Advanced industrial grade PPR pipes (tubos copolímeros aleatorios u polipropileno), according to statistics, the utilization rate of PPR pipes in the industrial field has increased by more than 45% in the past 5 ja'abo'ob, especially in the chemical, food and beverage, pharmaceutical and other industries.

Yáaxil, The core advantages of industrial PPR pipeline

1. Chemical corrosion resistance

PPR pipes have excellent tolerance to strong acids (such as sulfuric acid, hydrochloric acid), k'a'am álcalis (such as sodium hydroxide) and organic solvents, and the pH value can reach 2-12, far exceeding the corrosion resistance limit of PVC pipes (pH 5-9).

2 High temperature and high pressure performance

Temperature resistance range: long-term working temperature up to 95℃, instant temperature resistance up to 110℃, to meet the industrial circulation of hot water, steam condensate and other high temperature scenes.

Pressure capacity: Industrial PPR pipe (such as PN25 series) working pressure of up to 2.5MPa, bursting pressure of more than 6MPa, suitable for high-pressure fluid transport.

3. Zero pollution and food safety

Through FDA, NSF, 3-A and other international certifications, in line with food grade contact material standards (such as EC 1935/2004), to eliminate the risk of heavy metal precipitation.

4. Full life cycle cost advantage

The installation cost is 60% lower than the stainless steel pipe, yéetel u tojol le mantenimiento ku xu'ulul tumen 40%;

The design life of 50 ja'abo'ob, much higher than the metal pipe 15-20 ja'abo'ob.

Ka'a, the subdivision application of PPR pipeline in industrial scenes

2.1 Chemical and pharmaceutical industries

Pickling and electroplating production line

Escenario u ka'anatako'ob: Conveying concentration ≤30% sulfuric acid, hydrochloric acid and other corrosive media.

Technical scheme: PPR-H (enhanced) tubería, wall thickness increased by 20%, with flange connection to ensure tightness.

Case data: After a German electroplating factory switched to PPR pipes, the annual maintenance cost was reduced from 120,000 euros to 23,000 euros.

Solvent delivery system

Tolerance list: ethanol, acetone, xylene and other organic solvents (concentration ≤50%);

Safety design: Anti-static coating is added to the outer layer of the pipeline, and the surface resistance is less than 10^6Ω to prevent static accumulation.

2.2 Industria ti' janalbe'eno'ob yéetel uk'aj chuuk waj

Dairy products and juice production line

CIP cleaning compatibility: can withstand 85℃, 4% sodium hydroxide solution cycle cleaning, inner wall smoothness Ra≤0.2μm, reduce microbial breeding.

Sanitary certification: In line with EHEDG (European Sanitary Engineering Design Group) estándares, through no dead Angle welding process certification.

Beer brewing System

Low temperature tolerance: maintain toughness during fermenter cooling cycle at -10 ° C to avoid brittle cracking;

Oxygen barrier layer: the use of five layers of composite PPR tube (containing EVOH oxygen barrier layer) to prevent oxidation deterioration of the wine body.

2.3 New energy and environmental protection industry

Cooling system of photovoltaic power station

U ma'alo'obkíinsa'al u resistencia ti' le k'iino': ts'áaj 2% carbon black and UV stabilizer, outdoor service life extended to more than 30 ja'abo'ob;

Energy-saving characteristics: thermal conductivity is only 0.24W /m·K, 60% less heat loss than metal tube.

Industrial wastewater treatment

Pollution resistance design: when transporting oily wastewater and granular sludge, the inner wall friction coefficient is as low as 0.007 to avoid fouling and blockage;

U ke'etel le óoltaj: After a sewage treatment plant uses PPR pipe instead of cast iron pipe, the energy consumption of pumping is reduced by 22%.

Teersero. Industrial PPR pipe selection Guide

3.1 Pressure grade selection

3.2 Nu'ukulil teenmprovement Scheme

PPR-Anti: add nano silver ion, antibacterial rate ≥99.9%, used in pharmaceutical purified water system;

PPR-ESD: embedded conductive carbon fiber, surface resistance ≤10^3Ω, suitable for flammable and explosive environment;

PPR-GF: glass fiber reinforced, ring stiffness increased by 50%, used for underground buried pipelines.

3.3 Optimization of connection mode

Hot melt socket: suitable for DN20-DN110 pipeline, need to control the melting temperature 260±5℃;

Flange connection: for DN50 high pressure pipeline, it is recommended to use stainless steel reinforcement flange;

Electric fusion pipe fittings: automatic electric fusion welding is used in explosion-proof areas or narrow Spaces.

Kanp'éel, Industrial PPR pipeline installation and maintenance points

4.1 Installation Specifications

Bracket spacing:

Tubo síis ja': horizontal 1.0m, vertical 1.5m;

Tubo ja' chokoj: horizontal 0.8m, vertical 1.2m;

Thermal compensation design: set an Ω type compensator every 30 meters to absorb linear expansion (expansion coefficient 0.15mm /m·K).

4.2 Solutions to common problems

Pipe deformation: bending caused by temperature fluctuations can be corrected by adding a guide bracket;

Joint leakage: check the hot melt time (pipe diameter 20mm need to heat 5 segundos, cooling 120 segundos);

Chemical corrosion: if contact with strong oxidant (such as concentrated nitric acid), need to use PVDF material pipe.

Jo, How does PPR pipeline help enterprises reduce costs and increase efficiency?

5.1 Kaaso 1: A multinational beverage factory upgrades the production line

Pain points: the original stainless steel pipe frequently rusted, resulting in excessive microbial products;

Sóolusion: PPR-3A pipeline system is adopted, the inner wall is electrolytically polished to Ra 0.1μm;

Results: 80% reduction in line downtime and $350,000 in annual maintenance costs.

5.2 Kaaso 2: Chemical plant acid fog exhaust gas treatment system

Desafiyo: PVC pipe in 50℃ acidic environment for 2 years embrittlement rupture;

Sóolusion: Deploy PPR-H acid resistant pipe (wall thickness 6.5mm), supporting corrosion resistant flange gasket;

Ustilil: the system life is extended to 10 ja'abo'ob, and the waste gas treatment efficiency is increased by 18%.

Last, The Most Important Question of Industrial PPR Pipe

Q1: Can PPR pipeline transport 120℃ high temperature steam?

JUNTÚUL: PN20 or above specifications should be selected, and glass fiber reinforced layer should be installed, but it is recommended to switch to metal composite pipe for long-term use.

Q2: How to test the chemical resistance of PPR pipe?

JUNTÚUL: According to ISO 4437 estandáar, 28 days full immersion test is carried out to detect the weight change rate (≤5%).

P3: What is the fire rating of industrial PPR pipes?

JUNTÚUL: In line with UL94 V-2 flame retardant standard, oxygen index ≥28%, but to avoid direct burning of open flame.

Q4: Can large caliber PPR pipe (DN200) be used for underground burial?

JUNTÚUL: PPR-GF pipe with ring stiffness ≥8kN/m² should be selected, and sand cushion layer should be laid to prevent settlement.

Q5: How are PPR pipes compatible with valves?

JUNTÚUL: It is recommended to use PPR flanged ball valve or stainless steel lined PPR valve to avoid the difference between metal and plastic direct thermal expansion and contraction.
