PVC (MO) stands for Molecular Oriented Poly(Vinyl Chloride). The process of molecular orientation has long been used to strengthen many materials. Ultra-Blue is manufactured by a process that reorients the molecules of conventionally extruded PVC pipe. The pipe, approximately half the diameter and twice the wall thickness of the finished Ultra-Blue product, is placed inside a mold sized to the proper outside diameter of the finished product. The temperature of the pipe is raised to the appropriate level for expansion and internal pressure is applied. This internal pressure causes the pipe to uniformly expand to the inside dimensions of the mold. The mold is designed so that during the process, the bell and gasket groove are also formed, producing a high quality bell. During the pipe expansion process, the molecular orientation is changed and the physical properties of the finished pipe product are established.

Improvements in design and physical properties include:

• Ultra Performance

  Meets or exceeds all the performance requirements of ASTM D2241, SDR 21, 200 psi pressure rated pipe

• Ultra Hoop Strength

  Molecular orientation through the manufacturing process of extrusion and expansion greatly enhance the material's hydrostatic design strength

• Ultra Endurance in Cyclic Applications

  Has four times the cyclic fatigue strength compared to conventional PVC of the same pressure rating

• Ultra Impact Strength

  Superior cold weather impact resistance

• Ultra Tough

  Resists logitudinal cracking

• Ultra Tight Joint

  Proven Forsheda style gasket system

• Ultra Light Weight

  45% lighter than SDR 21

• Ultra Flow Capacity

  Larger inside diameter results in 9% greater flow capacity
