Functions of connectors

A fitting is an element that connects two pipes and is often used in piping systems. It plays a role in connecting two pipes, changing the direction of the fluid, regulating the flow of the fluid, distributing the fluid and other functions. There are many kinds of joints with different shapes, specifications and materials, but they have their own characteristics and scope of application.

I. Types of fittings

1. Elbow

Elbow can make the pipe direction change, divided into 45 degrees, 90 degrees, 180 degrees and other different angles. Elbow can be divided into SR elbow and LR elbow, SR elbow centerline length and the bend of the outer diameter of the pipe is equal to the length of the centerline of the LR elbow is 1.5 times the outer diameter of the pipe. Elbow in the piping system is the most widely used, its role is to change the direction, breaking the monotony of the piping system, increasing the plasticity of the pipeline line.

2.Tee

A tee is an element that divides a pipe into two or more pipes, which are connected to the bottom of the main pipe. It is especially common in systems where it serves to control the distribution of a fluid by diverting it from a pipe to a different component or link. There are types of tees such as T-type tee, Y-type tee and cross tee.

3. Tees

A tee is similar to a tee, but it is divided into three or more channels which are connected to the bottom of the main pipe. Its use is relatively rare, in some CNC machine tools hydraulic system and high-pressure hydraulic transmission system of some extreme working conditions, need to use a four-way, in order to divert and flow regulation.

4. Reducer

Reducer fittings can be connected to two different pipe diameters of the pipe. In the pipeline system, often need to connect different sizes of pipes together, reducer joints can well meet this requirement.

5.Flange

Flanges are components that are combined with flange gaskets, bolts and nuts to connect pipes. In some piping systems that need to be disassembled, flange connection is more applicable. Flange connections use rubber gaskets with good sealing performance. There are also many types of flanges, such as flanges (flat welding flange, butt welding flange, ring flange, enameled flange, etc.).

6. Quick coupling

Quick coupling is a kind of coupling that can quickly dismantle the pipeline connection, which can reduce time and cost. Quick coupling not only saves installation time, but also saves operation and maintenance time, making it an ideal accessory for modern and efficient piping systems.

7.Hose Fitting

A hose coupling consists of a pipe frame, a threaded connector and a metal sleeve. The pipe rack is installed at both ends of the hose and the threaded connector can be fixed on it. Hose couplings are characterized by elasticity and ease of installation, so they are used more often for connecting hoses and suction pipes.

8.Pressure pipe flange joints

In the utility industry, the hydraulic system, usually need to fasten bolts to fasten the connection interface connecting the movable switch, valve cover, connecting the two sections of the hook, columns and plates, and so on. At this time, compression piping flange joints are well suited for connecting tight piping links, such as forging, pressure machining and cold press IOT to support pressure water pipes.

9.Quick Connecting Nail Fitting

Quick Connecting Shot Nail Fitting is a new type of pipe fitting used for pressure fluid pipeline, which is simple in structure and easy to use, and then the shot nails are put into the pipe to realize the quick connection, which greatly accelerates the efficiency of on-site installation.

10.Buckle joint

Buckle fittings are widely used in ultraviolet bacterial disinfection, Rini series of standard cartridges, filter control dragon and other ultrapure water systems, is a medium-heavy and ultra-heavy hydraulic system is an important component for connecting the pipeline, can replace the brass or steel head joint products.

Second, the performance of the joint

1.Reliability

Joint is one of the important components of the pipeline, its quality will directly affect the safe operation of the pipeline system. Therefore, the installation quality of joints is an important condition to guarantee the synchronous operation of pipeline system. Joints must ensure that the vibration of the material, shall not cause loss of control phenomenon, to ensure the safe operation of the pipeline system.

2. Corrosion resistance

Joints should have the ability to resist acid and alkali, corrosion. Usually involves the chemical industry, acid pile, lye and other channels, do not damage due to chemical reaction, joints applicable liquid grease components have chemical properties, the preoperative must be put through the surface treatment, greatly improving the environmental adaptability of the joints.

3.Material selection

Joint material selection and piping system is closely related to the use of the environment. Such as in the high-temperature environment, heat-resistant alloy materials should be used; in a strong corrosive environment, corrosion-resistant materials should be used. In addition, the price of the material, processing performance, weldability and other factors also have an impact on the use of joints.

4. Environmental protection

With the growing popularity of the concept of environmental protection, the importance of the characteristics of environmentally friendly materials, has become a social responsibility. Joints should use environmentally friendly materials, in the production stage requires materials with low pollution, low odor, low toxicity, in line with environmental standards.

5. Easy to install
