Butt Weld Pipe Fitting Up Station
Oct 06, 2016

Pipe fitting is the occupation of installing or repairing piping or tubing systems that convey liquid, gas, and occasionally solid materials. This work involves selecting and preparing pipe or tubing, joining it together by various means, and the location and repair of leaks.  They work in such diverse fields as oil refineries, paper mills, nuclear power plants, and manufacturing plants. They install medical gas lines in hospitals, and high-purity process piping for semiconductor, biotechnology, and pharmaceutical manufacturing.

butt weld pipe fitting is designed to be welded on site at its end(s) to connect pipe(s) together and allow change in direction or pipe diameter, or branching or ending. This fitting then becomes part of a system for transporting fluids (oil, gas, steam, chemicals …) in a safe and efficient manner, over short or long distances. Other types of fittings can be threaded or socket welded.

Flanges connect pipes by bolting them together, whereas butt weld fittings connect pipes by welding them together. Depending on size, butt weld fittings require 10% to 75% less material than a flanged connection, which means lower material cost and lower weight. Welded construction permits greater freedom in designing a layout; this system uses less space, is more compact, and has greater strength. Butt weld fittings provide optimum flow characteristics, without pockets or sharp corners, creating less frictional resistance, no pressure loss, less turbulence, …

Fittings are used wherever liquids, gases, chemicals and other fluids are created, processed, transported, or used. Range of industries is very wide, as shown below:

·         Energy related.

·         Food and beverage production.

·         Semiconductor manufacturing:

·          Pulp and paper production.

·         Production of construction materials and plastics.
