The large stainless steel head is also called a different diameter tube, which is used to connect different sizes of pipes. Generally, it is divided into two kinds of concentric and eccentric tube. When the projection of the two port is concentric circle after the tube is set up, it is called the concentric tube, and the projection of the eccentric tube is the inner circle of the small circle.
The sizes and sizes of pipes are different, and the industries that are connected with them are also different.
In the power, mine, metallurgy and other industries, the transport and output of materials are transported by close and high pressure. The pipeline is subjected to considerable pressure and is subjected to very serious wear and tear. A single material pipe is difficult to meet the requirements of this working condition.
Especially for the elbow, the size of the head and other fittings, because of its safety and service life, the emphasis is on improving the toughness, impact resistance and wear resistance of the lining of the pipe. At the same time, we should also consider the overall strength of pipes and elbow.
Before the big head is bonded, use dry cloth to wipe the side of the socket and the outside of the socket. When the surface is sticky with oil, it must be cleaned with acetone, and the following points should be paid attention to:
1, diameter: DIN standard (DN10-DN150), 3A/IDF (1/2 -6), ISO (diameter of 12.7- with 152.4);
2, international industrial standard: DIN, ISO, SMS, 3A, IDF and so on.
3, product materials: 316, 316L;
4, quality and use: the big head and outside with high-grade polishing equipment to meet the surface precision requirements; this product is suitable for dairy, food, beer, beverage, pharmaceutical, cosmetics and other industrial fields;
5, external processing: we can map and sample non-standard products according to user requirements.
6, connection mode: clamp (fast mounting), welding type, threaded connection.
