30491 High H Series

The 30491 raised H-type series products belong to pipe fittings and related accessories, commonly used in various fluid transmission systems. The following is a detailed introduction:

Product Usage

This series of products is mainly used to achieve connection and steering between different pipelines, fittings or equipment, playing an important role in fluid transmission systems such as hydraulic, pneumatic, water supply and drainage. By connecting with hoses and hard pipes, it protects the stable transmission of fluids such as hydraulic oil, water, and gas, especially suitable for working conditions that require increasing connection height and changing pipeline direction.

Material characteristics

Usually made of materials such as stainless steel and carbon steel. Stainless steel material has excellent corrosiveness and can be used for a long time in harsh environments with humidity and chemical media without being corroded. It is suitable for industries such as chemical and food processing that require high corrosion resistance (based on actual reports); After appropriate heat treatment (such as quenching and tempering) and surface treatment (such as galvanizing and chrome plating), carbon steel material not only has high strength and hardness, can withstand high pressure, but also enhances rust prevention ability, and is widely used in industrial manufacturing, construction machinery and other industries.

structural design

Threaded connection part: adopting standard thread design, common ones include British thread (such as G thread), American thread (such as NPT thread), etc., which can tightly fit with fittings with internal threads, confirming the sealing and firmness of the connection. The threads are processed with appropriate precision, with standard tooth profiles and fine pitch. Some products also undergo special surface treatment on the threads to enhance performance and rust resistance.

Elevated and bent structure: The "elevated H-shaped" design increases the connection height, which can be flexibly applied in scenarios with limited space or requiring specific height connections; The angles of the elbow section are diverse, commonly including 90 °, 45 °, etc., which can meet different pipeline turning 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 and minimize energy loss; The outer wall has sufficient thickness and strength to withstand fluid pressure and external forces.

Easy to install structure: It is equipped with a structure that is easy to install and operate, such as a hexagonal nut, which facilitates the use of tools such as wrenches for installation and disassembly. This not only improves construction efficiency, but also protects the joints from uniform stress during installation, avoiding damage.

performance parameters

Work pressure: The range of work pressure varies depending on the material, specifications, and structure. 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, meeting the requirements for pressure bearing capacity under different working conditions.

Applicable temperature range: The temperature range for conventional products is generally around -20 ℃ -100 ℃. For products manufactured with special materials and processes, the applicable temperature range can be expanded to -40 ℃ -150 ℃ to adapt to different working environment temperatures.

Pipe diameter adaptation: With multiple specifications, it can adapt to pipes with different inner and outer diameters. The adaptable pipe diameter ranges from small diameters (a few millimeters, suitable for fluid transmission in fine instruments) to large diameters (tens of millimeters, suitable for industrial large-scale pipeline systems), meeting diverse pipeline connection needs.

Application scenarios

Industrial manufacturing: In the hydraulic systems of injection molding machines, die-casting machines, and other equipment, hydraulic components are connected to achieve stable transmission of hydraulic oil and pipeline steering, protecting the normal operation of equipment; In the pneumatic system of automated production lines, connecting air pipes guides the direction of compressed air to meet the requirements of equipment automation operation.

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

Building facilities: In the building's water supply and drainage system and fire sprinkler system, changing the direction of water pipes to protect the normal operation of the building's water supply and fire protection system; 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.
