Pressure–Temperature Introduction

This section explains the allowed pressure range (about 0 MPa to 1.5–2.0 MPa) for temperatures between -40°C and 120°C. It appears in technical data for valves, fittings, or other fluid systems. It defines safe working boundaries for NINGHAO Machinery’s Customizable Double Ball Neoprene Rubber Expansion Joint for Vibration Absorption.

1. Temperature and Pressure Axes
   Temperatures span from -40°C to 120°C on the horizontal axis. Pressures range from near 0 MPa to 1.5–2.0 MPa on the vertical axis. This grid shows how pressure limits change with temperature shifts.

   
   

2. Gray Area (Safe Zone)
   The gray region indicates permissible operating pressure at each temperature. Stepping outside it can increase risk. This area helps users identify safe conditions for fluid flow or equipment performance.

   
   

3. Phase or Operational Boundaries
   Some charts show fluid phase changes within this region. These transitions guide decisions about pressure settings. Exceeding safe lines can lead to material or seal failure.
