GRP pipe

Introduction

GRP pipe(continuous filament winding process) is an advanced composite material pipe which is made by continuous winding process. It is made from fiberglass, unsaturated polyester resin and quartz sand. FRP pipe has not only the properties of lightweight, high strength, excellent hydraulic performance, strong designability and stable quality, its comprehensive economic and social benefits are also very significant. It has obvious advantages in many fields such as municipal construction, petrochemical industry, water conservancy and irrigation, submarine drainage, pressure water supply and sewage treatment.

Technical indicators 

Equipment characteristics

Our production lines combine modern sensing, information network, automation, artificial intelligence and other new technologies. They have the characteristics of high integration and high information. They can realize remote control and meet the intelligent manufacturing requirements advocated by the government.

Process characteristics

The GRP pipe realizes continuous and rapid prototyping of pipes in a layer-by-layer stacking manner.

Structural features

The wall of the GRP pipe adopts two reinforced methods of hoop continuous fibers and three-dimensionally distributed chopped fibers. The pipe wall is connected into a whole by the chopped fibers, which overcomes the defects of the laminated structure.

Performance characteristics

GRP pipe not only has the hydraulic properties and anti-corrosion properties of plastic pipes, but also has the mechanical properties of metal pipes.

1. Basic Features

（1）Light weight and high strength

（2）Excellent hydraulic characteristics

（3）Corrosion preventive

2.Core Features

The three-dimensional reinforced pipe wall structure improves the flexibility and bending strength

（1）The GRP pipe is strong in radial deformation, and the pipe wall structure is not easy to be damaged when a large radial deformation occurs.

（2）The bending strength of GRP pipe is high, and the pipe can withstand the high combined stress caused by internal pressure and external pressure.

Product connection mode

1、Flexible connection

Flexible connection is the main connection mode of continuous wound fiber glass reinforced plastics pipe, which is connected by sleeve joint that is made of integral rubber sealing ring.

2、Rigid connection

Rigid connection is the auxiliary connection mode of continuous wound fiberglass reinforced plastics pipe, and the rigid connection mode mainly includes flange connection and flat end docking.
