pipe manufacturers, but also according to GB / T 20409-2006 "high-pressure boiler seamless steel pipe with threaded" standards or each boiler manufacturing plant procurement practices, their size and thread parameter deviations have different requirements. Such as cold-rolled stainless steel plant in Tianjin Pipe material developed 15CrMoG 8 Φ51mmx5.7mm threaded high-pressure boiler pipe, its technical requirements in Table 1.
