China Insulation Pipe Petroleum Pipe Polyethylene Pipe

Introduction of Pre-insulated Pipe
Pre-insulated pipe is consist of steel pipe for transmission medium, polyurethane rigid foam insulation layer and HDPE outer protection pipe.Series of pre-insulated pipe are available in our factory, we can provide DN12-DN2000mm, all kinds of diameters and insulation thickness of the pipe and the corresponding pipe fittings are available (elbow, tee, reducer, fixed bracket and so on)Work Enviroment
Pre-insulated pipe is suitable for pipeline system that with less than 120 degree medium, the peak by accident is less than 140 degree, and operating pressure is not greater than 2.5 Mpa.Carry standard
Pre-insulated pipe carry out the national standard GB/T29047-2012, ministry of construction standard CJ/T114-2000,CJ/T155-2001, reference to European EN253 (pipeline) ,EN448 (pipe fitting) standards.Production technic
In order to ensure the trinity of pre-insulated pipe structure as a whole, we make the shot blasting for the outer of the steel pipe and corona surface treatment for the plastic outer protecting pipe before foaming, derustinggradeis up to the SA2.5 of the GB/T8923-1998, the surface tension of outer protection pipe has reached 50 dyne/cm.We adopts hydraulic adjustable tilt angle injections or use the special-purpose metering pump of high pressure and large flux of vertical injections, ensure uniform foam, improve the quality of the insulation layer.Material source
Polyethylene outer protection pipe is made of high-quality high density polyethylene material, with high mechanical strength and good corrosion resistance.Polyethylene resin material: Shanghai Jin Fei HHMTR480AT, Qilu petrochemical DGDB2480, Tianjin zhongsha petrochemical PNPipe & Tube System 049 (level 100).The polyurethane insulation layer with good mechanical properties, according to customers' requirement, we can provide cfc-free water environmental protection insulation pipe, its low thermal conductivity, small heat loss, high mechanical performance and long-term heat resistance, on one side improve the environment and on the other side improve the product performance and quality.Material of polyurethane: Jinling bayer 44 v20 22 hk84c1013; Basf M20S.
Working steel pipe: not more than DN150, we adopt the 20# seamless steel pipe, more thanWire Mesh DN200, we adopt Q235B spiral steel pipe.Product information

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 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 dUniversal Medical Implement istance 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.
