Best BL Flange products are also called blind plates, and the correct name is flange covers. It is a flange without a hole in the middle, which is used to seal the pipe plug. There are many types of sealing surfaces, including flat surfaces, convex surfaces, concave-convex surfaces, tongue-and-groove surfaces, and ring connection surfaces.

The production process of Best BL Flange products is mainly divided into three types: forging, casting, and cutting.

The Best BL Flange products casted have accurate blank shape and size, small processing volume and low cost, but have casting defects (pores, cracks, inclusions); the internal structure of the casting is poorly streamlined (if it is a cutting part, the streamlined form is even worse); forging Flanges generally have lower carbon content than cast flanges and are not easy to rust. Forgings have better streamline shape, denser structure, and better mechanical properties than cast flanges; if the forging process is improper, there will be large or uneven grains, hardening cracks, and high forging costs. For casting flanges. Forgings can withstand higher shear and tensile forces than castings.

The advantage of casting Best BL Flange products is that it can produce more complex shapes, and the cost is relatively low; the advantage of forgings is that the internal structure is uniform, and there are no harmful defects such as pores and inclusions in castings; the difference between casting flanges and forging methods from the production process There are different flanges, such as centrifugal flanges, which are a type of casting flanges.

Centrifugal Best BL Flange products belong to the precision casting method to produce flanges. Compared with ordinary sand casting, this kind of casting has a much finer structure, and the quality is much improved. It is not easy to have problems such as loose structure, pores, and trachoma.
