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:

• Non-corroding
  
  
• Ductile Iron Pipe O.D.

  No transition gaskets or special fittings required

• Larger I.D. than Ductile Iron and Conventional PVC
  Superior flow capacity
  Less head loss
  
  
• Lighter weight than Ductile Iron and Conventional PVC
  43% lighter than C900 DR18
  Safer and easier to handle
  Lower installed cost
  More footage installed per day
  
  
• Higher Impact Strength
  4 times regular PVC
  No linings to crack
  
  
• Greater Cyclic and Hoop Strength
  
  
• Higher Design Stress
  
  
• Superior Notch Resistance
