The zhengkang Press Fitting System in carbon steel is indicated for use in various types of civil and industrial installations where the stainless steel pipework is not required.
Typical applications are:
- closed-circuit water heating and cooling systems
- compressed air and inert gas systems
- sprinkler systems
The o-ring gaskets, made of black EPDM, are resistant to aging,
heat and chemical additives and are therefore particularly suitable
for all types of treated water.
Conditions of use
- Maximum operating pressure: 16 bar
- Operating temperature: - 20 °C + 85 °C
- Maximum temperature: 120 °C

According to authoritative sources, although the overall plan for the non-ferrous industry will not become a part of the national “Twelfth Five-Year Planâ€, the rare metals industry in the non-ferrous metal sector will appear as an independent part in national planning for tungsten, molybdenum, tin, The development goals and directions of five rare metals such as antimony and rare earth are required. In addition, “rare metal production and operation practices†are being drafted.
China Nonferrous Metals Industry Association estimates that the apparent consumption of four basic metals in China will reach 43.8 million tons in 2015. Among them: 8.3 million tons of copper, 24 million tons of aluminum, 5 million tons of lead and 6.5 million tons of zinc. According to the draft, in the next five years, the non-ferrous metals industry will mainly meet the domestic market demand based on domestic and international energy, resources and environment conditions, make full use of domestic and foreign mineral resources, vigorously develop circular economy, and strictly control the blind expansion of smelting capacity. ,Eliminate backward production capacity. It is planned that by 2015, the crude copper smelting control will be less than 5 million tons, the electrolytic copper will be controlled between 6.5 million and 7 million tons, the alumina will be controlled within 41 million tons, and the electrolytic aluminum will be controlled within 20 million tons. The lead smelting control will be Within 5.5 million tons, zinc smelting is controlled within 6.7 million tons. According to industry insiders, from the perspective of numbers, the future expansion of total non-ferrous metal smelting capacity will be quite limited.
In terms of resource self-sufficiency rate, the planning requirements, through domestic development and foreign mineral resources cooperation, strive to achieve 40%, 80% and 50% of China's copper, aluminum and zinc mineral raw materials in 2015. Recycled refined copper and recycled aluminum, recycled lead production accounted for 40%, 30% and 30% of refined copper, electrolytic aluminum and refined lead production.
In terms of improving concentration, the plan requires that by 2015, the top 10 enterprises in copper, aluminum, lead and zinc account for 90%, 90%, 70% and 70% of the total national production respectively. It is recommended that the country continue to encourage the development of local large enterprise groups.
The plan encourages the development of some deep processing, new technologies and new materials projects. According to the plan, by 2015, a number of high-end products will be formed, including 600,000 tons of high-precision copper strips, 850,000 tons of precision copper tubes, and 500,000 tons of electrolytic copper foil. The development of industrial aluminum materials will be basically satisfied in 2015. Domestic demand. Focus on research and development of light and high-strength structural materials, information functional materials, high-purity materials, rare earth materials, military supporting materials and other equipment technologies and industrialization technologies that meet the needs of national economic development.
According to the authoritative sources mentioned above, the Ministry of Industry and Information Technology is drafting the “Twelfth Five-Year Plan†for the rare metals industry, which will be independent of non-ferrous metal planning and has a higher level. Rare metal planning will involve five rare metal varieties of tungsten, molybdenum, tin, antimony and rare earth. The plan mainly includes total control, determining income targets, profit and tax targets, and focusing on encouraging development directions. Taking the tungsten industry as an example, six key development areas have been established, including cemented carbide deep processing, tungsten-based high-performance alloys, special performance tungsten wire, and equipment manufacturing processing aids.

Specifications
The 12th Five-Year Plan for Nonferrous Metals is released to control the production of ten metals
Shang Fushan, vice president of China Nonferrous Metals Industry Association, disclosed the draft of the “Twelfth Five-Year Plan†for non-ferrous metals industry for the first time at the “2010 China Copper and Cobalt Resources Summit Forum†held on the 23rd. According to the plan, by 2015, the output of ten non-ferrous metals (copper, aluminum, lead, zinc, nickel, tin, antimony, magnesium, titanium sponge, mercury) will be controlled within 41 million tons.
The special process used to make the press fittings can be broken down into the following main stages:
- cutting the pipe into sections and mechanical working
- forming the toroidal seat
- any welding of other parts of the fitting
- any annealing heat treatments
- galvanising surface treatments
