Upholding the corporate spirit of “Integrity, Harmony, Pragmatism, and Innovation,” we remain committed to a business philosophy that puts people first, embraces technological innovation, and emphasizes integrity and pragmatism.
Let me introduce what “big-head and small-head” is.

What are the types of reducers? Reducers, also known as reducing tees or eccentric reducers, are one type of chemical pipe fitting used to connect two pipes with different diameters. Depending on their shape, they can be classified into concentric reducers and eccentric reducers. The materials used for reducers include stainless steel reducers (as well as alloy steel and carbon steel reducers). Common materials for reducers include No. 20 steel, Q235, Q345, and 16Mn.
What are the types of eccentric reducers? Eccentric reducers, reducing tees, and eccentric concentric reducers—these are chemical pipe fittings used to connect pipes of two different diameters. Depending on their shape, they can be categorized into concentric eccentric reducers and eccentric eccentric reducers. The materials used for eccentric reducers include stainless steel eccentric reducers (as well as alloy steel and carbon steel eccentric reducers). Common materials for eccentric reducers include No. 20 steel, Q235, Q345, and 16Mn.
We offer flanges and tube sheets that comply with various standards, including U.S. standards, British standards, and a wide range of non-standard specifications. Our products also meet the relevant standards for pressure vessels as specified by the Ministry of Power, such as the mechanical industry standards and the petrochemical industry standards (SH3406-1996), as well as marine standards and chemical industry standards (HG/T5010-1958, HG/T20592-2009, etc.). The raw materials used for forged steel flanges exported to overseas markets conform to the U.S. ASTM A105 standard.
What is meant by “eccentricity”? The quality of the eccentric reducer shall comply with the provisions of the current regional standard “Steel Butt-Welded Seamless Pipe Fittings” GB/T 12459-2005 and shall also meet the following requirements: The appearance of the eccentric reducing pipe shall be free from cracks and laps, and its wall thickness shall be greater than that of the larger-diameter end section.
The roundness of eccentric reducers shall not exceed 1% of the corresponding outer diameter at either end, with an allowable tolerance of ±3 mm. For concentric reducers, the centerlines at both ends must coincide, and the allowable tolerance for eccentricity is ±5 mm. The dimensional tolerances for eccentric reducers shall comply with the provisions given in Table 4.2.2-3.
