There is almost no need to consider the corrosion allowance of M profile stainless steel press fittings in tap water transportation. So, “thinning” has always been the direction of the stainless steel press fitting manufacturers to reduce the cost of M profile stainless steel press fittings. The key to thinning is the reliability of the connection.
The pipes and fittings are welded and produced under the double protection of the inert gas inside and outside at the workshop, and the quality is reliable; the installation operation is simple and easy to learn, and the operator is not demanding; the construction is convenient and not restricted by the working space.
The press connection requires relatively stable system pressure, but in real life, there are often high and sometimes low pipeline pressures, so the pressure strength needs to be improved; the production process of M profile stainless steel press fittings is complicated and requires high precision, especially it will take much labour and material to produce the inner hoop groove of O-ring sealing, which makes the price relatively expensive; the installation quality is closely related to the earnestness of the operators, the construction requirements are strict and meticulous, and it is not suitable for the extensive management of the construction site.
The forming of stainless steel press fittings is a relatively complicated production process, which needs to be welded according to the different uses and materials of the products. The forming of stainless steel press fittings needs to be carried out according to certain procedures, and the forming needs to be gradually formed under certain pressure. It is necessary to strictly abide by the corresponding process, otherwise, some stainless steel press fittings with certain quality problems may be produced. Among the press fittings, what is the M profile? What is the V profile? What is the difference between them before?
The meaning of the V profile: using the rigidity of the metal material and the elastic compression ratio principle of the sealing material, and at the same time making full use of the length of the socket, the pipe connection with clamps on both sides of the U-shaped groove of the pipe socket is called V profile. Advantages of V profile: V profile press fittings inherit all the advantages of press fittings and make up for the shortcomings of M profile press fittings during use. V profile press fittings are one of the reasonable and reliable connection methods among the domestic thin-walled metal pipe connections. It is widely used in many system fields such as direct drinking water, tap water, cold and hot water, heating, gas, and fire sprinklers, etc.
The meaning of the M profile: In terms of appearance, M profile press fittings are smaller than V profile press fittings. This is also the more intuitive difference between the M profile and V profile. It is precise because of this small pipe diameter that V profile have a better sealing effect than M profile, although their installation methods are the same.
The V profile press fitting is actually improved and evolved version of the M profile press fitting. The installation method is exactly the same. By extending this small section of the pipe diameter, the internal rubber ring is protected, and the sealing between the pipe fittings is effectively improved. The process of connecting and installing V profile and M profile is basically the same, but we must pay more attention when installing and using them, so as to avoid connection errors and affect our normal use.
Simply put, the M profile presses one side of the sealing ring, and the V profile presses both sides. Of course, V profile is better, there is no doubt.
