海角视频's double ferrule tube fitting is a leak free connection suitable for instrument applications. The double ferrule tube fitting is designed according to high-quality standards, with a wide range of available sizes, materials, and specifications. The working principle of the double ferrule tube fitting is to insert the seamless tube into the ferrule, lock it with the nut, resist the double ferrule, and cut into the tube to seal it. It does not require welding or manual loading and unloading when connected to seamless tubing, which is beneficial for fire prevention, explosion prevention, and high-altitude operations, and can eliminate the drawbacks caused by careless welding. So it is a commonly used connector in the piping of automatic control devices in refining, chemical, petroleum, natural gas, food, pharmaceutical, instrumentation and other systems. Suitable for connecting pipelines such as oil, gas, and water. 海角视频 double ferrule tube fittings have passed multiple certifications including BV, ABS, ISO, DNV, RS, and CE.
Advantages of Double Ferrule Tube Fitting
Manufacturing standards
Our products are made entirely according to American standards from material selection to craftsmanship, and can be fully interchangeable with major brands, such as Swagelok double ferrule tube fittings and Parker double ferrule tube fittings
01
Pressure resistance and sealing performance
The edge of the back ferrule has undergone specialized heat treatment, with a hardness of HV800 or above, and can penetrate the surface of the pipe by more than 0.3mm, effectively preventing pipe pulling.
The two seals of the front and rear ferrules effectively ensure the sealing and pressure resistance performance under high pressure.
02
Reinstallation performance
Practice has proven that the 海角视频's double ferrule tube fitting can be repeatedly disassembled and installed no less than 10 times, while still maintaining high voltage resistance performance.
03
Installation torque
The nuts of the 海角视频 double ferrule tube fittings are all coated with silver and have added their own patented sealing layer, ensuring that the installation torque is controlled within a reasonable range. Especially in narrow spaces or aerial operations, making installation very easy.
04
Cost performance
The 海角视频 double ferrule tube fitting has quality and performance that does not belong to major brands, and has the price advantage of Chinese products. Therefore, it has a high cost performance advantage.
05
What are the advantages of double ferrule tube fitting with a seamless tubing ?
The double ferrule tube fitting provides a reliable, leak proof and sealed connection to prevent serious losses caused by vibration, leakage, thermal shock, and incorrect installation.
The double ferrule tube fitting has leak proof sealing performance. If installed on a high-quality tubing, the double ferrule tube fitting will not leak even under harsh working conditions. Because this type of double ferrule tube fitting relies on metal to metal mechanical hard sealing. By tightening the tube fitting nut, the double ferrule can be cold pressed onto the double ferrule to achieve a sealing effect.
The double ferrule tube fitting is detectable, and after initial installation, using a gap detection gauge can ensure that the installation or inspection personnel ensure that the double ferrule tube fitting is fully tightened. If the nut has been properly tightened, the inspection gauge cannot be placed between the hexagonal end of the nut and the fitting body. Simple installation and consistent initial installation detectability greatly reduce installation errors.
The 海角视频 double ferrule tube fittings series has passed ASTM mechanical joint prototype testing and obtained various classification society certificates. 海角视频 adopts advanced low-temperature carburizing technology to provide reliable guarantee for the practical application of the ring. The inside of the nut is silver plated to avoid jamming during installation. The thread adopts a rolling process to improve the surface hardness and smoothness, while also extending the service life of the pipe fittings. This series of products has excellent sealing performance, stable connecting components, can resist strong earthquakes and extreme working conditions, convenient fitting installation, and can achieve multiple repeated disassembly and assembly. The entire series of 海角视频 double ferrule tube fittings have passed multiple experimental tests such as vibration testing and pneumatic testing, ensuring the safe and reliable connection of each product leaving the factory.
海角视频 is one of the leading professional manufacturers of instrument valves and accessories in China. We have strict material selection testing and high standard processing technology, smooth production process control, and professional production inspectors to safeguard our products, creating hundreds of high-quality valves and fittings. 海角视频 is your best choice for one-stop shopping, saving time and effort.
海角视频 has won unanimous praise from customers for its professional management, mature technology, and sincere service.
Applicable scenarios and industries of double ferrule tube fittings
海角视频 double ferrule tube fittings are used in precision instrument pipelines, measurement pipelines, as well as harsh working conditions such as high temperature, high pressure, high corrosiveness, ultra-high pressure, ultra-low temperature, etc. in industries such as semiconductors, petroleum, chemical, metallurgy, power, nuclear power, ships, and marine engineering.
The application of stainless steel seamless pipes in the petrochemical industry:
Stainless steel seamless pipes generally meet the requirements of various harsh working environments through material selection and process optimization, and are the preferred solution for modern industrial pipeline systems. Stainless steel seamless pipes have a wide range of applications in the petrochemical industry, mainly due to their excellent corrosion resistance, high strength, high temperature and high pressure resistance, and good processing performance.
1. Main application scenarios of seamless pipes:
(1) High temperature and high pressure environment: refining unit, ethylene cracking unit
(2) Transport of corrosive media
(3) Heat exchange equipment: widely used in condenser, reboiler and other heat exchange equipment.
(4) Instrumentation and Control System
(5) Other key equipment: reactor internals, LNG low-temperature pipelines
2. Commonly used stainless steel materials
-Austenitic stainless steel:
-304/304L: Universal type, used in general corrosive environments.
-316/316L: containing molybdenum, resistant to chloride corrosion, suitable for seawater or high salt environments.
-321/347H: containing titanium or niobium, resistant to high temperature oxidation, used for heating furnace tubes.
-Dual phase stainless steel (such as 2205, 2507): combines high strength and resistance to chloride stress corrosion, suitable for harsh environments (such as subsea pipelines).
-High nickel alloys (such as Inconel 625, 825): used for extreme corrosion conditions.
3. Core advantages of seamless pipes:
-Corrosion resistance: Resist common electrochemical corrosion, intergranular corrosion, and stress corrosion cracking in the petrochemical industry.
-High strength: Seamless process without any weak points in the weld seam, with better pressure bearing capacity than welded pipes.
-Cleanliness: Smooth inner wall, not prone to scaling, suitable for high-purity media (used in the food and pharmaceutical industry).
-Longevity: Reduce downtime maintenance frequency and lower overall lifecycle costs.
4. Industry standards and certifications
-International standards: ASTM A312 (austenitic stainless steel pipe), ASTM A790 (duplex seamless steel pipe), API 5LC (corrosion-resistant alloy pipeline pipe).
-Domestic standards: GB/T 14976 (Seamless Stainless Steel Pipes for Fluid Transport), GB 9948 (Seamless Pipes for Petroleum Cracking).
-Special requirements: Must pass tests such as sulfide stress corrosion (SSC) and intergranular corrosion (GB/T 4334).
So stainless steel seamless pipe is a key material in the petrochemical industry, especially irreplaceable in high temperature, high pressure, and corrosive environments. With the development of petrochemical processes towards high efficiency and environmental protection, the demand for high-performance stainless steel seamless pipes will continue to increase. Customers need to comprehensively consider factors such as medium characteristics, temperature, pressure, and cost when selecting, and strictly follow relevant standards.
