Why is a gap ring used on a socket weld?

Gap-A-Let rings help piping engineers determine the end-to-end length of the pipe without guessing. Constant, proper gap gives precise length whether in field run or fab shop assembly. Three easy steps to make proper 1/16″ minimum gap socket welds in seconds.

What is a Gap a Let?

Gap-A-Let® is a split ring that is engineered and designed to give you a pre-measured 1/16″ minimum gap for socket welds. Made from a certified stainless steel, Gap-A-Let® resists corrosion from chemicals, radioactive materials, and water. Socket welds that once took 15 minutes or more to fit-up now take just seconds.

Can socket welds be Radiographed?

In my experience socket welds can be radiographed. The radiograph only tells you whether there is appropriate root gap, not much on the quality of the weld.

How do you determine root gap in welding?

The plate edges must be tightly butted (1/32-in. maximum gap) as with the square butt joint. When the welding composition is retained by a support below the joint, slightly greater root gaps are permissible; if the root gap exceeds 1/16- in., submerged arc welding flux should be tamped into the gap ahead of the weld.

What is the difference between Weldolet and Threadolet?

The mainly differences are the connection surface, weldolet ends in plain or beveled to weld on the the branch pipe, sockolet ends in socket type that to insert branch pipe. Threadolet is insert branch pipe and with screw connection. Weldolet: Compatible with higher pressure and simple connection, cost lower.

What is meant by root gap in welding?

Root gap – the minimum distance between the ends of the elements to be welded which is measured during the assembly of the butt joint for welding.

Which is stronger socket weld or butt weld?

Socket weld (the fillet weld) resists around 1/2 the strength of butt welding. Butt weld keeps better strength, good for high pressure or high temperature pipelines. So it is used when a welded joint with strength not lower than that of the base metal itself is needed.
