Specialist contractor to freeze the existing 6"main pipe work serving the redundant tanks and install 6" isolation valve using WRAS approved compression flange
If there is no compression flange

To accurately establish l-joist stiffness and strength, it was essential to maintain lateral stability of the I-joist compression flange
during each test.
The current load resistance factor design (LRFD) equations for I-joist lateral buckling assume that the compression flange acts as a column restrained in the direction of the web.
Increased I-joist spans have led to questions about the lateral stability of these structural framing materials in situations where continuous lateral bracing is not provided along the compression flange, e.
From experience, this is the usual case; if an I-joist is devised such that bending failures are mostly in the compression flange
or in the web, further study will be required.
Technical limitations on suction blow molding, however, are that it doesn't readily allow either compression flanges
on parts or metal inserts, the way x-y-z and robotic tooling approaches do.
