Customizable Hydrostatic Test Line For Tube Mill Steel Pipes

The Water Pressure Test Tube Mill Line is a critical quality inspection system tailored for steel pipe manufacturing, designed to conduct hydrostatic pressure testing on finished steel pipes—ensuring they meet pressure-bearing standards and leak-proof requirements for industrial applications (e.g., oil/gas pipelines, water supply pipes, pressure vessels). As an integral part of tube mill production lines, this system detects hidden defects (such as micro-cracks, weak welds) in pipes by applying controlled water pressure, helping manufacturers avoid safety hazards and comply with international quality certifications (e.g., API, ISO).

Junxi Machinery, a leading manufacturer of steel pipe manufacturing equipment, offers this specialized Water Pressure Test Line under the Tendi product series—backed by years of industry expertise and a team of skilled professionals. We pride ourselves on providing customizable solutions: whether you produce small-diameter pipes (Φ50mm) or large-diameter pipes (Φ610mm), we can tailor the test line to match your pipe specifications, production capacity, and on-site space. Our commitment to high standards ensures every system undergoes rigorous testing before delivery, guaranteeing reliability, accuracy, and long-term performance for your steel pipe production.

Below are the comprehensive technical specifications of the Tendi series Water Pressure Test Tube Mill Line, covering models for different pipe diameter ranges, pressure capacities, and spatial requirements:

• Precise Pressure Control: Equipped with high-precision pressure sensors and a hydraulic control system, the line maintains stable test pressure (up to 70 Mpa for large-diameter models) with minimal fluctuation, ensuring accurate defect detection.
• Adjustable Pipe Compatibility: Each model supports a specific range of pipe diameters and lengths (e.g., TD-600 handles Φ219~Φ610mm pipes up to 12m long), with customizable clamping fixtures to fit non-standard pipe sizes.
• Automated Testing Process: From pipe loading, sealing, water filling, pressure application, to pressure holding and unloading—most steps are automated, reducing manual intervention and improving testing efficiency (suitable for high-volume tube mill lines).
• Defect Alarm & Data Recording: The system automatically alerts operators if pressure drops (indicating leaks) and records test data (pressure, duration, pipe ID) for traceability—meeting quality audit requirements.

1. Pipe Loading: The steel pipe to be tested is conveyed to the test station via a roller conveyor, aligned, and clamped by sealing heads at both ends (to prevent water leakage during testing).
2. Water Filling: The pipe is filled with clean water (or anti-corrosive fluid for stainless steel pipes) to expel air—ensuring uniform pressure distribution inside the pipe.
3. Pressure Application: A high-pressure pump (powered by the system’s motor) increases the water pressure inside the pipe to the preset test value (e.g., 50 Mpa for TD-100), and the pressure is held for a specified duration (adjustable based on pipe standards).
4. Leak Detection: Pressure sensors monitor the internal pressure in real-time. If no pressure drop is detected, the pipe passes the test; if leaks occur, the system triggers an alarm and marks the pipe for rework or rejection.
5. Unloading & Drainage: After testing, the pressure is released, water is drained from the pipe, and the pipe is conveyed to the next station (packaging or storage) if it passes.

• Customization: We tailor the test line to your tube mill’s output, pipe specifications, and factory layout—ensuring seamless integration with your existing production process.
• Expertise: Our team of engineers has years of experience in steel pipe equipment design, providing professional guidance on test standards (e.g., API 5L for oil pipes) and system optimization.
• Quality Assurance: All components (pumps, sensors, seals) are sourced from reliable suppliers, and every system undergoes a 72-hour continuous operation test before delivery to ensure performance stability.

• Installation & Training: We send technicians to your site for system installation, commissioning, and operator training—ensuring your team masters daily operation and basic maintenance.
• Spare Parts Supply: We maintain a stock of key spare parts (sealing rings, pressure sensors) for quick delivery, minimizing downtime.
• Technical Consultation: Our after-sales team provides lifelong technical support via phone, email, or video call—responding to your inquiries within 24 hours.

This Water Pressure Test Tube Mill Line is essential for steel pipe manufacturers in industries such as:

• Oil & Gas: Testing seamless or ERW pipes for pipeline transportation (ensuring resistance to high pressure and corrosion).
• Water Supply & Drainage: Inspecting large-diameter steel pipes for municipal water supply or industrial wastewater discharge (leak-proof requirement).
• Pressure Vessels: Testing small-diameter precision pipes used in boilers, chemical reactors, or automotive hydraulic systems (high pressure-bearing standards).

Whether you run a small tube mill or a large-scale steel pipe production plant, our Water Pressure Test Line provides the quality assurance you need to compete in the global market. We welcome opportunities to discuss your specific needs and explore cooperation.
