【国外标准】 Standard Guide for Selection, Design, and Installation of Thermoplastic Water- Pressure Piping Systems

4.1 The requirements of this specification are intended to provide information to select, design and install thermoplastic, water-pressure piping systems. Materials covered in this specification are Poly(Vinyl Chloride) (PVC), Chlorinated Poly(Vinyl Chloride) (CPVC) and Polyethylene (PE) plastic pipe fittings.1.1 This guide is intended for use in the selection, design, and installation of thermoplastic water-pressure piping systems. For specific projects, a thorough review of this guide is recommended for the purpose of selecting specific materials, methods of joining, system design factor, and any special procedures deemed necessary to assure a satisfactory system.NOTE 1: Comprehensive information on the selection, design, joining, system design factors, installation and special products and piping systems for pressurized water and other specialized applications is available in the PPI Handbook of Polyethylene Pipe and from other domestic and International sources such as PE compound and product manufacturers and trade associations.1.2 It is recommended that governing codes and project specifications be consulted prior to the use of this guide. Nothing in this guide should be construed as recommending practices or systems at variance with governing codes and project specifications.1.3 The pipe, fittings, and joining materials shall meet the requirements of one or more of the following component product standards listed in 1.3.1 through 1.3.4 to the extent applicable. In 1.3.1, 1.3.2, and 1.3.4 the pipe standards followed by (a) are outside diameter-controlled pipes.1.3.1 For poly(vinyl chloride) (PVC) plastic piping components:  Title of Specification ASTMDesignationPoly(Vinyl Chloride) (PVC) Plastic Pipe, Schedules 40, 80 and 120 (a) D1785Poly(Vinyl Chloride) (PVC) Plastic Pipe (SDR-PR) (a) D2241Threaded Poly(Vinyl Chloride) (PVC) Plastic Pipe Fittings, Schedule 80 D2464Poly(Vinyl Chloride) (PVC) Plastic Pipe Fittings, Schedule 40 D2466Socket-Type Poly(Vinyl Chloride) (PVC) Plastic Pipe Fittings, Schedule 80 D2467Solvent Cements for Poly(Vinyl Chloride) (PVC) Plastic Pipe and Fittings D2564Bell-End Poly(Vinyl Chloride) (PVC) Pipe (a) D2672Poly(Vinyl Chloride) (PVC) Plastic Tubing (a) D2740Socket-Type Poly(Vinyl Chloride) (PVC) Plastic Line Couplings D3036Joints for Plastic Pressure Pipes Using Flexible Elastomeric Seals D3139Elastomeric Seals (Gaskets) for Joining Plastic Pipe F477PVC and ABS Injected Solvent Cemented Plastic Pipe Joints F5451.3.2 For Chlorinated Poly(Vinyl chloride) (CPVC) plastic piping components: Title of Specification ASTMDesignationChlorinated Poly(Vinyl chloride) (CPVC) Plastic Pipe, Schedules 40 and 80 (a) F441/F441MChlorinated Poly(Vinyl chloride) (CPVC) Plastic Pipe Fittings, Schedule 80 F439Solvent Cements for Chlorinated Poly(Vinyl chloride) (CPVC) Plastic Pipe and Fittings F4931.3.3 Standards for polyethylene (PE) plastic piping:  ASTM Standard DesignationStandard Specification for Polyethylene (PE) Plastic Pipe (SIDR-PR) Based on Controlled Inside Diameter D2239Standard Specification for Plastic Insert Fittings for Polyethylene (PE) Plastic Pipe D2609Standard Specification for Socket-Type Polyethylene Fittings for Outside Diameter-Controlled Polyethylene Pipe and Tubing D2683Standard Specification for Polyethylene (PE) Plastic Tubing D2737Standard Practice for Underground Installation of Thermoplastic Pressure Piping D2774Standard Specification for Butt Heat Fusion Polyethylene (PE) Plastic Fittings for Polyethylene (PE) Plastic Pipe and Tubing D3261Standard Specification for Polyethylene (PE) Plastic Pipe (DR-PR) Based on Controlled Outside Diameter D3035Standard Specification for Polyethylene (PE) Plastic Pipe (DR-PR) Based on Outside Diameter F714Standard Specification for Electrofusion Type Polyethylene Fittings for Outside Diameter Controlled Polyethylene and Crosslinked Polyethylene (PEX) Pipe and Tubing F1055Standard Specification for Socket Fusion Tools for Use in Socket Fusion Joining Polyethylene Pipe or Tubing and Fittings F1056Standard Practice for Electrofusion Joining Polyolefin Pipe and Fittings F1290Standard Specification for Deformed Polyethylene (PE) Liner F1533Standard Guide for Construction Procedures for Buried Plastic Pipe F1668Standard Practice for Field Leak Testing of Polyethylene (PE) and Crosslinked Polyethylene (PEX) Pressure Piping Systems Using Hydrostatic Pressure F2164Standard Specification for Fabricated Fittings of Butt-Fused Polyethylene (PE) F2206Standard Practice for Heat Fusion Joining of Polyethylene Pipe and Fittings F2620Standard Test Method for Laboratory Testing of Polyethylene (PE) Butt Fusion Joints using Tensile-Impact Method F2634Standard Practice for Field Leak Testing of Polyethylene (PE) Pressure Piping Systems Using Gaseous Testing Media Under Pressure (Pneumatic Leak Testing) F2786Standard Specification for Lap-Joint Type Flange Adapters for Polyethylene Pressure Pipe in Nominal Pipe Sizes ¾ in. to 65 in.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
