China Insulation Pipe Petroleum Pipe Polyethylene Pipe

Structure

1. Plastic Service pipe
2. Polyurethane foamed-plastics
3. Polyethylene casing pipeSize: Customization according to customer requirements Service pipe

The working pipe is polypropylene(PP-R)The working pipe is chlorinated polyvinyl chloride(PVC-C)The working pipe is heat resistant polyethylene(PE-RT)Application rangeThe thermal insulation pipe is practical for domestic hot water delivery system with working pressure no higher than 1.0mpaInsulation pipe is used in domestic hot water transportation system whose working temperature is not higher than 100 ºC.The working temperatureRefrigerator, Freezer & Parts of PP-R working tube is not higher than 80 ºC, and the maximum working temperature is not higher than 90 ºC.The working temperature of PVC-C working tube is not higher than 70 ºC, and the maximum working temperature is not higher than 80 ºC.The working temperature of PE-RT working tube is not higher than 80 ºC, and the maximum working temperature is not higher than 90 ºC.Laying mode: mainly used for direct buried, can be used for overhead pipelines.

GB/T 18993.2-2003
GB/T 28799.2-2012 Product advantages In the heat preservation pipe industry, plastic instead of steel has become a reality in the field of heating secondary pipe network transportation. Long service life
Under the normal operation conditions, the service life of the pipeline can reach 50 years, which is more than three times of the service life of the steel pipe.Heat preservation performanceCustomized Service for Electronics advantage
The thermal conductivityis only 1/300 of the steel pVentilation Equipment ipe, and the heat-insulating and cold-keeping effect is good; the heat-insulating layer adopts a rigid polyurethane foaming material, and has the characteristics of high closed porosity, good thermal insulation performance, low water absorption and the like, and is an energy-saving novel product with excellent heat preservation performance, and is particularly suitable for a heating system in the north. And has automatic thermal compensation function to realize real no-compensation.Excellent corrosion resistance
With the exception of a few oxidants, it can withstand the erosion of a variety of chemical media.And has good acid and alkali resistance, can be suitable for heating, cooling, water supply and drainage and other working conditionsEasy and fast installation
Available hot melt or electric melting connection.It still works quickly in a narrow space.The joint surface is melted with the pipe, safe and free of leakage, the strength is higher than the body, and the life is the same as that of the pipe.Short construction period and low cost.
It can be buried underground directly.the excavation area is small.the overall weight of the pipe is light, which is only 1 /8 of the steel pipe, which is convenient for transportation and lower freight, and can be pre-assembled to speed up the construction progress, greatly shorten the construction cycle and reduce the comprehensive cost.
Small hydraulic loss and high thermal efficiency
The inner wall is smooth, no scaling, and the roughness is only 1/70 of the steel pipe.It makes the fluid have good liquidity and large flow rate, the hydraulic loss is very small, and the heat transfer efficiency is higher.Resistance to low temperature impact, resistance to freezing cracking
With excellent low-temperature resistance, it will not freeze at 30-40ºC. It can maintain excellent impact resistance. It completely solves the problem of low temperature brittleness of cold and hot water transmission pipelines and greatly reduces the later maintenance cost.Very high stress cracking resistance
The pipeline is flexible and elastic, will not be brittle because of stress, excellent scratch resistance, has the ability to resist the damage of the external environment, and ensures the safety of the pipeline in the whole life cycle.Environment-friendly and energy-saving
Recyclable, energy saving and environmental protection, low energy consumption in the production process of plastic materials, is environmentally friendly material; pipe life is long, three times as much as steel pipe, can reduce repeated excavation, repeated replacement of pipelines, reduce carbon emissionsEnvironment beautification and urban planning
Pipe buried directly in underground without hot (cold) pollution, nor affect the beautification and design planning of the ground environment, is the best choice for the construction of modern cities and towns, the beautification of the city and the apartment environment of the community

FAQ:

1: Are you a manufacturer or a trading company?

We are a manufacturer which hasmore than20 years' history.

2: Where is your manufacturer? How to visit it?

Our factory located inYutian Economic Development Zone ,TangShan ,China.about 1.5 hours drive time to Beijing and TianJin airport .Mainly producing pre-insulated pipes,HDPE outer protection pipe and 3PE anti-corrosive pipe.

You can take a plane to Beijing or Tianjin.then we could pick up you at Fastener & Fitting the airport .

3: How do we control our products' quality?

We have professional quality control workers and quality inspectioncenter(CNAS lab)to control the entireproduction quality.

4: How do you transport these products?

We use straps to hoist pre-insulated pipes, it can avoid no damage to our products, no hooks for lifting pipedirectly. During the handling process, collision, tossing and more ground drag scrolling are strictly forbidden.

In the process of long distance transport, the pipes should be fixed, and not damage outer protecting pipesand insulating layers.

5: Can I customize some other sizes of products?

Yes! We can according to the customer's request.
If you have any other questions, please don't hesitate, contact us.6:Can we get a sample? how topay?
Small size,the sample is free,and you just pay for the freight.
large-sized or custEtching Machine omed, it is necessary to pay the sample fee and the freight.
