BUTT-WELD FITTINGS

This kind of components perform various functions such as directing fluids (elbows), change of pressure (reductions), derivation (tees), to cover, protect or seal (caps) and flanged coupling (stub ends). These are joined by butt welding and have the characteristic beveled ends, through it the welding gets a good penetration and then best mechanical resistance.

Butt weld fittings are manufactured under the guidelines of ASTM (American Society for Testing and Materials) and dimensions according to ASME B16.9 (grade WP) and MSS-SP43 (CR grade).

CONCENTRIC REDUCER


TECHTUBE© concentric reducers are made of stainless steel based on ASTM A403 standard. These are components that cause a change in the fluid pressure through the reduction of the diameter on a pipe line. They have a common central line connected with different pipe diameter

TYPE “C” STUB-END


Type C’s are fittings with straight body and flap. It is manufactured by a cold Deep drawing process. It is used in flanged connections, where the straight body enters on the central hole of a Lap Joint flange and then it is butt welded to a pipe.
