Buttweld Fittings

A steel buttweld fitting is defined as a part, used in piping system to change the direction or function, which is mechanically joined to the system.

we are suppliy steel buttweld fittings in all types of material like stainless steel buttweld fittings, carbon steel buttweld fittings, Alloy steel buttweld fittings, duplex steel buttweld fittings, Monel, Nickel, Inconel, Hastalloy, Titanium, Tantalum etc.

Probably the simplest way to achieve this end would be to bend the pipe in the direction required, but this process will stretch and thin the outer wall whilst thickening and wrinkling the inner wall. This result in flow resistance and accelerated wall erosion.

A second method sometimes used is a mitred joint, where pipes are cut to the correct angle and welded together to achieve the desired change. Whilst the cross-section area and wall thickness are maintained a great deal of efficiency is lost due to friction and turbulence resulting from the severe changes in direction; for example a single mitred bend offers about six times the resistance of a swept elbow.

For these reasons swept fittings are preferred on most pipe systems, particularly where internal pressure, flow and corrosion are major consideration.

Types And Applications :
A piping systems using butt Welding fittings has many inherent advantages over other forms.

• Welding a fitting to the pipe means that it is permanently leak proof.
• The continuous metal structure formed between pipes and fitting adds strength to the systems.
• Smooth inner surface and gradual directional changes reduce pressure losses, turbulence and minimizes the action of corrosion and erosion.
• A welded system utilizes a minimum of space.
