7.0 SQUEEZE-OFFWARNING: Understand and follow all equipment manufacturer’s recommendationsand guidelines.PE gas pipe manufactured to ASTM D2513 is suitable for squeeze-off;however, squeeze-off practices are not limited to gas applications.Squeeze-off is applicable to PE 3408/3608/4710 pressure pipe.JM Eagle Municipal & Industrial Water or Sewer Pipe is suitable to propersqueeze-off procedures.Effective flow control is a basic requirement in piping systems. This is accomplishedwith the JM Eagle Municipal & Industrial Water or Sewer Pipe intwo ways. The primary method of flow control should be those installed systemvalves that are available. Secondly, squeeze-off using suitable equipmentcan be used to control flow or isolate a section of pipe. Also, squeezeoffis frequently used to control flow for emergency repairs or during certainpipeline or branch extension operations. Squeeze-off is applicable to sizesup to 16 inches and up to 100-psig internal pressures. Currently, there is nodemonstrated experience with larger sizes or higher pressures.This section describes equipment and explains proper procedures andprecautions for effectively and safely squeezing off JM Eagle Municipal& Industrial Water or Sewer Pipe for flow control. The pressure ratingof the pipe is retained if the recommended procedures and equipmentare used.7.1 ToolsSqueeze units suitable for use on JM Eagle Municipal & Industrial Wateror Sewer Pipe consist of steel bars and a mechanical or hydraulicmeans of forcing the bars together. These units are designed to squeezeJM Eagle Municipal & Industrial Water or Sewer Pipe until the inside surfacesmeet. This adequately controls flow although a leak tight seal is notalways obtained. A positive locking mechanism should be available.40 HDPE WATER/SEWER PIPING SYSTEM TECHNICAL & INSTALLATION GUIDE
