General Applications For Steel Buttweld Pipe Fittings

The buttweld pipe fitting is a simple yet effective way to connect two pieces of metal together. The process for applying this type requires you first to make sure both surfaces are clean, flat, and dry before welding them at high temperatures using special equipment that can withstand great amounts of temperature change without warping or melting away under pressure from gas like acetylene (which would cause an explosion).
The result? A strong connection with the minimal distortion will keep your project running smoothly longer than anything else!
Instead of cutting and soldering the pipes, a buttweld fitting is fitted with another pipe that has been ground down on one end. This allows for easier access to both ends while still providing adequate protection against corrosion because there’s no open spot in between them where moisture can gather easily 3/8 inch diameter x 24 inches long. 
The process starts by applying flux across the entire length before flawlessly welding together each pair using an Oxy-acetylene torch. When finished bonding all parts into the final shape carefully remove excess metal using round files or sandpaper until the polished smooth finish.

Butt-welded fittings are used in a wide range of industries to modify, separate, or stop the flow of fluids. These include waste treatment plants, oil processing, breweries, the chemical and petrochemical industries, cryogenic plants, paper and pulp production, gas treatment, and even nuclear power stations.

The choice of fittings varies according to the intended purpose.

‘Pipe Elbows’ are used to alter the pathway of a pipeline.

‘Pipe Reducers’ are needed to reduce or increase the size of the pipe bore size.

‘Pipe Tees’ or ‘Pipe Crosses’ are used to split the flow in the pipe multiple ways.

‘Pipe Caps’ are used if the pipeline needs to be closed off.
