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 巢穴, 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

How to clean and maintain stainless steel connect clamp to avoid water stains and fingerprints?

Use an all-purpose cleaner, glass water or detergent with a wet towel to clean the water marks, dust, oil, etc. on the surface of stainless steel, and then wipe the water with a clean, non-linting towel. The mirror-finished stainless steel surface does not need to be oiled, but the matte stainless steel needs to be oiled. When oiling, put the stainless steel oil in a small spray pot, spray it on the towel or stainless steel surface, and apply it evenly.

Daily maintenance. The mirror-finished stainless steel surface can be regularly wiped off with glass water or other detergents or a wet towel to remove fingerprints, watermarks, ash stains, etc., and then wiped with a non-linting cloth; after the matte stainless steel is oiled, if there are fingerprints or dust, use a clean cloth containing a small amount of stainless steel oil to wipe it until it is bright.

S Store in a dry and ventilated place, avoid humid environment, which can prevent stainless steel from rusting. Avoid contact with acid and alkali substances. Avoid contact with acid and alkali substances to prevent corrosion of the surface. Avoid heavy pressure and bumps. Avoid heavy pressure and bumps to prevent deformation and damage. Regular cleaning. Always keep it clean, clean up oil and dirt in time, and avoid rust caused by long-term residue. Use the right detergent. Avoid using detergents containing acid or alkali, and use neutral detergent or soapy water. Regular maintenance. Apply stainless steel maintenance agent regularly to form a protective film to increase wear and corrosion resistance.

Deal with rust. If you encounter rust, gently wipe it with a wire brush or sandpaper, then clean it with detergent or soapy water, and apply rust inhibitor or maintenance agent. By following these methods, you can extend the service life of stainless steel products and maintain their beauty.

巢穴 also has arrangements in this regard. Before packaging, DINSEN's stainless steel products have dedicated workers to apply maintenance oil to the products to ensure that the products are clean and beautiful. After being dried in the sun, the products are put into packaging again and packed into boxes for transportation.
