Hot Dip Galvanized (ASTM-A153) or Electrodepositied Galvanized (ASTM-B633) Carbon Steel Fitting Products Compliance and Product Warning
Penn Machine manufactures pressure fittings in SA/A105, SA/A106, SA/234, SA/333, SA/A350 and SA/420 which are galvanized with Zinc and conform to the specifications of ASTM-B633 and ASTM-A153 respectively. The melting point of elemental Zinc is approximately 780 Degrees F [415 C]. Therefore, application of Zinc Coated piping products should be limited to temperatures less than 390 Dergees F [210 C]. Use of Galvanized coated piping products at temperatures above approximately one-half the melting point (Fahrenheit or Celsius) of the galvanized coating is not recommended unless consideration is given to the potential for liquid and solid metal embrittlement, or both.
Lead Free Galvanized Products from Penn Machine
Penn Machine Galvanized products are Hot Dip Galvanized per ASTM-A153 or Electroplated Deposited Galvanized per ASTM-B633. These products are supplied to our users as lead free meaning containing less than 8 % lead as stated in the “Safe Water Drinking Act of 1998”. These products are classified as in line piping to the water system and are not required to meet NSF Standard 61 Section 9 under the Safe Water Drinking Act of 1998.
