Characteristics:
1. Good corrosion resistantance
2. Light weight and high strength
3. Easy installation
4. Smooth inner surface for good media circulation
5. Low temperature endurance, good thermal insulation
6. Lower permeability. Well-sealed joints and longer pipe length make it lower permeability than the traditional material.

Application:
Process pipe is widely used in the following industries: Petroleum, chemical, printing and dying, power, transportation, food fermentation, synthesis, water supply and sewerage, seawater refreshing, irrigation and national defense.

Main processing workmanship: Hand lay-up and filament winding

1. Hand lay-up process
We have 720 hand lay-up worker including 480 staff who have 20 years working experience in hand lay-up fabrication.
For many years, we have been devoted in the hand lay-up molding and development. Especially in hand-laid process pipe, we apply special technique and add substance in resin to reduce air bulb greatly thus increase the anti-corrosion property of the inner and sub inner liner which is a great contribution to the Chinese FRP industry. Testing results show that it is two levels better than the similar products.

2. Filament winding process
We use our international advanced winding station imported from Italy and digital-controlled winding machine developed by our own.

Technological process of pipe fabrication:
---Designing
---Equipment commission, material preparation, mold preparation
---Setting winding procedure for the microcomputer operated machine
---Liner manufacture and winding
---Whole pipe cure by distant infrared ray
---Trimming and demolding
---Hydraulic pressure testing
---Packing and storage

3. Layer construction and thickness
With our over 20 years working experience and technical communication with Italy and Germany, based on different standards such as DIN, ASTM, AWWA and others such as Japanese standards, English standards, Chinese domestic standards etc, we design the best solutions and provide material for each construction layer according to different media, pressure, temperature and condition.
