250 degree Fahrenheit intermittently
and from full vacuum to 15 psi. All
joints shall be made using couplings of stainless steel with Teflon liners,
which have leak-free deflection characteristics of 4 degrees.
Odd lengths shall be fabricated by field cutting and joining with
stainless steel, bead to plain end coupling with Teflon liner.
The stainless steel shell will enclose the liner at each end of the
coupling. ABOVE GROUND: Pipes passing through walls and floors shall be fitted with pipe sleeves a minimum of 2” greater diameter than the pipe O.D. Caulk the annular space between the pipe and sleeve with approved sealing material. Piping shall not be installed in direct contact with concrete. All fabrication and installations to be in accordance with manufacturer’s installation manual. UNDER GROUND: Buried pipe shall be encased in 1.5 lbs. Per cubic foot density expanded polystyrene and the fittings shall be protected against scratching. Installation to be in accordance with manufacturer’s installation manual.
