Description

Introduction to Hydrostatic Test Isothermal Tank

According to standard requirements, the internal pressure testing of pipes must be conducted under strictly controlled temperature conditions (typically 20°C for short-term tests and 80°C or 95°C for long-term creep tests). The Hydrostatic Test Isothermal Tank manufactured by Polymer Test provides a stable, fluctuation-free environment for immersing samples.

Structural Features and High Durability

Since this tank is in constant contact with hot water, corrosion resistance is our primary design priority:

Stainless Steel 304 Interior: We utilize non-magnetic, rust-proof Stainless Steel sheets for the inner liner, ensuring resistance against hot water and sediment buildup over years of operation.
Multi-Layer Insulation: Designed to prevent energy loss and keep the surrounding laboratory environment cool.
Custom Dimensions: We offer the capability to design and manufacture the tank in your desired length, width, and depth to match your production range (from small tanks for fittings to large basins for long PVC pipes).

Temperature Control and Circulation System

The water inside the tank must have an identical temperature at every point. The thermal features of the device include:

Circulation Pump: Provides continuous water circulation to eliminate thermal stratification, ensuring temperature uniformity with 0.1°C precision.
Flanged Elements: Uses powerful industrial heaters to rapidly reach the target test temperature.

Smart Connection to Pressure Unit

This tank is equipped with a Wireless Transmitter System that sends real-time water temperature data directly to the control panel of the Hydrostatic Pressure Tester without the need for cabling. This feature enhances laboratory safety by eliminating messy cables from the floor.

International Standards

The environmental conditions of this tank are calibrated to meet the requirements of:

Standard ISO 1167 (Thermoplastics pipes — Determination of resistance to internal pressure).
Standard ASTM D1598 (Time-to-Failure of Plastic Pipe Under Constant Internal Pressure).
