Stainless steel head and stainless steel elbow, stainless steel tee technology is not the same
Stainless steel head size of the manufacture:
Size of the head (reducer) is used for pipe diameter at a tube. Commonly used in the forming process for the reduction of diameter compression, expansion of the diameter or diameter of the expansion of the press, for some sizes of the reducer can also be used stamping. In this case,
Reduced diameter / expanded diameter forming
Reduced size of the head forming process is the size of the big end of the same diameter of the tube into the mold, in the axial direction along the tube along the press, the metal along the cavity movement and shrink molding. Depending on the size of reducer diameter, divided into a compression molding or repeated compression molding.
In addition to the use of steel pipe as the raw material consumption of the size of the head, the size of the local specifications of the head can also be used steel stamping process to stop consumption. Stamping die used in the shape of the size of reference to the size of the head surface design, with the punching of the steel after the sheet metal stamping stretch forming. In this case,
The size of the first bond before the application of dry cloth and the socket side of the socket side of the wipe handle, when the appearance of sticky oil to be cleaned with acetone wipe, the following points to note:
1, control caliber: DIN specification (DN10-DN150), 3A / IDF specification (1/2 "-6"), ISO specification (肖12.7-肖152.4);
2, the international industrial norms: DIN, ISO, SMS, 3A, IDF, etc.
3, the product information: stainless steel 304,316,316 L;
4, the quality and use: the size of the first internal and external use of high-grade polishing equipment, to meet the requirements of the appearance of fine; this product is suitable for dairy, food, beer, beverage, pharmaceutical, cosmetics and other industrial areas;
5, external processing: the user can request to map, sample processing non-standard products;
6, Connection: Clamp (fast loading) type, welded, threaded (live access) type. In this case,
Pay attention to the size of the head is also suitable for environmental dust removal industry in the pipe diameter, are generally rolled steel cutting and welding, pipe diameter varies, the data are generally hot-rolled coil, the application is very good, can save costs.
