The market condition of expansion joint of stainless steel hardware

Stainless steel expansion joint has cost as a result of raw material tall, useful in pipeline system volume is not very large, if be general medium, multi-purpose carbolic steel as raw material, and stainless steel material is qualitative multi-purpose at high pressure, high temperature and anticorrosion conduit. Stainless steel expansion joint uses the join means of double flange more, its malady depends on: If not be same,connective material pledges if kind of material is qualitative, it is easy when conduit butt joint to if use,solder connection is bad, appear slack phenomenon, so double flange join is best choice.

We are in old real work, the most commonly used model is VSSJA-2 model most practical, stainless steel expansion joint is join of both sides flange, have the effect of spacing, its advantage is can free inside adjustable quantity adjustable, once this arrived adjustable quantity, with respect to the effect that can have spacing, the application of stainless steel expansion joint in conduit is most so wide.

Stainless steel expansion joint is the pipe joint of a kind of metal that uses stainless steel material to be produced character, can have as a result of stainless steel anti-corrosive, be able to bear or endure high pressure, high temperature resistant, installation is convenient, craft is simple, wholesome environmental protection, security is good wait for a characteristic. Use extensively at all sorts of chemical industry conduit so. Stainless steel expansion joint basically applies in conduit of domestic chemical industry and municipal project, project of environmental protection water treatment, actuating pressure basically has: 0.6Mpa, 1.0Mpa, 1.6Mpa

For commonly used pressure limits, be more than 1.6Mpa-4.0Mpa basically is join by flange, flange standard is: GB/T9115.7-88, the stainless steel expansion joint of special demand model can pursue treatment makes sure the user is satisfactory.

Hardware is disperse is given priority to, flow is complementary manufacturing industry, produce the process basically is metallic treatment and component to assemble. Hardware makes basically have: Semifinished product is cast, punch is made, machining, treatment link includes to cast, forging, the processing that heat up a watch, raw material is broken up, iron line loses curved, car, mill, plane, grind or Ban gold shapes wait for treatment craft. Hardware kind line of the products is various, norms each different. The hardware that at present data market place manages kind the product shares more than 10 kinds about a hundred kinds of product. Include: Lock kind, shake handshandle kind, door window kind hardware, family decorates metal fittings kind, water warm hardware kind, the building decorates metal fittings kind, tool kind, Weiyu hardware, kitchen hardware. "Because material breed is various, the collocation of different measurement, different color, different specifications, caused certain difficulty to stock management.

Our country's bigger metals market basically distributings to wait for province city in Zhejiang, Jiangsu, Shanghai, Guangdong and Shandong. For instance, zhejiang always city of Electromechanical of hardware of government office of gold of city of trade of Electromechanical of hardware of market of lock of new century of market of metals of Linyi of the group of industry of hardware Electromechanical production of health city, Shandong, Hangzhou, Shanghai, Chengdu, Guangdong is wide city of Buddha hardware Electromechanical. Current, line of business of products of hardware of our country daily expense has crossed world front row. The investigation report that Puhua grinds to release in occupying shows, our country built shave of slide fastener, report to need early or late implement, 14 technologies such as bowl of stainless steel household utensils, iron, razor blade, bicycle lock develop a center, and pressure cooker, dynamoelectric shave is needed implement, the 16 products center such as lighter. Meanwhile, our country also becomes one of big states of the treatment big country of global hardware product and exit stage by stage.
