The thermo water baths for pressure testing manufactured by Bayerteq provide state-of-the-art conditioning and immersion testing for thermoplastic pipes, tubes, and fittings. Engineered in strict accordance with international standards including ISO 1167, ASTM D1598, and ASTM D1599, these premium stainless steel test baths ensure unparalleled thermal stability, user safety, and operational longevity for pipe extrusion facilities and quality control laboratories.
Hydrostatic durability evaluation requires pipe specimens to be immersed under continuous internal water pressure at strictly regulated temperatures for extended durations up to thousands of hours. Bayerteq thermo water baths for pressure testing guarantee uniform heat distribution throughout the entire liquid volume via high-efficiency circulation pumps and submerged heating elements, safeguarding the structural integrity and precision of every test.
Thermo Water Baths for Pressure Testing Configurations & Features
To accommodate diverse laboratory layouts and pipe specimen diameters from small microducts up to large-diameter sewage and gas pipes, Bayerteq delivers specialized model configurations:
- SL Series (Single Lid, up to 2500 mm length): Compact and mid-sized thermo water baths featuring a single pneumatically operated lid with a front-mounted control switch for fast, ergonomic specimen loading.
- SL Series (Single Lid, 2500 mm to 5000 mm length): Extended single-lid bath configurations engineered for long pipe sample spans and high-capacity batch hydrostatic testing.
- FL Series (Foldable Lid): Heavy-duty large-volume baths equipped with a segmented foldable lid that allows partial opening, minimizing thermal loss while loading large pipe assemblies.
- Integrated Safety & Energy Efficiency: Double-layer thermal insulation reduces electrical power consumption by more than 70%. Even when operating at maximum water temperatures of 95 °C, the outer lid surface remains safely at ambient room temperature. An independent over-temperature protection circuit and dry-run safety sensors prevent heater failure under all conditions.
Every system includes a dedicated temperature control cabinet, vapor containment system, quick-disconnect specimen couplings, and maintenance access panels that allow pump or heater service while the bath remains filled with water.

Advanced Engineering & Operational Features
AISI 304 / 316 Stainless Steel Tank
Constructed entirely from premium industrial stainless steel with seamless interior welds, providing maximum corrosion resistance and longevity under continuous 24/7 exposure to hot water.
Pneumatic Assisted Lid Mechanism
Lids open and close smoothly via pneumatic cylinders controlled by front-panel switches. Operators can access the tank effortlessly without manual lifting or safety hazard.
Superior Double Thermal Insulation
High-efficiency thermal barrier minimizes heat loss, cutting energy consumption by over 70%. Even when bath water boils at 95 °C, the outer lid remains at room temperature to eliminate burn risks.
Dual-Circuit Over-Temperature Protection
A separate, independent safety circuit monitors heating element temperatures and triggers immediate shutdown in the event of primary sensor failure or liquid starvation.
Service Without Draining Water
Unique modular engineering allows technical staff to remove outer panels and service circulation pumps, heating elements, and sensors while the bath is filled with water, eliminating costly downtime.
Vapor & Steam Containment System
Integrated steam collection channels trap vapors inside the tank, preventing steam accumulation in the laboratory environment and maintaining optimal indoor air quality.
System Integration & Optional Accessories
1. Pressure Test Cabinets (HPM Series)
Directly interfaces with Bayerteq HPM pressure cabinets for independent multi-station pressure control up to 100 bar, 160 bar, or 200 bar with millibar precision.
2. Water Chiller Units
Optional closed-loop industrial chillers connect directly to the thermo bath to maintain test temperatures below ambient (e.g. 20 °C or 10 °C) during warm summer periods.
3. Quick-Coupling Manifolds
Custom stainless steel distribution manifolds with flexible high-pressure hoses and drip-free quick couplings to connect 5 to 50+ test specimens simultaneously.
4. Bayerteq BT Software Integration
Automated software integration for synchronizing bath temperature logs with specimen pressure curves, delivering complete test certificates and ISO 17025 compliant records.
