Manufacture of stainless steel taps

GOST 17 375−2001 regulates the geometry of bends, standard sizes, bending radius (most often R = 1.5D), steel grades and field of application up to 100 atm. Domestic stainless bends, as a rule, are seamless with thick walls. Imported stainless steel bends are made from electrically welded pipes and have a seam that is not visible outside the bend, but it is easily identifiable inside. Compared with seamless tap-offs, the walls of the imported pipes are thinner with equal diameters and can withstand less pressure. For production, steel grades — 12Х18Н10Т, 304 AISI, 304L AISI, are used less often: 10Х17Н13М2Т, 316 AISI, etc.

Application

The bends have bending angles of 45, 60, 90, 180 degrees (other angles can be made on request), but the most typical bend is 90 °.

In the pipelines, the outlets separate the flow of working fluid or gas. In the construction and interior of buildings, they connect the pipes, if necessary to change the spatial position of the structure. Stainless bends are in great demand in the food, pharmaceutical, chemical industry, especially in pipelines with aggressive working media. Stainless taps with threaded connections are used in plumbing and other pipelines, through which water flows. The diameters of these bends are from DN 6 (1/8 «) to DN 100 (4»). They have an internal thread at the ends (type BP-BP) or internal at one end and external at the other (BP-HP). In the construction and interior of buildings, imported stainless steel bends are more often used — they have a more beautiful appearance (all clarified) and a variety of surface treatments. The most common surface is matte, but also use ground and mirror (polished) surfaces. Such bends with a special surface treatment are wrapped in a film to preserve during transportation or installation.
