Large Diameter Pipe
Figure 10
A lateral Tee sticking out of the pipe line is a common occurrence in the field.
As shown in Fig.10, one machine has to be retracted to let the lateral tee pass. Fig. 11 shows how we tackle this problem.
As can be seen in above three machine setup (Fig.10), 4 tracks are engaged and two are retracted, i.e. six tracks are totally needed.
And again one of our machines is good for four conventional ones, that is three machines for above job (Fig.10) and one 4-track machine for small pipe.

We admit that our design might be somewhat costlier than one of the present machines, but certainly cheaper than two of today’s designs, not to mention four machines we are replacing.
