Advantages and characteristics of pincer sound tube

1, connected by special hydraulic tongs, without preparation work outside the construction site and equipment, simple and fast (5 times faster than the traditional method), easy to fix on the reinforcing cage and not affected by bad weather. 2, the length can be matched according to the requirements of the site, no loss. 3. This product is a patented product. Compared with similar products in the market, the tensile strength is higher, reaching more than 320Mpa (generally the tensile strength of other products is about 30Mpa). 4. Cost saving, preparation time saving, no need for technicians, loss saving (different types of short pipes can be customized according to customer requirements) and not limited by the site. 5. It is safe and does not need to be welded at the construction site. 6. Using the deformation of the pipe, the joint is clamped into two big ends and a small middle, so that the joint is stuck at one time and the possibility of loosening the joint is avoided. Whether in pull-out force or torque resistance, the performance is quite stable and excellent, and it bulges into a small convex arc, effectively avoiding collision with conduits, vibrators, etc.

Technical parameters of clamp-type sound tube: JT/T705-2007 standard visual inspection and hand inspection, the sound tube is free of burrs, cracks, scars, folding, delamination, lap welding defects, scratches, weld dislocation, burns and thin oxide scale. Bending is not more than 5mm/m, outer diameter 1.0%, wall thickness 5% (MP) ≥ 3 15mp, tensile strength test (elongation) ≥ 14%, flattening test. When the distance between the two pressure plates is 3/4 of the outer diameter of the sound tube, the crack bending test should not be carried out. The sound tube has no filler and the bending radius is nominal. Bending angle 120, sound tube without crack. When the water pressure injected into the seals at both ends of the acoustic tube is 5MP, the acoustic tube has no leakage and eddy current damage, the external pressure of the crack sealing test is P=2 15S/D, and the internal pressure of the interface without deformation is P=2 15S/D, and there is no leakage. Should be able to withstand a tensile force of 3000N for 60 minutes. There is no looseness and fracture in the vibration test of the connection part. Under the test pressure of 1.2MP, the vibration lasts for 654.38+ten thousand times, and there is no leakage or shedding of the joint. Torque test torque 120N.m duration 10 min, and joint non-slip hardness test HRB≥90.
