Production of stainless taps
GOST 17 375−2001 regulates geometry of taps, standard sizes, bend radius (usually R=1,5D), steel grade and application — up to 100 atm. As a rule, domestic stainless steel taps are seamless with thick walls. Imported stainless elbows are made of electric-welded pipes and have a seam which is invisible from outside, but easily detected inside. Compared to seamless taps, the walls of imported ones are thinner at the same diameter and can withstand less pressure. For production use steel grades — 12X18H10T, 304 AISI, 304L AISI, less often: 10X17H13M2T, 316 AISI, etc.

Application
Bends have bend angles of 45, 60, 90, 180 degrees (other angles may be made under the order), but the most typical bend is 90 °.
In pipelines, bends separate streams of working fluid or gas. In construction and interior buildings they join pipes, if necessary to change the spatial position of the structure. Stainless steel bends are widely demanded in the food, pharmaceutical, chemical industry, especially in pipelines with aggressive working environments. Stainless steel bends with threaded connections are used in sanitary and other pipelines through which water flows. The diameter of these branches from DN 6 (1/8″) to DN 100 (4″), They have internal threads on the ends (BP-BP type) or internal on one end and external on the other (BP-HP). In construction, interiors of buildings more often use imported stainless steel taps — they have a more beautiful appearance (all clarified) and a variety of surface treatments. The most common surface is matt, but polished and mirror (polished) surfaces are also used. These branches with special treatment surfaces are wrapped in film to keep the shipment or installation.
