The advantages of pressing stainless steel pipe fittings

With the application of new materials and new technologies in installation engineering and the continuous improvement of water quality requirements for hot water supply and domestic water supply, especially water quality issues, people pay more and more attention to it, and the requirements for pipelines are also increasing. From galvanized steel pipes - plastic pipes (PP-R) - composite pipes - to copper pipes, to stainless steel pipes that are now vigorously promoted, they are constantly updated and upgraded. Stainless steel clamping pipe fittings can meet the national hygiene standards for direct drinking water and can be 100% recyclable.

Among them, the stainless steel water pipe clip connection method can be said to be a very popular installation method by industry professionals, installation workers and consumers. It relies on the unique clamping principle, one-step installation in place, the construction efficiency is very high, which can make the stainless steel water pipe and pipe fittings closely connected, no water seepage, no water leakage.

First, let's understand the characteristics of pipe connection methods of different materials of the lower pipe.

Threaded connection is suitable for galvanized iron pipes, the pipes using threaded connections need to be thick enough to be threaded for thread feeding, the wall thickness of galvanized iron pipes is high, and there is no problem in completing the thread supply treatment. The clamping connection is also completely fine in the face of the thickness of galvanized iron pipes. At present, the minimum wall thickness of stainless steel pipes has reached 0.6-0.8mm, and the threaded connection cannot meet the minimum wall thickness requirements of the tooth supply. If the threaded connection is used for installation, it takes a long time to use hemp wire or raw material belt, which will bring cost pressure to the construction.

PPR plastic water pipe adopts hot melt connection, use a hot melt machine to heat the pipe mouth and pipe fitting mouth, and then immediately connect the pipe mouth with the pipe fitting mouth, wait for the temperature to drop, and complete the hot melt connection. Its melting temperature needs to reach a high temperature of more than 1500 °C, not to mention whether the heating setting can be designed to a high temperature of more than 1500 °C, even if it can, it is extremely unsafe to build on site.

After a period of use, PPR plastic water pipes have serious secondary pollution on the inner wall of the pipe, which is easy to breed bacteria and pose a threat to human health, so it is not suitable for household water pipes.

The connection between PVC-U water pipe and pipe fittings is to use glue bonding, apply special glue to the pipe mouth, and then quickly connect the pipe fittings, and complete the bonding connection between PVC-U water pipes and pipe fittings after the glue dries. Can stainless steel water pipes be glued together? There are also many metal-specific glues available online.

Stainless steel water pipes are connected with glue, which is not feasible, why? Because stainless steel water pipes are not only used for daily tap water, but also for hot water, and when glue connection is used for hot water, the glue will lose its adhesive effect for a period of time after being heated, even PVC-U water pipes, will not be used for hot water pipes in the decoration project, because it is easy to deform and age after heating, and PVC-U water pipes will be degraded under high temperature ultraviolet rays, and the polypropylene contained in it will degrade, inhaled into the human body, and will seriously endanger human health.

Snap connection is a suitable connection method for stainless steel water pipes. Snap-on fittings can also be used for the connection of galvanized iron pipes. The pressing pipe fittings have built-in EPDM food-grade rubber sealing rings, which are more reliable than traditional threaded pipe fittings and hot melt pipe fittings. Installation connection is also very easy to install using a special clamping tool. It can be used with both hot and cold water, and there is no problem of glue adhesion falling off.

Stainless steel pipe is currently the safest and healthiest pipeline, its pipeline is recognized as food hygiene grade pipe, the material is safe and non-toxic, has no impact on water quality, and is not harmful to human health. It can ensure that household water is not subject to secondary pollution during transmission, and has a long lifespan and requires almost no maintenance, so it is recommended to use pressing pipe fittings for stainless steel water pipe connections.

01 Green and healthy

Stainless steel material is recognized as a healthy material that can be implanted into the human body, which can meet the national hygiene standards for direct drinking water, and can be 100% recycled.

02Reliable connection

The connection is reliable and safe, and the clamping connection has high strength and good vibration resistance. The connection part is "dead" at one time to avoid the possibility of loosening the "live joint".

03 Convenient construction

The construction is convenient and fast, avoiding on-site welding, wire nesting or rolling groove operations, as long as special hydraulic tools are used, the clamping connection can be easily completed, saving time, labor, cost, and the success rate of one installation is high.

04 Wide range of applications

The double clamping stainless steel water pipe has strong compatibility, and can be used with various pumps, valves, water meters and nozzles, etc., and can be used in various pipeline systems, and can be used for water supply, drainage, gas transmission and other purposes.

05 Large flow

The flow pressure loss is small, the inner diameter of the clamping pipe fittings is the same as the inner diameter of the pipe (equal diameter design), and the deformation of the pipe at the clamping part is small, so that the flow and pressure loss at the pipe connection are very small and negligible.

06 Reliable connection

The system is highly compatible, and the clamping pipe fittings have a complete range of specifications, which can be used with various valves, nozzles, water meters, pumps, etc., and can be connected with various existing pipeline systems.

07 Long service life

The service life of double clamping stainless steel water pipes can reach 50-70 years, and there is almost no need to maintain pipe fittings in the pipeline system, which saves the cost of daily maintenance and maintenance to a certain extent.

Part.01 Piping and blanking

The clamping equipment is assembled according to the instructions, and the pipe is cut according to the required pipe size, and the cutting of thin-walled stainless steel pipe should be cut without significant heating, and the cutting tool should be used with a special electric pipe cutter, manual pipe cutter or manual pipe cutter for scribing and cutting.

Part.02 Pipeline burr cleaning

After cutting the tube, to avoid burr puncture sealing, use a professional deburring or file to remove the burr completely.

Part.03 Pipeline markers

Before the Stainless Steel Press Fittings is inserted into the pipe fitting, it is necessary to draw an insertion depth marking line on the pipe to prevent the pipe from being inserted in place during construction, resulting in a decrease in the reliability of the clamping connection.

Part.04 Inspection of sealing rings

Check whether the sealing ring in the pipe fittings is contaminated or misaligned, and wipe the pipe fitting socket and the pipe port clean first, and there should be no debris such as water and oil covering it.

Part.05 Socket pipe

Insert the pipe straight into the fitting, be careful not to touch the rubber ring, and make sure that the end of the fitting is within 3mm of the scribing position.

Part.06 Extrusion and sealing operation

The annular concave part of the jaws of the clamping tool is aligned with the annular convex part of the rubber ring at the end of the pipe fitting.

It is precisely because the connection method of stainless steel water pipe clamping has the above characteristics, which is not only simple to install but also ensures the service life of the water pipe, and the construction team prefers to use clamping pipe fittings. Water pipes are a necessity of life, not only to choose peace of mind, but also to use peace of mind. In order to ensure the health of water residents and improve the quality of life of residents!
