Instrument Overview
This fixture is suitable for the static hydraulic blasting test machine for pipes, and is an A-type plastic pipe pressure test fixture that can firmly clamp pipes. It is a key accessory of the plastic pipe pressure test machine. It is a sleeve with inverted teeth inside. When the screws of the sleeve are tightened, the sleeve is retracted, and the inverted teeth of the sleeve are embedded in the outer wall of the sample, clamping the sample. The connecting screw can clamp the clamp onto the specimen. Can be applied to PE PVC、PP-R、 End sealing of various pipe fittings such as lined steel skeleton composite.
2、 Instrument characteristics
Casting A-type structural fixtures without the need for intermediate pull rods, with high pressure resistance.
The patented structure realizes the assembly method of clamping first and then sealing, with a success rate of 100% for one-time clamping and sealing.
Radial sealing, suitable for a wide range of pipe materials (suitable for PE PVC、PP-R、 Inner lining steel frame composite pipes and other pipes)
Split tooth clamping structure, easy to install, and can achieve automatic centering.
The large-diameter fixture is suitable for a wide range of pipe diameter changes, and the sample does not need to be shaped before testing, making it easy to insert into the head.
The specific weight of the clamp is light, and each individual component is equipped with a lifting device, making it easy to handle and assemble during testing. There is no need for a dedicated clamping device, resulting in high work efficiency and low long-term usage costs. The assembly time of the large diameter test fixture with a diameter of over 200 should be less than 30 minutes, Assembly time for tools with a diameter of 200 and below should be less than 10 minutes.
The casting fixture is made of 304 stainless steel material, which undergoes acid washing and passivation treatment after casting, and has strong rust prevention and corrosion resistance, with a long service life.
Hanging chain device to avoid the problems of thin-walled tube specimen rupture and difficulty in lifting the bottom fixture; Provide hooks with fixtures for easy hanging.
The fixture is marked with model information.
