[MW:20186] Cut -Out Of Joint's

I hv'nt seen such requirement or restriction.

any way as part of good workmanship maximum 2 times is suitable to maintain HAZ property or else cut up to HAZ each side to facilitate new HAZ.

Fitting joints more times CRW very difficult,especially elbow,TEE.

Number of cut and re weld depend whether it is SS or CS materials.

For SS,DSS,SDSS special care should be taken avoid re repair to control ferrite number,corrosion property.

Hope this help.

Regards
Mohd.
