About This Product

Buttweld Flexolet

A Buttweld Flexolet is a branch connection fitting used to create an outlet from a main pipe in a piping system. Its butt-weld connection is intended to integrate the branch fitting with the piping arrangement through welding. The appropriate fitting configuration depends on the main pipe dimensions, branch size, material, wall thickness, and applicable design requirements.

GS MetalFit’s product catalogue covers a broad range of branch connection fittings and material options, including stainless steel, carbon steel, alloy steel, duplex and super duplex grades, nickel alloys, and copper-based alloys. The supplied source also references forged construction and special-material options, including Nickel 200, Inconel 625, Monel 400, Hastelloy C276, Alloy 20, SMO 254, and Titanium Grade 2.

The source describes outlet fittings in butt-weld, socket-weld, and threaded configurations across its broader olet range. These connection types are distinct product configurations and should be confirmed individually when enquiring about a Buttweld Flexolet.
