Tube-to-Tubesheet Welding

TDM specializes in tube-to-tubesheet welding. We have completed mock-ups for customers that require it.

Strength Welded Joints

Recommended for high stress tube-to-tubesheet joints
Recommended for certain process conditions
Often requires mock-ups for WPS/PQR approval
TDM has many types of mock-ups for strength welding including:
Alloy 20, C276, 2205, Monel 400, Nickel 200, AL6XN, 90/10 CuNi

Seal Welded Joints

Increased reliability
Reduced Maintenance Costs
Fewer Process Leaks
Common when clad tube sheets are used
