TG-28 Thermoplastic Pipe and Fitting Hydrostatic Burst Testing Machine

Product Introduction:

The TG-28 pipe static hydraulic burst test machine consists of a pressure station, a pressure control unit, and a computer software system. The primary function of the pressure station is to supply liquid pressure to the pressure control unit; its pressure output must exceed the maximum pressure required by the latter. This component employs a high‑flow, low‑noise, high‑pressure, maintenance‑free plunger pump that, when connected to an external pressurized softened water supply, can automatically replenish water, ensuring pressure stability and serving as a reliable pressure source. The pressure control unit comprises a micro‑control section, an automatic pressure‑replenishment module, and an electric pressure‑relief mechanism. The micro‑control section is governed by a microcontroller (MCU) and incorporates a high‑resolution, high‑speed 16‑bit sigma‑delta analog‑to‑digital converter, enabling real‑time communication with the computer. It can automatically adjust and maintain pressure, as well as perform automatic pressure relief. The software system interfaces with the pressure control unit via the computer’s RS‑232 serial port, offering a range of functions, including parameter configuration, calibration, pressure release, zeroing, amplitude adjustment, generation of test curves, storage of test records, and printing of test reports.

The TG-28 hydrostatic burst testing machine for pipes is designed to determine the pressure‑resistance failure time or the maximum burst pressure of thermoplastic and composite pipes—such as PP‑R, PP‑B, PP‑A, PE, PE‑X, PVC, PVC‑U, PVC‑C, and aluminum‑plastic composite pipes—under prolonged exposure to constant internal pressure and temperature. The test automatically stops when the pipe or fitting ruptures or upon completion, and it can save pressure‑time curves and generate printable test reports. This cost‑effective, versatile, and highly automated testing instrument is widely used by inspection agencies, research institutions, and pipe manufacturers.

Instrument features:

1. This single device is versatile: it can perform long-term hydrostatic pressure testing of pipelines, conduct pipe burst tests, and measure the thermal stability of thermoplastic pipes.

2. This instrument features comprehensive software control, providing real-time display of pressure, time, and system status, while simultaneously storing all parameter data. It can also identify eight distinct test states: pressurization, pressure compensation, depressurization, overpressure, running, completion, leakage, and rupture. The software automatically calculates time parameters such as “effective test duration,” “invalid time,” and “remaining time.” Furthermore, it dynamically adjusts the relationship between the “set time” and the “effective time,” ensuring that the test automatically terminates only when the “effective time” reaches the “set time.” A rich, user-friendly software interface and multilingual support cater to users from diverse countries and regions.

3. This unit employs embedded‑computer control, featuring a 19‑inch large‑screen display that enables the entire operation to be performed without connecting to an external PC or computer, ensuring convenient and straightforward operation. Each workstation is independent, allowing standalone use. The system offers three levels of monitoring: Level 1 provides minute‑by‑minute surveillance over a 1‑hour period; Level 2 offers 48‑hour holiday‑mode monitoring; and Level 3 delivers comprehensive, end‑to‑end monitoring, including constant‑temperature medium‑temperature control. It incorporates eight key functions: leak‑prevention alerts, rupture detection, real‑time monitoring, pressure‑retention during power outages, power‑failure protection, automatic recovery upon power restoration, as well as printing and data‑storage capabilities for test results.

4. Pressure control is stable, featuring multi-stage pressure‑accumulation regulation for consistent, constant pressure. It employs 0.5‑mm‑diameter, high‑precision solenoid valves from Taiwan, ensuring no clogging and long service life. Test pressure accuracy is high, achieved through the use of well‑known domestic pressure transmitters. The pressure control range is wide, spanning from 0.4 MPa up to full scale.

5. This instrument allows you to configure pre‑treatment settings, and the test will automatically start once pre‑treatment is complete. The pressure unit can be freely switched among MPa, bar, and psi, accommodating the operational preferences of users in different countries.

6. The host control system of this unit can be networked with the constant‑temperature bath control system, enabling simultaneous management of temperature settings, start/stop of tests, and other functions. Operation is straightforward and user‑friendly. This instrument accommodates a wide range of pipe diameters, suitable for testing pipes with outer diameters from Ф10 mm to Ф1600 mm. The device boasts excellent safety performance, with comprehensive protective measures in place across electrical, mechanical, and software components. It features password protection to prevent unauthorized personnel from performing improper operations. The instrument is aesthetically pleasing, with quick‑connect fittings between systems, facilitating easy assembly while ensuring safety and reliability, all within a compact footprint.

7. This pressure station can be operated independently and functions as a self-contained unit; a single station can connect to multiple pressure units. Key components feature imported pump bodies, delivering high pressure, large flow rates, and stable performance. The bladder-type accumulator ensures stable energy storage, reduces power consumption, and provides reliable pressure compensation. Additionally, the system can automatically replenish water by connecting to an external pressurized softened‑water supply, thereby guaranteeing consistent overall pressure.

Type A Test Fixture for Tubing Product Introduction:

This fixture is designed for use with hydrostatic burst testing machines for pipes. It is an A‑type plastic pipe pressure‑testing clamp that securely holds the pipe and serves as a critical auxiliary component of such testing equipment. The clamp features a collet with internal serrations; when the collet’s screw is tightened, the collet contracts, causing its serrations to engage the outer surface of the specimen and firmly secure it. The connecting screw further tightens the collet around the specimen. This fixture is suitable for end‑sealing various types of pipe and fittings, including those made of PE, PVC, PP‑R, and steel‑reinforced composite materials.

Product Features:

1. A cast A‑type structural fixture, eliminating the need for an intermediate tie rod and offering superior pressure resistance.

2. The patent’s structural design enables an assembly process in which clamping precedes sealing, achieving a 100% success rate for single‑clamping sealing.

3. Radial sealing, with a wide range of applicable pipe materials (suitable for PE, PVC, PP‑R, steel‑reinforced composite pipes, and more).

4. Split‑flap jaw‑clamping structure, easy to install and capable of automatic centering.

5. The large-diameter fixture accommodates a wide range of pipe diameters; specimens do not require reshaping prior to testing and can be easily inserted into the end cap.

6. The fixture body is lightweight, and each individual component is equipped with lifting devices, facilitating easy handling and quick, convenient assembly for testing. No specialized clamping equipment is required, resulting in high operational efficiency and low long-term operating costs. For test fixtures used with pipe diameters of Φ200 and above, the assembly time must be less than 30 minutes; for Φ200 and below, the assembly time must be less than 10 minutes.

7. The casting fixture is made of 304 stainless steel and, after casting, undergoes pickling and passivation treatments, providing excellent corrosion resistance and a long service life.
