Brief Introduction: |
Comparison and stability under the premise of reasonable as the weight of a light weight, high strength, corrosion resistance of non metal pipe. It is a resin based glass fiber according to process requirements of layer by layer is wound on the rotating mandrel, and the fiber distance between evenly Kamiishi Eisa layered the wall structure is advanced, can charge distribution of volatile material, to meet the use intensity and improve the steel, ensure the product reliability. Glass reinforced plastic mortar pipe with its excellent resistance to chemical corrosion, light weight, high strength, no fouling, seismic, and ordinary steel pipe service life long, the cost low, the installation is quick, safe and reliable advantages, by the majority of users.
Applicable scope: acid, alkali neutralization, water, wastewater, waste gas, flue gas, dust etc.
Applicable industries: petroleum, chemical and water drainage, electronic components production, battery production, pickling, metallurgy, chemical, pharmaceutical, coating, light industry, rubber, ships, oil, paint, brewing and other industries gas-liquid transport

| FRP round tube / square tube |
1、Molding method
Pipe production is to use Filament Winding method to finalize the design
2、Length of pipe
Round tube and square tube, standard setting unit according to the length of 6 meters.
Need to produce the length of the pipeline is not up to the standard form of the unit length, with one of the production, to be approved in advance and then produced.
Unable to use the Winding Filament method to form a square road, elbow, auxiliary pipe and flange type and other hand paste molding method.
3、Thickness
The thickness of the tube, long watch made of round pipe diameter is calculated.
In addition, considering the use of pressure and wind pressure, production according to the following standards.

4、Strengthening of pipes
（1）Circular pipe diameter less than 1600mm of the case, do not need to do additional strengthening.
（2）Circular diameter larger than 1600mm by 3M, spacing, square duct according to within 1m spacing with semi circular reinforcing ribs, according to the HALF-ROUND STIFFNER must outside the pipe with strengthening and reinforcement. But in reinforcement position connecting flange of, do not need to also add solid.
（3）The reinforcement of the provisions follows the following table of standards.

(4)Joint method and pipe length Reinforcement Standard
Joint method and pipe length reinforcement standard as shown below
|
| Elbow |
Elbow is used in front of that, using image and filament winding process for the production of pipeline mitered (Mitered) (elbow) with the method of hand Lay-up use model (mold), produced by the curve (sweep) image of elbow, with the two molding.
2、Thickness
And the same specifications of the thickness of the pipe production.
3、Specifications
Standard bend radius of curvature, and pipe diameter of 1 times R=1D count, when installing the necessary conditions on the scene with a diameter of 1.5 times (R=1.5D) is possible, made by integral forming principle and making MITER with more than five blocks (fragments) forming to reduce the flow resistance.
4、Miter bend installation
(1)The installation of the elbow is made with a Butt joint, and the joint width is standard in the following form
(2)The thickness of the bonding layer is the same as the thickness of the pipe line
(3)The inner and outer layers are laminated at the time of engagement, and the thickness of the inner layer is 2.6mm~3mm, and the thickness of the outer layer is removed.
(4) The inner and outer parts of the stack should be treated with Mat Surface (#30) surface felt for surface treatment.

| Reducer |
1、Setting method
The diameter setting method making use of Hand Lay-up.
2、Variable thickness
Diameter and large size of the thickness of the pipe production.
3、Variable specifications
（1）The adjustable length is more than 2.5 times the diameter difference[ L = ( D2 - D1 ) × 2.5 ]。
And, connecting horizontal pipe with an eccentric reducer, a vertical pipe connection, in concentric reducer production.
（2）Connect with Slip Collar, reducing the length of the body to extend the expansion length (Extension Length),Adjustable engaging flange and Butt do not need to extend the expansion length (Extension Length).
（But, if the site conditions when the diameter and the length of instructions are not reasonable, to get the approval of post production）
（3）Reducing the length of the body length and expansion molding.
（4）Subdivision items are put forward on the approved drawings.
4、Error reducing allowed
And elbow to allow the uniform application of the error.

| TEE |
1、Setting method
Three way of making hand paste shaping method（Hand Lay-up）。
2、Three pass thickness
And the same thickness of the thickness of the pipe production.
3、Three pass specifications
The three is composed of the same type of multi branch and multi branch pipe shaped, square tube.
4、Three way classification: three links, oblique insertion three links, three different diameter
