ភាសាខ្មែរCurrently, wastewater systems with low chemical concentrations widely use plastic flanges, making them one of the most interesting plastic accessories. If you still do not know what plastic flanges are, how many types there are, and their uses, let’s find out the details of Bao Tin Steel through this article.
What is a plastic flange?
Plastic flange (plastic flange) is a type of flange made from PVC, UPVC, CPVC, PPR, PPH, HDPE,… plastic materials used to install—connect or lock pipes together, pipes with equipment, or equipment with equipment.
The English name of plastic flanges is plastic flanges.
Normally, plastic flanges are made of uPVC, HDPE, PPR, etc. to suit many pipeline systems. Depending on the production method, plastic flanges will have forms such as hollow flanges and solid flanges.
Technical specifications of plastic flanges
- Size: DN15, DN20, DN25, DN32, DN40, DN50, DN65, DN80, DN100 to DN500
- Material: uPVC, cPVC, PVC, PPR, HDPE, PPH,…
- Connection: Welding, glue
- Working temperature: Max 60 degrees C
- Origin: Vietnam, China, Korea, Taiwan,…..
- Flange standards: JIS, DIN, ANSI, BS
- Usage environment: Water, air, oil, gas,….

Advantages and disadvantages of plastic flanges
Plastic flanges are one of the important accessories in the pipeline system, they have advantages and disadvantages that need to be considered. Below are some basic strengths and weaknesses of this type of product.
Advantage
- It makes the pipeline easy to install, maintain, and replace.
- Flexible in connecting the valve and the pipeline, helping to form a complete system.
- Low cost
- Diverse materials are suitable for many different working environments.
- Prevents leakage in diverse environmental conditions.
- Anti-vibration and maintains the stability of the pipeline system during operation.
Disadvantages
Although there are many outstanding advantages, plastic flanges still have some disadvantages as follows:
- Lower pressure resistance than steel flanges or stainless steel flanges.
- Limit use in high-temperature environments.
Types of plastic flanges
PVC plastic flange
This is a flange product made of polyvinyl chloride plastic, specialized for current plastic pipes. With outstanding advantages: good chemical resistance, anti-electricity, and good self-extinguishing ability.
PVC flanges are manufactured to all standards, such as BS standard PVC flanges, JIS standard PVC flanges, ANSI standard PVC flanges, and DIN standards. Especially, there are a variety of sizes: DN15-DDN500, in which PVC plastic flanges with a diameter of 60, PVC flanges with a diameter of 90, and PVC flanges with a diameter of DN200 are popular because they are suitable for all types of projects.
There are 2 popular types of PVC flange designs today:
- PVC Blind Flange
- PVC Hollow Flange
Maybe you don’t know, but when it comes to PVC flanges, we cannot miss the following brands: Binh Minh PVC flanges, De Nhat PVC flanges, Tien Phong PVC flanges, etc.
uPVC plastic flange
uPVC flange is an abbreviation of “Unplasticized Poly Vinyl Chloride,” which is the name of another type of PVC flange made from unplasticized PVC. Currently, UPVC flanges can replace PVC. However, when using uPVC and PVC flanges in the same environmental conditions, uPVC flanges are stronger and harder than PVC flanges. Not only that, but uPVC flanges are also impact-resistant.
uPVC flanges are manufactured according to all current standards: JIS, DIN, ANSI, BS, etc., along with flange types such as uPVC hollow flanges and uPVC blind flanges.
cPVC plastic flange
cPVC plastic flange is an abbreviation of “Chlorinated Polyvinyl Chloride,” which is a thermoplastic produced by the chlorine of polyvinyl chloride. cPVC plastic flange products are more flexible and can withstand higher temperatures than standard PVC plastic.
This is a plastic flange line that improves temperature resistance, fire resistance, and mechanical strength. Therefore, cPVC plastic flange products are applied in environments with harsh temperatures and chemical properties.
Popular types of cPVC flanges today:
- cPVC Hollow Flange
- cPVC Solid Flange
Currently, cPVC flanges are manufactured in full sizes DN15-DDN600 along with current flange production standards BS, JIS, ANSI, and DIN.
PPR plastic flange
This type of flange is made from PPR plastic material (full name is High Molecular Weight Poly Propylene Random Copolymers), also known as PPR heat-resistant plastic flange. The heat resistance is 70–110 degrees Celsius, and the pressure is 10–25 bar. Because of this feature, PPR flanges are widely used and important in industry and other fields.
Some types of PPR flange sizes are popular with customers, such as the PPR DN50 flange, and the PPR DN65 flange,…
You want to buy PPR flanges but do not know which brand to choose. Please refer to the following types: Tien Phong PP flange, and Binh Minh PP flange,…
HDPE Flange
HDPE flange is a type of flange made from HDPE (High-Density Polyethylene) material, a thermoplastic made from petroleum. The high-density molecular structure makes it thick, hard, impact-resistant, and stretchable better than regular PE plastic.
PPH plastic flange
This type of flange is made from PPH material (Polypropylene Homopolymer), used to install, connect, and lock the ends of plastic pipe systems and industrial equipment systems such as plastic butterfly valves, plastic ball valves, globe valves, gate valves,… and other related systems.
PPH flanges have a simple design with many types: PPH flanges with ribs, flat, hollow, solid,…
