70011 Series-72011 Series

The 70011-72011 series products mainly include pipe fittings and related accessories, which play a key role in various fluid transmission systems. The following is a detailed introduction:

Product Usage

This series of products is mainly used to connect hoses with other fittings and equipment, or to achieve specific connection functions in pipeline systems. It is widely used in fluid transmission systems such as hydraulic, pneumatic, and fuel systems. For example, connecting hydraulic pumps, hydraulic cylinders, and hydraulic valves in hydraulic systems to confirm stable transmission of hydraulic oil and provide power for mechanical equipment; Connect air pipes and pneumatic components in pneumatic systems to ensure smooth flow of compressed air.

Material characteristics

Common materials include stainless steel, carbon steel, and copper alloys. Stainless steel products have excellent corrosiveness and can work stably in harsh environments with humidity and chemical corrosive media. They 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 and surface treatment (such as galvanizing), has high strength and good performance, and can withstand high pressure. It is commonly used in industries such as industrial manufacturing and construction machinery; Copper alloy material has good thermal conductivity, electrical conductivity, and definite corrosiveness, and is suitable for occasions with special requirements for medium purity and working temperature.

structural design

Circular connection end: Some products have a circular structure, which can be easily connected to other components through bolts, pins, etc., achieving hinge function and allowing for angular swinging. It is suitable for scenarios that require movable connections, such as hydraulic pipeline connections for robotic arms.

Threaded connection part: Adopting standard thread design, such as British thread (G thread), American thread (NPT thread), etc., it can tightly fit with fittings with internal threads, protecting the sealing and firmness of the connection. The thread has undergone excellent processing, with fine tooth shape and uniform pitch. Some products also have special surface treatment on the thread to enhance rust prevention and performance.

Sealing design: To ensure that there is no leakage during fluid transmission, the product usually has a sealing structure at the connection point, such as a sealing ring groove, which can be installed with O-rings and other sealing components to improve sealing performance.

performance parameters

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

Applicable temperature range: Conventional products are generally suitable for temperatures around -20 ℃ -100 ℃, while products manufactured with special materials and processes can be expanded to a temperature range of -40 ℃ -150 ℃, which can adapt to different working environment temperatures.

Pipe diameter adaptation: There are multiple specifications to choose from, suitable for hoses with different inner and outer diameters. Common adaptation pipe diameters range from a few millimeters (for fluid transmission in delicate instruments) to tens of millimeters (for industrial large-scale pipeline systems), meeting diverse pipeline connection needs.

Application scenarios

Industrial manufacturing: used in hydraulic systems of heavy machinery such as excavators and cranes to connect various hydraulic components and transmit power; In the pneumatic control system of an automated production line, connecting air pipes and various pneumatic actuators to achieve automated operation of the equipment.

Automotive industry: Used in the hydraulic pipelines of braking systems, fuel supply systems, and suspension systems of automobiles to ensure the excellent delivery of brake oil, fuel, and other fluids, protecting driving safety and vehicle performance.

Aerospace: In the hydraulic and fuel pipeline systems of aircraft, due to the high requirements for product quality and safety, this series of products protects the normal operation of aerospace equipment with the characteristics of appropriate precision and reliability.

Energy industry: used to connect pipelines and equipment in the process of oil and natural gas extraction and transportation, adapt to complex working conditions and harsh environments, and ensure stable energy transmission.
