Stainless collars
Collar (side washer, flanging) is a type of fittings for connecting pipeline elements using free flanges. It is a ring whose diameter is equal to the diameter of the pipe, with a side, the so-called collar. The end of the part is welded to the end of the pipe, forming a sealed seam. The loose flanges put on the pipe are tightened with bolts or studs using a seal. The resulting connection is strong, reliable, easy to disassemble and assemble for repair and maintenance. It is used in pipelines and installation of containers to connect them to the pipe.
ALFA-STAR company supplies collars made of AISI 304 stainless steel according to DIN and ISO standards. Products made of this material can withstand significant mechanical loads, pressure drops, high humidity. They operate in the temperature range -70°C - +600°C in aggressive environments without loss of operational properties during the entire service life, which is tens of years. Environmental cleanliness and anti-corrosion properties of stainless steel remove restrictions on the scope of application of parts made of it. Good weldability of AISI 304 steel ensures tightness of the seam at the junction of the collar and pipe. Welded joints with stainless components are used in pipelines operating in abrasive and aggressive environments, where it is necessary to eliminate the risk of leaks.
