Apr 26,2012·Using double-welded lap joints costs more than single-lap welds,but it is better from a corrosion and structural standpoint and allows pressure-testing to ensure that joints are water tight.Further,there are two welds to resist leakage,which are much like the difference between single-gasket and double-gasket joints.Assembling Pipes by Butt-Welding The Different Types of For example,in comparison with a 30° single angle bevel (grey zone plus red zone),a V bevel with a double angle of 30°/5° (grey zone) gives an economy of about 20% in terms of weld metal for a part 20mm (.787) thick.The potential savings in terms of bevel volume increase in proportion to the wall thickness of the pipe to be welded.Carbon Steel Weld Elbows - Pipe Fittings - FergusonShop for Carbon Steel Weld Elbows at Ferguson.Ferguson is the #1 US plumbing supply company and a top distributor of HVAC parts,waterworks supplies,and MRO products.
