The size head is also called a reducer, which is used to connect pipes of different sizes. Generally, it is divided into two types: concentric reducer and eccentric reducer. When the different diameter pipe is set up, the projection of the two ports is concentric, then it It is called a concentric reducer, and the projection of the eccentric reducer is a small circle inscribed in the outer circle.
Different sizes of heads and tubes are also available in different industries. In the power, mining, metallurgical and other industries, the transportation and output of materials are carried out at close range and high pressure. The pipeline is subjected to considerable pressure and is subject to severe wear. It is difficult to meet the requirements of this material. Requirements, especially elbows, heads and other pipe fittings, due to their safety and service life, focus on improving the toughness, impact resistance, and wear resistance of the pipe liner. Also consider the overall strength of the pipe and elbow.
Before bonding the size head, apply a dry cloth to wipe the socket side and the outside of the socket. When the surface is sticky with oil, wipe it with acetone. Note the following:
1. Control caliber: DIN standard (DN10-DN150), 3A/IDF standard (1/2"-6"), ISO standard (Ф12.7-Ф152.4);
2. International industrial standards: DIN, ISO, SMS, 3A, IDF, etc.;
3. Product materials: stainless steel 304, 316, 316L;
4, quality and use: the inside and outside of the head with high-grade polishing equipment to achieve surface precision requirements; this product is suitable for dairy, food, beer, beverage, pharmaceutical, cosmetics and other industrial fields;
5, external processing: according to user requirements to map, sample processing non-standard products;
6, connection method: clamp (fast loading), welding, thread (live) type.
