液压试验机器

1. Functions Usage: Plastic Pipes Hydrostatic Pressure Testing Machine is mainly used to determine of the resistance of thermoplastics pipes to constant internal water pressure at constant temperature. It is mainly used in testing the short-time hydraulic failure and resistance to constant internal pressure of the plastic pipes for the transport of fluids.It is the pipe manufacture’s necessary equipment. Basic Principle: According to the different temperature and pressure, input different parameters into the industry controlling machine. The high pressure pump produces the high pressure liquid. By the pressure controlling system, high-pressure tube transports medium thermostat inside sample, doing the pump long-term’s hydrostatic experiments. 2. standards-compliant 2.1 ISO 1167-1-2006 Thermoplastics pipes, fittings and assemblies for the conveyance of fluids - Determination of the resistance to internal pressure - Part 1: General method 2.2 ISO 1167-2-2006 Thermoplastics pipes, fittings and assemblies for the conveyance of fluids - Determination of the resistance to internal pressure - Part 2: Preparation of pipe test pieces 2.3 DIN EN ISO 1167-3-2008 Thermoplastics pipes, fittings and assemblies for the conveyance of fluids - Determination of the resistance to internal pressure - Part 3: Preparation of components 2.4 ASTM D1598 Standard Test Method for Time-to-Failure of Plastic Pipe Under Constant Internal Pressure 2.5 ASTM D1599 Standard Test Method for Resistance to Short-Time Hydraulic Failure Pressure of Plastic Pipe, Tubing, and Fittings 2.6 GB/T6111—2003 Liquid transportation use thermo plasticity plastic pipe withstand voltage testing way 2.7 GB/T15560—1995 Standard test method for short-time hydraulic failureAnd resistance to constant internal pressure of the plastics pipes for the transport of fluids 3.
