[MW:3061] Re: piping and pipleine spacing

Dear Daniel ,
 
If you are looking for spacing between the pipe and the ground , it is stated in the API 1104 for p/l ,
 
If you are looking for spacing between 2 welds  usually it is 3  times diameter , or as per client specification
 
Usually this is defined as if the lenght is less will cause distorsion if the pup piec is very small in lenght and at the same should see their is a min spacing of 2 " between the HAZ of the 2 welds , in case u need to come to a smaller lenght .
 
Thanks
