Pipeline Material

Pipe

1, Rubber lined pipeline

Description:

Rubber lined pipeline is steel or other hard material pipe with inside wearing resistant, corrosion resistant or heat resistant rubber as liner to reduce the impact or corrosion from the media by its own physical and chemical properties of rubber.

Benefit:

The benefit of energy absorption significantly increase the service life of the pipe line and this will dramatically reduce the end user’s cost

We are well equipped with fully set-up rubber lining workshop for both hot curing and cold bonding rubber lining process. We can supply pipes & spools with different liners according to your unique application and requirement. Hot curing rubber lined spool is cost-effective product with extremely high bonding strength which suits all the general application. And Premium Linatex cold bonding rubber lined pipe can give you remarkable wear resistant performance to fit your high wearing application.

For Mining application, it has Primary cyclone feed pipe line (PCFD), Secondary cyclone underflow pipe line, tailing pipe line and etc. The PCFD pipe line, as the most wearing area, is lined by 25mm Linatex Premium nature rubber to give the best performance. And the tailing pipe line uses normal nature rubber with hot bonding process as liner.

Technological Process                          

1, Blasting Treatment

Sand blasting can effectively remove rust and other defects on the substrate surface, Sand blasting can obtain better roughness on the surface of the lined substrate. Uniform distribution and controllable roughness can ensure strong adhesive force of lining

2, Glue Brushing

The base surface shall be evenly painted with Glue and several layers; Ensure that the painting is in place without omission

3, Rubber plate lining

After the residual glue is applied on the drying board, ensure that the air bubbles are not fully compacted and pasted on the drying board

4, Middle Inspection

After lining, check the items: whether it meets the requirements of the drawing, whether the overlapping edge of the rubber plate is consistent with the flow direction of the medium, check whether there is bubble delamination with a diagnostic stick, and check whether there is electric leakage

5, Autoclave vulcanization

Produce per requirements for different materials.

Full process inspection to achieve high level Quality

Following international Standard, all pipes have full inspection & test to meet customer high level requirements

2.All kinds of non – standard elbows, tees and reducing.

3.Can be prefabricated according to user requirements or customized.

PTFE-lined Composite Pipe

Product performance:

Temperature:-15℃~+80℃( highest working temperature of modified polyethylene:+105℃）
Pressure: positive pressure +2.5Mpa,negative pressure at normal temperature:75Kpa
Corrosion resistance:Teflon composite steel pipe can resist almost all chemical media(including concentrated nitric acid and aqua regia) in addition to molten metal lithium, potassium, sodium, chlorine trifluoride,OF3 under high temperature, liquid fluorine with high flow.It can work at the temperature of 230℃-250℃ for a long time.PVDF or other composite steel pipes all have a good resistance to many organic solvents like halogen, halogenated hydrocarbon, strong oxidant, boiling acid and alkali.But they are not resistant to fuming sulfuric acid, hot concentrated sulfuric acid and nitric acid, over 90 ℃ ketone, ester, amine and sulfonation agent with high temperature.

Product Characteristics:

1.High Temperature Resistance–operating temperature is 250℃
2.Low Temperature Resistance–good mechanical toughness.Even if the temperature drops to -196℃, it can also keep the elongation at 5%.
3.Corrosion Resistance–For the majority of chemicals and solvents,it shows inertia. Resistance to strong acid,strong alkali, water and all kinds of organic solvents.
4.Weather Resistance–best aging life of plastic
5.High Lubricating Property–the lowest friction coefficient in solid materials
6.Inadhesion– the minimum surface tension in solid materials, and does not adhere to any material
7.Nonhazardous–no biological toxicity

Production range:

1.nominal diameter:DN20mm—DN1200mm(Large-diameter pipe can reach 4m).
2.All kinds of non – standard elbows,tees and reducings.
3.Can be prefabricated according to user requirements

Polyurethane-lined Steel Composite Pipe

Product type-description: HDPE

Polyurethane-lined steel composite pipe takes steel pipe as matrix,lined with high wear resistant, flexible and corrosion resistant polyurethane materials,and is made by special process.

Polyurethane-lined steel composite pipe has comprehensive performance of excellent wear-resisting, acid-proof, anti-alkali, anti-scaling, radiation resistance, hydrolysis resistance, high elasticity, mechanical impact resistance etc.

Product Advantages

Excellent Wear ability :Due to a better elasticity of polyurethane lining, when subjected to the impact of medium, polyurethane is forced to compress under the action of external force.After external force disappears,polyurethane recovers.This kind of “conquering the unyielding with the yielding” greatly reduces abrasion caused by direct and intense erosion to inner wall of pipe.Its wear life is dozen of times than steel pipe.

Anti-scaling:The inner wall is smooth and transparent, and the absolute roughness of the inner wall is 0.082, which can reduce the operating expenses. Little Resistance During Operation:Unlike rubber products,there’s no swelling phenomenon in the water,so its usability will not be affected. Good Water Stability and Ageing

Resistance:Elastomer of polyurethane lining has a symmetrical molecular structure, which forms external nonpolar state.Thus the adsorption of CO32-, HCO3-, OH-  in the slurry can’t be formed.And the inner surface is smooth and has good elasticity, which prevents the adhesion of scale layer, so it has better anti- scaling performance. Good

Combination:Polyurethane lining and steel pipe have a good combination.With a unique process, the combination of pouring polyurethane elastomer and steel pipe reaches 100%.Because of unique flanging process,fall off and partial tear will not appear. Weight Light&Convenient

Installation:Because of the use of thin wall, the weight is relatively light. Many connection methods can be used in the installation: flange connection, flexible pipe joint connection, welding connection.

Main application:

Polyurethane composite steel pipe has comprehensive performance such as excellent wear resistance, acid-proof, anti-alkali, anti-scaling, radiation resistance, hydrolysis resistance, high elasticity, mechanical impact resistance etc. It can be widely used in the transport of coal ash, slag, mineral powder, aluminum liquid and slurry etc. and corrosive medium in electricity, coal, mining, building materials, chemical industry.

Power Industry: Ash handling pipe, slag pipe,grey water recycling pipe of thermal power plant. For fresh water in power plant, it is better to use polyurethane composite pipe in the transport system of ash handling and acid medium.
Coal Industry: Dense-medium separation and long distance coal conveying pipe system in coal washery.Sand backfill in coal mining.
Mining Industry: Iron ore slurry, ore concentrate, tailings transportation system; closed cycle pipe floatation system ;water and sediment transportation system.
Building Materials, Chemical Industry: Coke particles transportation in iron and steel plant; red mud transportation in aluminium manufacturer; coal dust transportation in cement plant. Transportation of corrosive acid and salt, fluid pipelines, such as pipelines in oil production, silt removal engineering, urban water supply system, and Al fluid conveying pipe. All have obvious effects.

Power Losing in Pump System:

 1) Mechanical Efficiency Loss   

2) Low Hydraulic Efficiency Design  

3) Pipeline not fitting & loss    

4) Pump System configuration  

5) Partial circulation & Flow allocation
