What is stainless steel press fitting?

Press fittings is a kind of pipeline connect thchnology, it does not have thread, and also does not need welding or solder. Press fitting are made of stainless stee, carbon steel, copper and so on.

The principle of stainless steel press fittings

1. Sealing principle: The rubber O-ring shrinks radially and tightly.
2. Anti-pulling principle: the press part is deformed, and the middle is small and the two ends are large.
3. Anti-rotation principle: The card is pressed into a hexagonal shape and cannot be rotated.
4. Pipe material: (SUS304) (SUS316) (SUS316L).
5. Working pressure: ≤1.6MPa.
6. Working temperature: -20℃-200℃.
7. Connection method: Use special hydraulic tools for clamping connection.

The Characteristics of stainless steel press fittings

GD press fittings is very easy and quick to install and only uses AISI 316L stainless steel. Compared with others such as plastic, iron and copper and can provide a high resistance to corrosion.

The fittings used in pressfitting system have a to-roidal chamber at their own ends inside which there’s a O-ring, which has a very stong resis-tance against aging, it can resist to high pressures and also to temperature.

GD pressfitting, with electromechanical jaws are used for pressing the fittings on the tubes. The O-ring once compressed, guarantees the con-nection to be completely sealed and no longer divsisible.

Nowdays the GD pressfittings are produced with stainless steel, which is certainly the best material in security of hygiene compared with others such as plastic, iron and copper and can provide a high resistance to corrosion. Thanks to the long-term experience within the field of stainless steel production, we are now able to provide a competitivenses beyond comparison with excellent products, and we have acquired much more good reputation both domestic and abroad market.

The advantages of stainless steel press fittings

Green and healthy

Stainless steel material is recognized as a healthy material that can be implanted into the human body. It can meet the hygienic standards of direct drinking water in various countries, and can be 100% recycled.

Reliable and secure connection

The compression type connection has high strength and good vibration resistance. Instead of relying on threads, special hydraulic tools are used to achieve one-time forming, avoiding the possibility of loosening.

The construction is convenient and fast

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

Good hygiene and environmental protection performance

The pipes and fittings are all made of 304 or 316 stainless steel, and the sealing ring is made of EPDM rubber, chlorobutyl rubber, nitrile rubber or silicone rubber, which has good sanitation and environmental protection performance and long service life.

Small flow pressure loss

The inner diameter of the compression fitting is the same as the inner diameter of the pipe (equal diameter design), and the deformation of the pipe at the compression part is small, so that the flow and pressure loss at the pipe connection are very small and can be ignored.

Strong system compatibility

The compression fittings have a complete range of specifications and can be used with various valves, faucets, water meters, water pumps, etc., and can be connected with various existing pipeline systems.

Both surface and concealed installations are available

The press-type stainless steel piping system has a beautiful appearance and can be installed on the surface to improve the decorative effect, or it can be installed in the dark to meet the technical requirements of embedded installation.

Free update maintenance, superior economic performance

50-70 years of service life design and high reliability design, during the service life of the building, almost no need to update and maintain the pipeline system, save a lot of use costs, and reduce various losses to the limit.

Wide range of applications

It is suitable for civil low-pressure fluid transportation such as cold and hot water, direct drinking water, heating, air conditioning, fire fighting, gas, etc. It can also be used for low-pressure fluid transportation in medicine, beverage, food, chemical and other industries.

What is stainless steel press fitting application?

GD PRESS fitings are made of AISI 316L, these fittings widely used in potable water, cooling sysems, heating systems, solar, oi, gas, lubricants, ect. However, different media require different sealing ring.

Potable water and cooling system

Stainless steel is not easy to rust and can be recycled. It is a 100% environmentally friendly and healthy material that can be implanted into the human body. When used in direct potable water systems, EPDM material sealing ring is the best choice. The working temperature range is -20°C-120°C.

Heating and high temperature system.

If the sealing ring made of FKM material is selected, the working temperature range of the stainless steel press fitting is -20℃-200℃. The material characteristics and installation characteristics of stainless steel press fittings make it maintenance-free, and are very suitable for home heating pipelines.

Oil and gas

Stainless steel press fittings fitted with HNBR material sealing ring can be used to transmit oil and gas, such as, natural gas, lubricating oil, etc. The operating temperature range is -20°C-100°C. HNBR has good oil resistance (good resistance to fuel oil, lubricating oil, aromatic solvents); and due to its highly saturated structure, it has good heat resistance, excellent chemical corrosion resistance (for freon, acid , alkali has good resistance), excellent ozone resistance, high compression set resistance; at the same time, it also has the characteristics of high strength, high tear performance, excellent wear resistance, etc.

Other

Stainless steel has excellent properties such as high temperature resistance and corrosion resistance. It can be used in many fields with sealing rings of different materials. In addition to the three types of sealing rings mentioned above, there are also PTFE materials. With the development of press fittings, the scope of application will continue to expand, and correspondingly more sealing rings will appear.

What is the difference between M Press and B press fittings?

B< Press is a versatile press fitting system for use with hard, half hard or annealed copper tube. The unique press indicator ensures a secure, life long, leak-proof joint every time.

B< Press fittings are quick and easy to install and are available in copper and copper alloy. This flame-free range is designed with an innovative 3-point press system which ensures a secure, permanent leak-free joint that is suitable for multiple applications. >B< Press fittings are also compatible with a range of press tools and jaws.

M press is a hazard-free alternative to soldering copper pipework, with no open flame required to make a secure connection. M press is available in Stainless Steel, Carbon Steel, Copper and CuNiFe, and is suitable for use on supply systems including heating, cooling, gas and potable water.
