Branches, bosses and drain pockets welded to the pipes shall conform to the requirements of regulations 249 to 253. Branches shall not be welded to any main at an angle of less than 60°.

 


Reg. 362 B

External reinforcement

If the thickness of the main or branches of a single or multiple branch piece is less than that given by the equation 91-A external reinforcement shall be provided. Such reinforcement may take the form of multiple radial plates of ‘horse shoe’ form or the form of collars or other reinforcement, approved by the Chief Inspector, applied to or around the junction between the branch and the main”.



Reg. 362 C

Thickness where no external reinforcement is provided

Where more than one branch is attached to a pipe the opening of each branch shall be projected perpendicularly on the axis of the main and the distance between each pair of these projections measured. If the distance so measured between two branches is less than the sum of their bores, the two branches are deemed to affect each other; if this distance is equal to or greater than the sum of their bores, the two branches are deemed not to affect each other.
