Welded pipe fittings finished with buff polishing.

For buff finish polished welded pipe fittings, please consult Benkan Kiko.

There are cases where "polishing" is applied as a surface finish specification requirement for welded pipe fittings, and particularly for stainless steel products, there is a smooth, glossy finish achieved through "buff polishing." "Buff polishing" is a method that uses a polishing tool equipped with cotton, felt, or wool called a "buff," along with a paste-like abrasive material, to smooth the surface, especially when a mirror finish is required. Buff polishing has classifications of "roughness," expressed as a specific number finish. Generally, the larger the number, the higher the grade, resulting in a glossier product surface. At Benkan Kiko, regardless of buff polishing finish, we accommodate surface grade specifications not only with abrasive particle sizes but also with surface roughness parameters (Ra, Rmax, etc.), roughness symbols, evaluations using comparison test pieces, and assessments using surface roughness gauges, allowing us to meet surface grade requirements tailored to specific applications. If polishing is required for welded pipe fittings in your piping design, please feel free to contact us. <Varieties> - Elbows, T-pieces, reducers, caps, stub ends <Materials> - We can accommodate various materials including SUS304, SUS304L, SUS316, SUS316L, and others.

basic information

Buff polishing is mainly performed on stainless steel products in pipe fitting products. The effects include the removal of irregularities caused by the molding process, as well as the reduction of adhesion of contaminants, and the reduction of fluid resistance due to pressure loss. It can be applied to both the inner and outer surfaces of the product. Please contact us separately for information on available sizes. Sample products are compared with buffing grades of 200, 300, 400, and 600.
