Compact-Sized Auto-Water-Level Electric Thermal Bath for Pipelines
Designed for pipeline testing facilities and commercial procurement clients, this compact auto-water-level electric thermal bath ensures uninterrupted, stable temperature conditions for hydrostatic testing. It operates from 15°C to 95°C with ±0.5°C accuracy, automatically maintains water levels with minimal temperature fluctuation, and cuts energy use by 70% via high-performance insulation per ISO 1167 requirements.
Product Overview: Electric Thermal Bath for Pipe Testing
GT-TEST compact-sized auto-water-level electric thermal bath (Model GT-TANK-A) provides controlled constant-temperature water immersion for hydrostatic pressure testing of thermoplastic pipes. Designed for pipeline testing facilities and commercial procurement clients, the bath maintains a temperature range of 15°C to 95°C with a temperature accuracy of ±0.5°C and a temperature resolution of ±0.1°C. An automatic water-level control system replenishes water when the level drops below the preset value, introducing water in a manner that limits temperature fluctuation to less than 0.2°C. High-performance thermal insulation reduces power consumption by more than 70% compared with non-insulated equivalents, and the outer lid remains near ambient temperature even when the bath operates at 95°C.
Key Design Features of Auto-Water-Level Thermal Baths
Automatic Water-Level Control with Minimal Temperature Fluctuation
When the water level falls below the programmed threshold, the system automatically introduces makeup water. The inlet design and circulation system work together to limit the resulting temperature fluctuation to less than 0.2°C, preventing test-condition deviations during long-duration pressure tests.
Circulation System for Uniform Temperature Distribution
A built-in circulation pump ensures that water temperature remains uniform throughout the bath volume. This is relevant for multi-station test setups where specimens at different positions within the tank must experience identical thermal conditions.
High-Performance Thermal Insulation
The basic container is insulated to reduce heat loss. At a water temperature of 95°C, the outer surface remains near ambient temperature, improving operator safety and reducing energy consumption by more than 70% relative to uninsulated tanks of equivalent volume.
Structural Bracing Frame
A braced structural frame provides rigidity and resistance to deformation under the weight of large-diameter pipe specimens and water load. Quick-release couplings and an ergonomically arranged manifold simplify specimen connection and disconnection.

Applicable Standards for Pipeline Thermal Baths
ISO 1167 Temperature Compliance
ISO 1167 requires testing at specified constant temperatures. The GT-TANK-A bath maintains the required thermal environment, and the circulation system ensures temperature uniformity across all immersed specimens.
ASTM D 1598 and ASTM D 1599
Both standards specify test conditions that include controlled water temperature. The bath's temperature accuracy of ±0.5°C and resolution of ±0.1°C support compliance with these test methods.
Industrial Applications of Compact Electric Thermal Baths
These thermal baths are used by pipe manufacturers, independent testing laboratories, and quality-assurance departments for long-term hydrostatic pressure testing and short-term burst testing of PE, PEX, PVC, PP, and PB pipes. The scalable station count (1 to 50) allows the same bath design to serve low-volume R&D laboratories and high-volume production testing lines. Various bath sizes and lid configurations are available to match specific pipe diameters and test layouts.
FAQ
What is the temperature range and accuracy?
The bath operates from 15°C to 95°C with a temperature accuracy of ±0.5°C and a resolution of ±0.1°C.
How does the automatic water-level control work?
When the water level drops below the preset threshold, the system automatically adds makeup water. The refill process is designed to limit temperature fluctuation to less than 0.2°C.
How many test stations can the bath accommodate?
The bath supports 1 to 50 test stations, configured to client requirements. The internal dimensions are customized based on the pipe diameter being tested.
What energy savings does the insulation provide?
The high-performance insulation reduces power consumption by more than 70% compared with an equivalent uninsulated bath, based on internal comparative testing at 95°C operating temperature.
Are different bath sizes available?
Yes, various internal dimensions and lid systems are available. Clients should provide the maximum pipe diameter and number of stations to receive a tailored configuration and quotation.
