What is PVC?

Polyvinyl Chloride Referred to As PVC. PVC Plastic is Often Called "Vinyl".

Pure Polyvinyl Chloride (PVC) Resin Belongs to a Class of Strong Polar Polymers, and Its Intermolecular Force is Large, Which Leads to High Softening Temperature and Melting Temperature of PVC. Generally, It Takes 160~210℃ to Process. In Addition, The Substituted Chlorine Group Contained In The PVC Molecule Easily Leads to The Dehydrochlorination Reaction of The PVC Resin, Which Causes The Degradation Reaction of PVC, So PVC is Extremely Unstable to Heat, and The Temperature Rise Will Greatly Promote The Dehydrochlorination of PVC. The De-Hcl Reaction Begins, Which Leads to The Degradation of PVC. In View of The Above Two Deficiencies, PVC Needs to Be Added With Additives During Processing, So That Various Soft, Hard, Transparent, Good Electrical Insulation, Foaming and Other Products That Meet People's Needs Can Be Produced. When Choosing The Variety and Dosage of Additives, We Must Comprehensively Consider Various Factors, Such As Physical-Chemical Properties, Flow Properties, Molding Properties, and Finally Establish An Ideal Formula. In Addition, According to Different Uses and Processing Methods, It is Also Necessary to Choose The Type of Resin. The Combination of Different Types of PVC Resins and Various Additives is The So-Called PVC Formula Design.

What is UPVC(PVC-U) Pipe?

UPVC Pipe, Also Known as Rigid PVC Pipe, is Composed Of Amorphous Thermoplastic Vinyl Chloride Resin By Adding Certain Additives (Such as Stabilizers, Lubricants, Fillers, Modifiers, Etc.),and Then Processed Into Pipes By An Extruder.

Advantages of The UPVC Pipe

Light Weight, Corrosion Resistance, High Strength, Recyclable, etc.

Disadvantages of The UPVC Pipe

High Melt Viscosity, Poor Fluidity And Other Processing Difficulties.

Formula of The UPVC Pipe

PVC (SG-5) + Stabilizer (Lead Salt, Metal Soap) + Lubricant + Processing Aid + Pigment

What is CPVC Pipe?

CPVC Power Pipe is Usually Used as Cable Protection Pipe. The Performance Indicators Have Reached Or Exceeded The Domestic Level Of Similar Products Through National and Provincial Testing, Identification and Certification. The Product Performance is Much Better Than The Traditional Asbestos Cable Pipe and Ordinary PVC Pipe,and It is An Ideal Substitute For The Traditional Power Cable Sheath.

Scope of application

It is Widely Used In Urban Power Grid Construction And Reconstruction; Urban Municipal Reconstruction Projects; Civil Aviation Airport Engineering Construction; Engineering Park And Residential Engineering Construction;

Product Features

1. Material Properties

CPVC Power Pipes Are Mainly Made of PVC-C Resin With Excellent Heat Resistance and Insulation Properties. CPVC Products Are Recognized As Green and Environmentally Friendly Products, and Their Excellent Physical and Chemical Properties Are Increasingly Being Valued By The Industry.
CPVC Power Pipe is a Hard Straight Solid Wall Pipe, The Inner and Outer Walls Are Smooth and Flat, The Color is Orange-Red, The Color is Bright and Eye-Catching.

2. Heat Resistance

Compared With The Common Upvc Double-Wall Corrugated Pipe, The Heat-Resistant Temperature of CPVC Power Pipe is Increased By 15℃, and it Can Maintain No Deformation Under The Environment Above 93℃, and Has Sufficient Strength.

3. Insulation Performance

CPVC Power Pipes Can Withstand High Voltages of More Than 30,000 Volts.

4. Compression Resistance

After Material Modification of The CPVC Power Pipe, The Ring Stiffness of The Product Reaches 10 KPa, Which is Significantly Higher Than The Relevant State Departments For Buried Plastic Pipes, and The Ring Stiffness Should Be Above 8 KPa.

5. High Impact Strength

The CPVC Power Pipe Can Withstand The Impact Force of 1 Kg Heavy Hammer and 2 m Height At The Temperature of 0 ℃, Which Fully Reflects The Low Temperature Impact Performance of The Material, Which is Fully Applicable To The Requirements of The Construction Environment.

6. Flame Retardant Properties

Both Pvc and PVC-C Materials Have Good Flame Retardant Properties and Can Be Extinguished Immediately After Leaving The Fire. Especially PVC-C Material, Because Its Chlorine Content is Significantly Higher Than That of PVC, The Flame Retardancy and Smoke Density Index Are More Significantly Improved.

7. Installation Performance

CPVC Power Pipe is Light In Weight, High In Strength, and Simple In Construction and Laying Method, Which Can Realize Excavation and Burying At Night, Backfill The Road Surface, and Can Be Opened To Traffic During The Day. it Can Prevent The Leakage of Groundwater and Effectively Protect The Safe Use of Power Cables.

8. Long Service Life

CPVC Power Pipe Material is Corrosion-Resistant, Anti-Aging, and Has a Service Life of More Than 50 Years.

What is PVC-O Pipe?

PVC-O, Biaxially Oriented Polyvinyl Chloride, is The Latest Evolution of PVC Pipe. The Pipe is Manufactured Through a Special Orientation Process, and The PVC-U Pipe Produced By The Extrusion Method is Stretched Axially and Radially. , So That The PVC Long-Chain Molecules In The Pipe Are Regularly Arranged In The Biaxial Direction, and a New Type of PVC Pipe With High Strength, High Toughness, High Impact Resistance and Fatigue Resistance is Obtained.

The Research and Development of PVC-O Pipes Can Greatly Save Raw Material Resources, Reduce Costs, Improve Product Performance, and Have Obvious Economic and Social Benefits.

How Do I Make PVC Pipe?

PVC Pipes Are Extruded From PVC Raw Materials That Enter The Screw And Melt.
The Same Steps For a General Plastic Pipe Extrusion Operation:

·Feed Raw PVC Powder/Granules into Screw Extruder.
·Heating And Melting In Multiple Zones of The Extruder.
·Extruded Into a Tube Through a Die.
·Tube Cooling Via Vacuum Setting Box And Spray Tank.
·Cut The PVC Pipe to The Desired Length.
·However, Despite Having a Similar Manufacturing Process to Most Plastic Pipes, PVC Pipes Have Inherent Characteristics That Present Additional Challenges For Pipe Manufacturers In Terms of Production And Positioning of Their Products In The Market.
