Butt Weld Fitting

Butt-weld Fittings are used in a piping system to change direction or function of media, which is mechanically welded to the system completely. A welded joint actually becomes part of the pipe, minimizing leak potential. This welding provides greater margins of safety, especially under conditions of high internal pressures. 

ZAFFERTEC S.L. is able to supply a wide range of butt-weld fittings in all sizes and materials. Our Fittings are produced in our equipped workshops in Italy and Spain by the most famous manufacturers in which the product lines in fitting processing work with the highest standards in quality and reliability under strict quality control system. 

Reducers in both Concentric and Eccentric types, Tees in both Equal and Reducing types, Elbows in both 45° and 90° types, Caps and Bends are major part of the comprehensive range of butt-weld fittings carried by ZAFFERTEC S.L. 

Carbon Steel and Stainless Steel materials are in our scope of supply. Seamless and Welded Fitting types are both available from our material stocks and operating production lines. These fittings conform to relevant material and dimensional standards according to ANSI norms and can be supplied with high quality European raw materials. EN 10204/3.1 certificates are attached to all materials.

Sometimes Butt-weld fittings should be produced under non-standard drawing or requirement, especially in extra-long radius or large size of Bends or Tees, according to clients inquiries. We are specialized on tailor made non-standard fittings that should be fixed to your piping system with high performance operation. Sometimes mechanical or chemical corrosion or high pressure of flow or extreme temperature can be important. In this case, our designs will be the best solution for reliable and safe operation.
