China Insulation Pipe Petroleum Pipe Polyethylene Pipe

Galvanized Pipe Insulation Jacket Manufacture

Structure
1. Steelservice pipe
2. Polyurethane rigid foam insulation
3. Hot- dip galvanizing steel casing pipeProduction range:DN25~DN1600mm
Application range:
Product application:Heating supply,cooling supply,Anti-corrosive in the field of crude oil transportation,Thermal insulation pipeline engineering
Medium temperature:≤120ºC(accidental peak<140ºC).
Medium pressure:≤2.5MPa.
Laying mode:It is mainly used for overhead laying and overhead laying of integrated pipe gallery.Standard:GB/T 29047-2012Product advantages:

1,The prefabricated overhead type metal protective layer polyurethane insulation pipe is the preferred product of the comprehensive pipe corridor and the overhead laying, whichis convenient and fast to install.
2,The metal protective layer can be made of galvanized iron coating, stainless steel, aluminum strip and other different materials, and has strong corrosion resistance and mechanical strength.
3,The polyurethane insulation layer is made of polyurethane raw material with combustion property B1 (refractory). Its high fire resistance solves the hidden danger of safety in the laying of integrated pipe gallery, and its heat preservation performance is advantageous. Long-term operation can save a lot of energy and significantly reduce energy cost.
4, Xingbang Company is currently the first production line overheadpolyurethaneinsulation pipein domestic, and the process technology and the forming equipment are independently developed by our company, and two of the national patents have been obtained.
5,Has extremely strong water-proof and corrosion-resistant capability, and can not cause the overall impact of the overhead pipe as a whole due to rain and snow and other severe environments.Comparison tablebetweenPE outer protection insulation pipeand galvanized outer protection insulationpipeitem

Laying modeIt is only suitable for buried underground, not for overhead.It is the preferred professional pipeline for integrated pipe gallery and overhead laying.trinityIt is necessary to improve the surface roughness of the inner wall by corona treatment to ensure the trinity structure.The spiral coil forming process is used to ensure the trinity structure by increasing the thread surface of the inner wall and the adhesion of the polyurethane insulation layer.ultraviolet resistanceNot resistant to ultraviolet liWoodworking Machinery ght, resulting in oxidative degradation of plastic molecules, easy to crack or even collapse, so that the insulation tube lost its working capacity.Resistant to strong sunlight exposure without corrosion, used at all kinds of altitude, the external protection pipe is not damaged, can fully protect the normal work of the heat preservation pipe.Corrosion resistanceCorrosion resistance in underground and not corrosion resistance in overhead.Thegalvanizedtubewith≥275g/m2zinclayerthicknessandstrongcorrosionresistancethroughnozincflowerandpassivationtreatment,whichcanprovideanodicprotectionandanticorrosionelectrochemicalcorrosion.
Service lifeOverhead laying is used for a maximum of 3 years.Aerial laying can reach 30 ~ 50 years, and the correct selection of galvanized sheet and processing mode can also be increased.Low temperature resistanceNot resistant to low temperature, easy to crack at-20 ºC.Under low temperature condition, its performance does not change fundamentally, still has good corrosion resistance, mechanical and impact resistance, and the low temperature is free of crack.High temperature resistanceThe maximum temperature resistance is 50 ºC, otherwise it is easy to soften, fall off and deform, and the mechanical properties are completely lost.High temperature will not deform, will not produce thermal stressandwill not reduce mechanical propertiesFire Control .itcan withstand 50 ºC and more high temperature working environment, but can be used normally, and ensure a variety of performance parameters.Impact resistanceIn the event of external force and hard object impact, easy to crack and damage.The pipe body has high strength, good toughness, strong pressure resistance, strong impact resistance, which has more ability and safety than the hard object of the anti-prying door, so it is difficult to pierce or penetrate.cost advantageMaterial cost: the external protective pipe of galvanized steel plate is used instead of pe pipe. On the material, the unit price of galvanized steel plate is 30% and 50% of that of pe material. Material dosage: because pe tube needs a certain thickness to achieve the required protective performance, so the amount of pe material is large, and the hardness and mechanical strength of galvanized steel plate itself make it achieve the same protection effect without thicker, and the dosage can be reduced by about 40% -50%.
Processing cost: the extrusion process of pe is carried out by melting, molding and cooling, and the power consumption is large, while the galvanized coil can only be combined into a circular tube with a good steel plate screw, and the energy consumption is very low.

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

5: Can I custElectric Motor omize some other sizes of products?

Yes! WCable Tools e can according to the customer's request.
