Product Overview

1. High-quality materials, strong and durable

Selected stainless steel materials: SS304 and SS316 stainless steel are used. SS304 has good corrosion resistance, heat resistance and mechanical properties, and is suitable for general industrial and civil pipeline systems; SS316 adds molybdenum elements, which is more corrosion-resistant, especially suitable for marine environments and occasions with extremely high requirements for corrosion resistance.

High material reliability: These materials have good strength and toughness, can withstand certain pressure and external forces, are not easy to deform or damage, and ensure long-term stable use in pipeline systems.

 

2. Exquisite design and reliable connection

Hexagonal head design: The unique hexagonal head design facilitates installation and disassembly using tools such as wrenches, provides better torque transmission, and makes the installation process more labor-saving and efficient.

Internal and external thread matching: The male and female thread design is adopted, which is tightly connected with the corresponding pipes or pipe fittings, effectively preventing fluid leakage and ensuring the sealing and stability of the pipeline system.

 

3. Excellent performance and wide application

Strong corrosion resistance: It can resist the erosion of various chemical media such as air, water, acid, alkali, salt, etc. It can maintain good performance in harsh working environments, reduce the corrosion risk of pipeline systems, and extend service life.

Good high temperature resistance: It can still maintain stable performance under certain high temperature environments, and is suitable for some pipeline systems that need to transport high-temperature fluids.

Strong pressure bearing capacity: It can meet the different pressure requirements of various industrial and civil pipeline systems, and has stable pressure bearing capacity at different temperatures.

 

4. Diversified application fields

Industrial pipeline system: It is widely used in pipeline systems in the petroleum, chemical, natural gas, papermaking, nuclear energy and other industries. It is used to connect pipelines of different diameters or different materials to achieve fluid transmission and distribution.

Commercial and civil facilities: It is also widely used in the pipeline connection of building water supply and drainage systems, HVAC systems and food and beverage processing equipment, such as pipeline systems in hotels, shopping malls, hospitals and other places.

 

5. Strict quality control, quality guaranteed

Strict production standards: During the production process, the products strictly follow relevant international standards and industry specifications, such as ISO 9001 quality management system certification, to ensure that each coupling meets quality requirements.

Strict quality inspection: After strict quality inspection, including raw material inspection, processing inspection and finished product inspection, the product quality is stable and reliable, without defects and hidden dangers.

   Main Parts
 

         Function and purpose

Variable diameter connection of pipelines: In various pipeline systems, when it is necessary to connect pipes of different diameters together, variable diameter core plays a key role. In the water supply and drainage pipeline system, DN15 water pipes can be connected to DN20 water pipes through variable diameter connections.
Convenient appliance connection: Through threaded connection, it can be easily connected to various water appliances and valve gauges, making the installation and use of pipeline systems more flexible and diverse. For example, in home decoration, it can be used to connect faucets, angle valves, and water pipes of different diameters.         

 

Material classification

Zinc alloy variable diameter joint: generally made by die-casting and other processes, the surface is often treated with electroplating zinc, nickel chromium plating and other methods. It has a beautiful appearance, tight structure, high strength, good sealing, shock resistance, anti-corrosion, waterproof and dustproof advantages, and is suitable for ordinary pipeline connection scenarios where corrosion resistance requirements are not particularly high.
Copper nickel plated core: Copper itself has good ductility and conductivity, and after nickel plating treatment, its corrosion resistance is further enhanced. This type of core repair is finely crafted, with clear and burr free threads, explosion-proof and leak proof, and strong pressure resistance. It is commonly used in water and gas transportation pipeline systems that require high connection stability, such as variable diameter connections for household plumbing pipelines and pipeline variable diameter connections in industrial fields such as chemical, petroleum, food, and pharmaceutical industries.
Stainless steel reducers: Variable diameter bushings made of materials such as 304 stainless steel, 316L stainless steel, etc., have excellent corrosion resistance, high temperature resistance, and high strength, and can maintain stable performance under harsh environmental conditions. They are widely used in pipeline systems in industries such as chemical, pharmaceutical, food and beverage, water treatment, and some places with high hygiene requirements.

characteristic

High pressure resistance: Made of stainless steel material, carefully processed and manufactured, it can withstand high pressure and is suitable for high-pressure pipeline systems.
Strong corrosion resistance: Stainless steel materials such as 304 and 316 have good corrosion resistance and can resist the erosion of non corrosive or corrosive media such as oil, water, and gas, extending their service life.
Reliable connection: Through threaded connection, the steel pipe and the core are directly connected and sealed, with a firm connection and good sealing performance, which can effectively prevent liquid or gas leakage inside the pipeline.
Easy installation and maintenance: When connected to steel pipes, there is no need for welding, and they can be directly screwed in. The operation is convenient and fast, which is conducive to fire prevention, explosion prevention, and high-altitude operations, and also facilitates later installation, maintenance, and upkeep

 

application area 

Municipal engineering: In the laying of urban water and gas supply pipeline networks, changes in pipe diameter are often encountered. Variable diameter core filling can ensure the integrity of the municipal pipeline system and ensure the normal transportation of water, gas, etc.
Chemical industry: In chemical production, pipeline diameters vary between different processes. Variable diameter core filling can help connect pipelines of different diameters, enabling safe and efficient transportation and circulation of various chemical raw materials and products, meeting the needs of the entire production process.
Power engineering: widely used in domestic large-scale power station supporting projects to ensure the smooth transmission of various energy media such as steam, cold water, hot water, oxygen, etc. in pipelines of different diameters.
Oil drilling: such as variable diameter roller square bushing, is a key component of the oil drilling rig that simultaneously applies force in both directions of transmission torque and footage during rotary drilling. It can be effectively applied to various specifications of square drill rods, extending the service life of square drill rods and reducing drilling costs.
Building water supply and drainage: In the building's water supply and drainage system, it is used to connect pipes of different diameters to ensure the normal supply and discharge of water, such as in areas such as bathrooms and kitchens.
