GRP/FRP Flange Description

 

1. Design of GRP/FRP flanges

The existing metal or GRP/FRP molds below DN for FRP flanges are integrally formed with FRP raw materials on the mold by manual layering.

 

2. FRP Flange Standards

The production, inspection, and acceptance of our company's GRP/FRP flanges are by ASTM "Glass Steel Pipe and Fittings" standards. GRP/FRP flange connection size standards are by ASME B16.5-, ANSI B16.5-, JIS, and other standards, or designed and manufactured by our company according to customer requirements. The existing molds are DN25-DN.

 

3. FRP Flange Parameters

We have different types of flanges, such as bushing, short pipe flanges, and bushing according to different standards.

If you have any questions about product parameters, you can contact us at any time!

4. FRP Flange Forming Process

GRP/FRP flange is divided into two integral and bonding flanges according to the forming process
1. Overall flange: The overall flange is generally equal wall thick plate flange. The advantage of this structure is that the flange ring and cylinder are formed together. The reinforced fiberglass and fabric are continuous, giving full play to the characteristics of high FRP strength and ease to form. The broad flange is wholly done entirely by hand-paste.
2. Adhesive flange: The bonding flange is made by processing the flange ring and the flange pipe separately and then bonding the two together. This structure is widely used. It gives full play to the advantages of easy to-form, simple mold, easy to manufacture, suitable for manufacturing large diameter, small-batch, and different types of fiberglass flanges. When the bonding flange is made, feed the pre-processed pipe, make wool at both ends, insert it on the mold seat instead of the core shaft, and process the flange ring.

 

5. Features and use of GRP/FRP flange parts

1. GRP/FRP flange has excellent physical performance, the specific proportion of GRP/FRP pipe is 1.8-2.1, about 1/4 of steel, of the specific strength is higher than steel, cast steel, and plastic, the weight is generally not more significant than that of the same steel pipe, excellent physical and mechanical performance, in addition, the expansion coefficient of steel, heat conduction coefficient is only 0.5% of steel, is an excellent thermal and electric insulator.

2. Chemical corrosion resistance and long service life, suitable for the delivery of various media such as acids, bases, salts, and organic solvents.

3. Excellent hydromechanical characteristics. Hydraulic characteristics are one of the essential characteristics of GRP/FRP pipes. Excellent hydraulic characteristics mean that the fluid pressure head loss is slight, and the transmission pump with a small pipe diameter or small power can be selected to reduce the initial investment of the pipeline engineering, save electric energy and reduce the operation cost. The inner surface of FRP is relatively smooth, and the general surface roughness rate can be 0.008, which can almost be considered as a "hydromechanical smooth pipe." In operation, the inner surface of steel pipe, cast iron pipe, and cement pipe often produces local corrosion and becomes rougher and worse. Fiberglass always maintains the smooth surface of the new pipe.

4. Installation and maintenance cost is low. In general, GRP/FRP pipe does not need special corrosion treatment; the insulation layer can be thinner or even without insulation treatment; light pipe, lifting equipment tonnage, less power consumption, GRP/FRP pipe length is longer than cement pipe and cast-iron pipe, relatively reduced, which will reduce the installation and maintenance cost, which has been proved by many engineering practices at home and abroad.

 

What is GRP/FRP flange?

FRP stands for "fiberglass reinforced plastic." An FRP flange is a type of flange that is made from fiberglass-reinforced plastic. A flange is a type of connector or coupling that is used to join two pipes or other mechanical components together. It typically consists of a circular ring that is attached to one end of a pipe or component and has an opening on the other end that allows it to be connected to another pipe or component.

 

 

FRP flanges are often used in applications where corrosion resistance is important, as fiberglass-reinforced plastic is resistant to many corrosive chemicals. They are also lightweight and easy to install, making them a popular choice in many industries, including chemical processing, water treatment, and oil and gas. However, it is important to note that FRP flanges may not be suitable for all applications, as they may not be as strong or durable as flanges made from other materials, such as metal. It is always a good idea to consult with us to determine the best type of flange for a particular application. 

We also provide Phenolic FRP, FRP Grating, FRP Flange Cover, FRP Tee, and FRP Elbow.
