JCM 230/231 Stainless Steel Stiffeners for HDPE Pipe For applications on High Density Polyethylene Pipe, using mechanical bolt on fittings to join or connection systems, JCM recommends the use of the JCM 230/231 Stainless Steel Pipe Stiffeners. JCM 230/231 Stiffeners provide:
• Corrosion Resistance • Rigid Reinforcement of Pipe Wall for Pipe Connections • Accurate Pipe I.D. Sizing maintains proper Outside Diameter • 1/8” Tapered Insert End provides for Easy Installation • 90° 1/8” Flared End Secures Stiffener to End of Pipe • Positive Reinforcement without interference
JCM HDPE Pipe Stiffeners are designed to support the interior wall of HDPE for critical pipe joining applications. Recommended for all pipe end connections utilizing mechanical bolt-on fittings, the JCM Pipe Stiffeners support the pipe’s end and controls the “necking down” reaction to the pressure applied during normal installation of fittings used in pipe joining applications. The JCM HDPE Pipe Stiffeners are formed of stainless steel, 304 or 316 material, to the actual inside pipe diameter provided by the customer. This accurate formation provides for ease of installation and maintains the proper outside diameter for a successful, trouble free application that provides long-term service. JCM Pipe Stiffeners are available for Steel Size and Ductile Iron Size HDPE in SDR11,13.5, 17, 21, 26, 32.5 JCM Pipe Stiffeners Material Specifications: ASTM A240 - TP 304 Stainless Steel or 316 Stainless Steel
