FAQ:
Q: What is the applicable pipe diameter range of this hydrostatic fixture?
A: This fixture supports pipe specimens with diameters ranging from DN20mm to DN630mm, covering mainstream plastic and composite pipe specifications.
Q: What type of sealing technology does this fixture adopt?
A: It employs a radial compression sealing mechanism, which ensures reliable hermetic closure for PE, PVC, PP-R and steel-lined composite pipes.
Q: What is the primary material of the fixture’s main body?
A: The core structural components are fabricated from high-strength stainless steel or carbon steel, featuring excellent corrosion resistance and pressure-bearing capacity.
Q: What is the maximum working pressure this fixture can withstand?
A: The fixture’s rated operating pressure reaches up to 16MPa, fully meeting the requirements of hydrostatic tests, bursting tests and negative pressure tests.
Q: What are the key modular components of this fixture?
A: It consists of a modular base assembly, high-performance sealing gasket, pressure ring, locking clamp, compression fasteners and exhaust valve, with a detachable and easy-to-maintain structure.
