Reducers are tube fittings that are widely used in a number of industries in order to provideing greatest connection flexibility in connecting fractional tubes in various installations. Pipe reducer is a kind of pipe fitting that joins two pipes of different diameter.The pipe reducers are available in a range of materials depending on the end use of the products and these fittings are manufactured in inch and metric size. Reducers are special type of tube fittings that are commonly used in the demanding environments of chemical and power plants. They provide a highly reliable, sturdy and tight integral line system and these type of pipe fittings remain unaffected by shock, vibration or thermal distorion. These pipe fittings are very easy to install and they resist leakage due to thermal or pressure cycling. These reducers are sometimes chrome or nickel coated to prevent corrosion and increase the lile of the product.
An Eccentric reducer, also called a Bell reducer, has two female (inside) threads of different sizes with centers so designed that when they are joined, the two pieces of pipe are not in line with each other, but they can be installed so as to provide optimum drainage of the line.
Used of pipe reducer: A pipe reducer the two basic purposes: Changing the pipe diameter Handling the expansion, misalignment or vibration problem
JH STEEL, Now and Tomorrow
JH STEEL is a Korean company which is a professional supplier and distributor of fittings, flanges and related items-valves, pipes, tubes etc.
We had entered Chinese market to follow the trend of globalization, and we have our own plants in both Korea and China.
