22691K 26791K series

The 22691K 26791K series is mainly used to achieve connection and steering between different components in pipeline systems, such as hydraulic systems, pneumatic systems, water supply and drainage systems, etc. Their presence can be seen. By connecting with hoses, hard pipes, etc., it is confirmed that hydraulic oil, water, gas and other fluids are stably transmitted, playing a key role in scenarios where the direction of the pipeline needs to be changed.

Material characteristics

Common materials include stainless steel, carbon steel, etc. Stainless steel joints have excellent corrosiveness and can work stably for a long time in harsh environments such as humidity, acidity, and alkalinity. They are not easily rusted or damaged and are suitable for industries such as chemical, food, and beverage industries that require high corrosion resistance (based on actual reports); Carbon steel material, after heat treatment, surface galvanizing or nickel plating, not only has high strength and hardness, can withstand high pressure, but also enhances rust prevention ability. It is commonly used in industrial manufacturing, engineering machinery and other industries.

structural design

Threaded connection part: Standard thread designs are usually used, such as British thread (G thread), American thread (NPT thread), etc., which can tightly fit with fittings with internal threads, protecting the sealing and firmness of the connection. The threads have undergone excellent processing, with fine tooth profiles and uniform pitch. Some products have also undergone special surface treatment to enhance performance and rust resistance.

Bending section: The bending angle is commonly 90 °, and other angle specifications are also available for special needs. The inner and outer walls of the elbow are well processed, with smooth inner walls, which can effectively reduce the resistance of the fluid at the turning point, reduce energy loss, and protect the smooth flow of the fluid; The outer wall has a certain thickness and strength to withstand fluid pressure and external forces.

Easy to install structure: equipped with hexagonal or other shaped nut parts for easy installation and operation, making it convenient to use tools such as wrenches for installation and disassembly, confirming the ease and effectiveness of operation during construction, and protecting the joint from uniform stress during installation to prevent damage.

performance parameters

Work pressure: The range of work pressure varies depending on the material, specifications, and structure. Generally speaking, low-pressure models can withstand pressures of 1-5 MPa, while medium to high-pressure models can withstand pressures of 10-50 MPa or even higher, meeting the pressure requirements under different working conditions.

Applicable temperature range: Conventional products are suitable for temperatures around -20 ℃ -100 ℃. If special materials and processes are used, the applicable temperature range can be expanded to -40 ℃ -150 ℃ to adapt to different working environments.

Pipe diameter adaptation: Provides multiple specifications to accommodate pipes with different inner and outer diameters, ranging from a few millimeters (for fine instrument fluid transmission) to tens of millimeters (for industrial large-scale pipeline systems).

Application scenarios

Industrial manufacturing: In the hydraulic systems of injection molding machines, CNC machine tools, and other equipment, hydraulic components are connected to change the direction of hydraulic oil flow and achieve detailed action control of the equipment; In the pneumatic system of the automated production line, connect the air pipe to guide the direction of compressed air and protect the automated operation of the equipment.

Petrochemical industry: used for pipeline systems in petroleum extraction and chemical production processes, transporting petroleum, chemical raw materials, etc., requiring joints to have good corrosion resistance (based on actual reports) and high pressure resistance, confirming safe production.

Building facilities: In the water supply and drainage, fire sprinkler and other systems of buildings, changing the direction of water pipes to protect the normal operation of building water supply and fire protection systems; In the air conditioning refrigeration system, copper pipes are connected to achieve the transfer of refrigerant.

Transportation: Used in hydraulic, fuel, brake and other pipeline systems for automobiles, ships, airplanes, etc., it requires high sealing, excellent quality and safety of products to protect the normal operation and safety of transportation vehicles.
