This fourth case of pipe penetration is a preferred method. This is when the pipe is brought through the liner at a right angle (perpendicular). This usually occurs in the base of a pond with the pipe vertical, or on a side wall such as in a secondary containment wall.
This type of pipe penetration uses the mechanical compression of a pipe flange to clamp the liner in place. This requires no additional welding or liner work. The liner is simply placed over the pipe flange and holes cut for the the bolts. Once the unit is clamped together the liner is secure and leak free.
In cases where a technician cannot access the back of the liner to tighten the bolts, casting the pipe flange and bolts in concrete, or welding the bolts to the back of the flange will permit tightening.
