Product Details

Glass fiber reinforced plastic process tube

1.1. Product Introduction

Glass fiber reinforced plastic process pipe is relative to glass fiber reinforced plastic sand pipe, also known as pure glass fiber reinforced plastic pipe. It is composed of pure glass fiber structure without sand structure, so it has higher strength, lighter weight, higher pressure resistance and better corrosion resistance. Generally used for small diameter high pressure pipelines, it is widely used in the petrochemical industry, especially in the field of high pressure pipelines.
