Product Description

Hydrostatic Tester Machine

✅ What Is a Hydrostatic Tester Machine?

A hydrostatic tester machine is specialized equipment used to verify the strength, safety, and leakage resistance of pipes, tubes, cylinders, pressure vessels, and valves. The machine works by filling the component with water (or other non-compressible liquid) and applying pressure higher than its normal operating level. This ensures compliance with ASME, ASTM, ISO, and API standards for safety and quality.

✅ Main Functions & Applications

Leak Detection – Identify cracks, weld defects, or weak joints.
Strength Verification – Confirm pressure endurance of industrial products.
Quality Control – Essential for manufacturers before product delivery.
Regulatory Compliance – Meet international codes and safety standards.
Industry Applications – Oil & gas pipelines, boilers, heat exchangers, water supply systems, LPG cylinders, and automotive components.

✅ Technical Specifications

Parameter	Value / Description
Max Test Pressure	10MPa-70MPa
Pump Type	Electric or pneumatic hydrostatic pump
Test Medium	Clean water or compatible fluid
Accuracy	±0.25% FS (analog or digital gauges)
Holding Time	10 – 60 minutes (adjustable)

✅ How Hydrostatic Testing Works

Preparation – Fill the specimen with water and remove trapped air.
Pressurization – Apply pressure gradually using the test pump.
Pressure Holding – Maintain test pressure for 10–60 minutes.
Inspection – Monitor for leaks, pressure drops, or deformation.
Certification – Record test data and issue pass/fail documentation.

✅ Accessories & Optional Parts

A complete hydrostatic tester machine includes the following accessories for safe and efficient operation:

Accessory	Description
Hydrostatic Test Pump	Core component generating high water pressure; available in electric or air-driven models.
Pressure Gauges / Digital Sensors	For real-time monitoring and recording of pressure values.

Water Reservoir / Tank	Stores clean water or compatible test fluid.
High-Pressure Hoses & Fittings	Connects the specimen securely with leak-proof coupling.
Sealing Fixtures / End Caps	Provides tight sealing for pipes, valves, and cylinders.
Air Venting Device	Removes air pockets for accurate results.
Data Acquisition System	Optional logging and reporting system.
Control Panel (PLC/Manual)	Controls pressurization, holding, and decompression steps.
Safety Shields / Test Chamber	Protects operators during high-pressure tests.

Industrial Hydrostatic Pressure Testing Equipment

✅ Frequently Asked Questions (FAQ)

Q1: Why is water preferred over air for testing?
👉 Water is incompressible, making it safer and more reliable than compressed gas.

Q2: What pressure is typically applied?
👉 Normally 1.3 to 1.5 times the design pressure of the tested equipment.

Q3: Can the hydrostatic tester be automated?
👉 Yes, modern machines use PLC or touchscreen control systems for automation and digital data logging.

Q4: Which industries use hydrostatic testers?
👉 Oil & gas, chemical plants, power generation, water supply, boiler and heat exchanger manufacturing, and cylinder testing facilities.

Q5: How often should vessels be tested?
👉 Testing intervals depend on regulations (ASME, DOT, ISO) and usually range from 1 to 5 years.

Pipe Hydro Tester Machine FAQs

What is a pipe hydro tester used for?

It’s used to test steel pipes for internal pressure strength and leaks by filling them with high-pressure water and monitoring their performance under pressure.

What is the typical test pressure?

Test pressures range from 10 MPa to 70 MPa, depending on pipe diameter, thickness, and industry standards.

What medium is used for testing?

Clean water is standard. Some systems may use water mixed with anti-rust agents.

How long does a test take per pipe?

A full test (clamping, pressurizing, holding, draining, and unclamping) usually takes 30 to 90 seconds per pipe, depending on size and automation level.

How is pressure monitored and controlled?

Via pressure sensors and digital displays With PLC control systems, pressure is auto-adjusted and monitored in real time
