What does pipe fittings mean?

Pipe fittings are components used in pipeline systems to achieve multiple functions such as connection, control, change of flow direction, diversion, sealing and support. They are of various types and can be classified according to different standards, such as purpose, connection method, material and processing method.

1. Connecting pipe fittings: used to achieve the connection between pipes, including flanges, unions, pipe clamps, clamps, ferrules and throat clamps. In addition, there are tees specially used for cold-drawn welding, which are used to connect pipes and form branches.

2. Direction-changing pipe fittings: used to change the flow direction of the pipeline, such as elbows and bends, which enable the pipeline to extend in the desired direction.

3. Variable diameter pipe fittings: used to adjust the diameter size of the pipeline, including reducers, reducer elbows, branch platforms and reinforcement pipes, which allow the pipeline to smoothly transition between different diameters.

4. Diversion pipe fittings: used to increase the branching of the pipeline, mainly tees and crosses, which allow the fluid in the pipeline system to flow in multiple different directions.

What are PVDF pipe fittings?

PVDF pipe fittings, made of polyvinylidene fluoride (PVDF for short), are a high-performance fluorinated plastic. It is known for its excellent chemical resistance, high temperature resistance, weather resistance and mechanical strength. These pipe fittings can resist the erosion of a variety of chemicals, including acids, alkalis and salts, so they are widely used in pipeline systems in industries such as chemicals, environmental protection, water treatment, electronics and medicine.

Dankai PVDF pipe fittings not only have excellent physical and chemical properties, but are also easy to process and weld, making installation and maintenance more convenient. They include various types of connectors, elbows, tees, crosses and flanges, which are an indispensable part of building pipeline networks. The chemical resistance, high temperature resistance, weather resistance and mechanical strength of these pipe fittings, coupled with their processability and weldability, ensure the safe and efficient operation of the pipeline system.

What is PVDF pipe fittings made of?

PVDF pipes and fittings are made of a high-performance material called polyvinylidene fluoride (PVDF for short). This high molecular polymer has a unique chemical structure that gives it excellent physical properties. PVDF not only exhibits excellent chemical corrosion resistance, high temperature resistance, oxidation resistance and weather resistance, but also has special functions such as piezoelectricity, dielectricity and thermoelectricity.

Due to these characteristics, PVDF pipes and fittings have been widely used in many industries such as chemical, environmental protection, electronics, semiconductors and water treatment. They can maintain stable performance over a wide temperature range (from -40℃ to 150℃) and can resist corrosion from a variety of strong acids, strong alkalis and organic solvents. In addition, PVDF pipes and fittings also have excellent mechanical strength, dimensional stability and electrical properties, making them ideal high-performance pipeline solutions.

What is the model of PVDF pipe fittings?

PVDF pipe fittings are important components for connecting PVDF pipes, and their models usually correspond to the inner diameter of the pipe. Common PVDF pipe fittings include DN15, DN20, DN25, DN32, DN40, etc., all the way to DN600 or even larger specifications. The numbers of these models indicate the inner diameter of the pipe fittings in millimeters (mm). For example, DN20 means that the inner diameter of the pipe fitting is 20mm. In addition, PVDF pipe fittings have different connection methods, such as hot melt connection, socket connection, flange connection, etc. Therefore, when choosing PVDF pipe fittings, in addition to considering the inner diameter, it is also necessary to select the appropriate model according to the specific application scenario and connection method. At the same time, it is also necessary to pay attention to the material, wall thickness, pressure level and other parameters of the pipe fittings to ensure the safe and stable operation of the pipeline system.
