To a certain extent, the design and piping of the honed pipe should be consistent with the hydraulic schematic diagram. To a certain extent, other components, components and accessories other than the honed pipe itself should be carefully selected. Secondly honed tube arrangement and laid to must be neat, level also need to be clear, if the system at the same time, the existence of the parallel and cross honed tube, it is important to note that the gap size between them.
Honed tube with its good performance even when in use, to a certain extent, such as the rigidity, vibration resistance, etc., in order to improve the safety of the cloth tube stability, also need to configure the corresponding support and pipe clamp, avoid in the process of using them
Definition of honed quality control
Conditioning treatment of honed tube is refers to the pipe for high temperature tempering after quenching, when making use of its main purpose is very simple, in the operation is to make the honed after quenched and tempered pipe with excellent comprehensive mechanical properties. In the whole process, as a key modulation is the process of heating time and holding time, cooling rate and cooling medium parameters, these are all depends on the specific materials, the specific technical requirements. After tempering treatment of honed tube really great changes have taken place, it can not only keep higher strength, at the same time also has the very good plasticity and toughness, better meet the demand of different conditions of application.
How to press the honed pipe
1． Cutting off stage: so at the beginning of the constant pressure of honed due to the hole wall roughness, when making use of its oil stone and hole wall contact area is small, large contact pressure, hole wall bulge was quickly. And sharpening stone surface due to the large contact pressure, plus the chip for sharpening stone adhesive abrasion, abrasive and adhesive bonding strength decreased, thus some abrasive cutting pressure under the action of self-releasing, oil stone surface is exposing new grinding grain, this is known as the oil-stone self-sharpening.
2． Crushing and cutting stage: with the honed, the surface of the hole becomes more and more smooth, the contact area with the pumice increases, the contact pressure of the unit area decreases, and the cutting efficiency decreases. At the same time, the cuttings cut off are small and fine, and these cuttings have little wear and tear on the binder. Therefore, the abrasive particles of oil and stone fall off very little. At this time, the grinding is not by new abrasive particles, but by the cutting point of the abrasive particles. As a result, the grinding tip is under heavy load, and the grinding particle is easy to break and break, forming a new cutting edge.
3． Cutting phase jam: continue honed oilstone and holes on the surface of the contact area is more and more big, the chip of very fine accumulation between oil stone and wall of hole is not easy to rule out, block, oil stone become very smooth. Therefore, the cutting ability of oilstone is extremely low, which is equivalent to polishing. If the honed continues and the masonry is blocked seriously, the masonry completely loses its cutting ability and becomes seriously hot. The precision of the hole and the surface roughness will be affected. The honed should be finished as soon as possible.
