DINSEN Excellent characteristics of pipeline connectors beyond tradition

1.Good sealing.

DINSEN stainless steel ferrule pipe connectors can withstand pressures of 16 bar to 50 bar, and can withstand temperatures up to 280 degrees. Special requirements can withstand pressures of dozens of bars, which are suitable for more than 80% of pipelines in various industries. The pressure on the sealing ring is much lower than its elastic limit, and the preload is only 2kg/square centimeter, which is much lower than the flange gasket, and its preload is 70kg/square centimeter. In addition, the pressure-equalizing hole ensures that the sealing effect is proportional to the pipeline pressure, so it can meet the requirements of long-term durability and continuous and reliable sealing, and is not prone to "three leaks". Its service life can reach 20 to 25 years within the specified applicable range. In addition, the rubber lining ring used can withstand 107 to 108 doses of Y-rays, making it applicable to nuclear power circuits;

and the fluid in the pipe mainly passes through the pipe itself and the rubber ring at the connection, and it is difficult to produce electrochemical corrosion with the metal shell of the connector, which are all measures to ensure reliable sealing.

2. Vibration reduction, impact resistance, and noise reduction.

This connector changes the traditional rigid connection into a flexible connection, making the pipe system in a state of shock resistance and noise elimination. The connector itself can withstand an acceleration impact of 350 grams within 0.02 seconds; compared with the flange method, the noise intensity can be reduced by 80%; it is conducive to the safe and normal use of the entire pipe system including pumps, valves, instruments, etc., and prolongs its life.

3. Reduce the weight of the pipe system.

Compared with the flange method, it can reduce the weight by about 75%.

4. Save pipeline space.

Installation and disassembly do not require full-circle construction of flange type, only need to tighten the bolts from one side, so it can save 50% of pipeline layout and construction space, which is of great significance for ships with limited space and small installation space to reasonably configure the pipe system. The flexible connection allows a maximum angular deflection of 5° in all directions, and the spacing between pipe ends can reach 5mm to 35mm, etc. The loose tolerance range avoids the high-precision assembly requirements. No matter the installation deviation or the offset caused by the operation of the equipment, it has no adverse effect on the connector.

5. Good compatibility and adaptability.

The connector is widely used in various metal pipes and composite pipes. It can be used for connecting pipes of the same material or different materials. There are no high processing requirements for the wall thickness and connection end surface of the connected pipes.

6.Convenient and quick installation.

The connector itself does not need to be assembled during on-site construction, and the connected pipes do not need to be adjusted and processed in a cumbersome manner. During installation, only a torque wrench is needed to tighten 1-2 bolts from one side according to the specified torque value, which is particularly easy to operate.

7.Convenient maintenance.

When repairing the pipeline, even if there is oil and water in the pipe, there is no need for welding or heating, and there is no risk of fire or explosion. The ring clamp type repair joint can be used to repair various damaged pipelines from the outside by wrapping.

8.High cost-effectiveness.

The construction cost of the connector is more economical than that of the flange. Although the single cost is slightly higher than that of the general flange, it has a long service life and a high cost-effectiveness. On copper-nickel alloy and stainless steel pipelines, the single cost is lower than or close to that of medium-diameter copper-nickel alloy flanges and stainless steel flanges, and the cost-effectiveness is higher.

9.Convenient for computer-aided design.

Since there is no need lo consider the empty cicumference of the ange, etc., computer-aided design is simpler, which can easily promole modular design, simplify piping flow charts, etc., and reduce design and construction costs.

1.Check the logo: Generally, there will be relevant engraved logos on the real 316 stainless steel products.
2.Use reagent reaction: Since the biggest difference between 316 and 304 stainless steel is that 316 contains molybdenum (Mo) element, while 304 does not, we can use the principle that the molybdenum complex turns brown (black) to detect whether it contains molybdenum element. This reagent is usually composed of a mixed solution of ammonium sulfate, sodium sulfate, silver nitrate and copper nitrate.
3.Use a spectrometer: A more professional method is to use a spectrometer to detect the element content of the stainless steel material to determine whether it is 316 stainless steel.
4.Use salt spray test: This is a more professional detection method, which determines the material by observing the corrosion behavior of the material in a specific environment.

In the video updated by LA GUARIDA, the staff used stainless steel testing liquid for testing. Firstly, the DINSEN staff removed the impurities on the surface of the stainless steel connect couplings, and then used a special battery to operate. The positive pole of the battery was placed on the metal surface, and the negative pole was placed on the surface of the test liquid. After power was turned on, the color was used to determine whether the material was 316.

Experimental results:

The test liquid turns orange-red, and the nickel content is ≥7.8%. The material is 304 or above;
The test liquid is yellow or colorless, and the nickel content is <6.5%. The material is 301 or below.

As can be seen from the video, the test liquid is orange-red, which means it is 304 or above

Cómo limpiar y mantener el acero inoxidable abrazadera de conexión ¿Cómo evitar manchas de agua y huellas dactilares?

Use un limpiador multiusos, agua para vidrio o detergente con una toalla húmeda para limpiar las marcas de agua, el polvo, el aceite, etc., de la superficie de acero inoxidable. Luego, seque el agua con una toalla limpia que no deje pelusa. La superficie de acero inoxidable con acabado espejo no necesita aceite, pero el acero inoxidable mate sí. Para aplicar el aceite, vierta el aceite en un pequeño pulverizador, rocíelo sobre la toalla o la superficie de acero inoxidable y aplíquelo uniformemente.

Mantenimiento diario. La superficie de acero inoxidable con acabado espejo se puede limpiar regularmente con agua para vidrio, otros detergentes o una toalla húmeda para eliminar huellas dactilares, marcas de agua, manchas de ceniza, etc., y luego con un paño que no deje pelusa. Después de aceitar el acero inoxidable mate, si hay huellas dactilares o polvo, utilice un paño limpio con un poco de aceite para acero inoxidable para limpiarlo hasta que quede brillante.

S Almacenar en un lugar seco y ventilado, evitando ambientes húmedos, lo que puede prevenir la oxidación del acero inoxidable. Evitar el contacto con sustancias ácidas y alcalinas. Evitar el contacto con sustancias ácidas y alcalinas para prevenir la corrosión de la superficie. Evitar presiones y golpes fuertes. Evitar presiones y golpes fuertes para prevenir deformaciones y daños. Limpieza regular. Mantener siempre limpio, eliminar el aceite y la suciedad a tiempo y evitar la oxidación causada por residuos persistentes. Usar el detergente adecuado. Evitar el uso de detergentes que contengan ácidos o alcalinos, y usar detergente neutro o agua jabonosa. Mantenimiento regular. Aplicar regularmente un agente de mantenimiento de acero inoxidable para formar una película protectora que aumente la resistencia al desgaste y la corrosión.

Limpie el óxido. Si encuentra óxido, límpielo suavemente con un cepillo de alambre o papel de lija, luego con detergente o agua jabonosa y aplique un inhibidor de óxido o un agente de mantenimiento. Siguiendo estos métodos, puede prolongar la vida útil de los productos de acero inoxidable y mantener su belleza.

LA GUARIDA También cuenta con acuerdos al respecto. Antes del embalaje, los productos de acero inoxidable de DINSEN cuentan con personal especializado que aplica aceite de mantenimiento para garantizar su limpieza y buen estado. Tras secarse al sol, se vuelven a empaquetar y se embalan en cajas para su transporte.
