C215-88: AWWA Standard for Extruded Polyolefin Coatings for the Exterior of Steel Water Pipelines (PDF)

This standard covers two types of extrusion, crosshead and side, and three types of applications, as follows: Type A, crosshead-die extrusion, consists of an adhesive and an extruded polyolefin sheath; this system is limited to pipe diameters 1/2-36 in. (13-914 mm). Type B, side extrusion, consists of an extruded adhesive and an extruded polyolefin sheath; this system is limited to pipe diameters 2-120 in. (51-3048 mm). Type C, tape and side extrusion, consists of a primer/inner-layer tape and an extruded polyolefin sheath for spiral and longitudinal welded pipe; this system is limited to pipe diameters 4-120 in. (102-3048 mm). The history of the standard, metrication, and information regarding use of this standard are covered in the foreword. Section 1 discusses scope, definitions, references, affidavit of compliance, equipment, and materials and workmanship. Section 2 discusses coating system including description and requirements for coating materials. Section 3 discusses coating application including pipe preparation, coating application (Type A), coating application (Type B and Type C), coated-pipe test, coating repair, and coating of field joints. Section 4 discusses inspection, testing and rejection. Section 5 discusses handling and storage, field procedures, and packaging and marking. This is the First Edition of AWWA C215 for plant-applied extruded polyolefin coatings for the exterior of steel water pipe.
