Weldneck flanges
Weldneck flanges have drilled wall thickness which is of equally same dimension existing for matching pipe. Bore will be larger if the pipe is lighter and opposite will be true if pipe is heavier and the bore will be small.
Erosion as well as turbulence is significantly reduced in pipeline as bores of flange & pipe match. Due to these reasons weldneck flanges are chosen for critical applications where high pressure and hot-cold temperatures are prevalent. The different kinds of weldneck flanges available are:
