Frequently Asked Questions
What kind of corrosion-resistant treatment is applied to the fixture surface, and how does it enhance the product's service life?
The fixture surface is treated with an electrophoretic anti-corrosion coating, which forms a dense protective layer to resist chemical erosion from test media and environmental oxidation. This treatment extends the fixture's service life by over 30% compared with conventional plating processes.
What is the maximum test pressure that the fixture can withstand without deformation or leakage?
Depending on the model, the fixture can endure a maximum test pressure of up to 20 MPa, maintaining structural integrity and zero leakage even under long-term high-pressure loading conditions.
What is the operating temperature range of the fixture, and can it adapt to high-temperature hydrostatic testing scenarios?
The fixture has a stable operating temperature range of -10℃ to 120℃, which is fully compatible with high-temperature hydrostatic testing requirements for thermoplastic pipes such as PE-RT and PPR.
What is the installation tolerance of the fixture when matching pipes of different diameters, and how does it ensure sealing reliability?
The fixture features an installation tolerance of ±0.5 mm for pipe diameter matching. Its flexible sealing ring design can automatically compensate for minor dimensional deviations of pipe ports, ensuring consistent sealing performance.
How many times can the fixture's sealing components be reused before replacement, and what factors affect this service cycle?
The sealing components of the fixture can be reused for more than 500 test cycles under standard operating conditions. The service cycle is mainly affected by test pressure intensity, temperature fluctuations, and the cleanliness of pipe port surfaces.
