Corrosion Resistant PPR Pipe mu Chemical Pipeline System

Mukugadzirwa kwemazuva ano kwemaindasitiri, kugadzikana, chengetedzo uye kuchengetedzwa kwezvakatipoteredza kwepombi system inokanganisa zvakananga kugadzirwa kwakanaka uye mutengo wekushandisa. Advanced maindasitiri giredhi PPR mapaipi (polypropylene random copolymer pombi), maererano nenhamba, mwero wekushandiswa kwePPR mapaipi mumunda weindasitiri wakawedzera nekupfuura 45% kare 5 makore, kunyanya mumakemikari, chikafu nechinwiwa, zvemishonga nemamwe maindasitiri.

Chekutanga, Tiye akakosha mabhenefiti eindasitiri PPR pombi

1. Kemikari corrosion resistance

PPR mapaipi ane kushivirira kwakanaka kune yakasimba acids (zvakadai se sulfuric acid, hydrochloric acid), alkalis yakasimba (zvakadai sodium hydroxide) uye organic solvents, uye pH kukosha inogona kusvika 2-12, inodarika nekure muganhu wekupokana kwePVC pombi (pH 5-9).

2 Kupisa kwepamusoro uye kushanda kwepamusoro

Temperature resistance range: kwenguva refu kushanda tembiricha kusvika 95 ℃, pakarepo tembiricha kuramba kusvika 110 ℃, kusangana nekutenderera kwemaindasitiri kwemvura inopisa, steam condensate uye mamwe maficha ekupisa.

Kudzvinyirira simba: Industrial PPR pombi (zvakadai sePN25 series) kushanda kumanikidza kusvika ku2.5MPa, kuputika kudzvinyirira kweanopfuura 6MPa, inokodzera kutakurwa kwemvura yakakwira.

3. Zero kusvibiswa uye kuchengetedza chikafu

Kuburikidza neFDA, NSF, 3-A uye zvimwe zvitupa zvepasirese, zvinoenderana nezviyero zvegiredhi rekudya (zvakadai seEC 1935/2004), kubvisa njodzi yekunaya kweheavy metal.

4. Hupenyu huzere kutenderera mutengo mukana

Mutengo wekuisa ndiwo 60% yakaderera kupfuura pombi yesimbi isina tsvina, uye mari yekuchengetedza inoderedzwa ne 40%;

Hupenyu hwekugadzira hwe 50 makore, yakakwirira zvikuru kupfuura pombi yesimbi 15-20 makore.

Chepiri, iyo kupatsanura kushandiswa kwePPR pombi mumaindasitiri maficha

2.1 Makemikari uye maindasitiri emishonga

Pickling uye electroplating kugadzira mutsara

Mamiriro ekushandisa: Kuendesa kusungwa ≤30% sulfuric acid, hydrochloric acid uye zvimwe zvinoparadza media.

Technical scheme: PPR-H (enhanced) pipeline, kukora kwemadziro kwakawedzera ne 20%, ine flange yekubatanidza kuti ive nechokwadi chekusimba.

Nyaya yedata: Mushure meGerman electroplating fekitori yakachinjirwa kune PPR mapaipi, mari yekuchengetedza yegore negore yakaderedzwa kubva 120,000 euro kuti 23,000 euros.

Solvent delivery system

Kushivirira list: ethanol, acetone, xylene uye mamwe organic solvents (concentration ≤50%);

Safety design: Anti-static coating inowedzerwa kune yekunze layer yepombi, uye kupikisa kwepamusoro kwakaderera pane 10 ^ 6Ω kudzivirira static kuunganidza.

2.2 Indasitiri yezvekudya nezvinwiwa

Zvigadzirwa zvemukaka uye mutsara wekugadzira muto

CIP yekuchenesa kuenderana: inogona kumira 85 ℃, 4% sodium hydroxide solution cycle yekuchenesa, yemukati madziro kutsvedzerera Ra≤0.2μm, kuderedza kubereka kweutachiona.

Sanitary certification: Zvinoenderana neEHEDG (European Sanitary Engineering Dhizaini Boka) mipimo, kuburikidza pasina akafa Angle welding process certification.

Kubika doro System

Kushivirira kwekushisa kwakadzika: chengetedza kusimba panguva yekuvirisa kutonhora pa -10 ° C kudzivirira brittle kuputika;

Oxygen barrier layer: kushandiswa kwezvikamu zvishanu zvekubatanidza PPR chubhu (ine EVOH oxygen barrier layer) kudzivirira oxidation kuora kwemuviri wewaini.

2.3 Indasitiri yesimba idzva nekuchengetedzwa kwezvakatipoteredza

Kutonhora system ye photovoltaic power station

Weather resistance upgrade: wedzera 2% carbon black uye UV stabilizer, Upenyu hwebasa rekunze hwakawedzerwa kusvika kupfuura 30 makore;

Maitiro ekuchengetedza magetsi: thermal conductivity inongova 0.24W /m·K, 60% kuderera kwekupisa kudarika kwesimbi chubhu.

Industrial wastewater treatment

Kusvibisa kupikisa kugadzira: pakutakura mvura yetsvina ine mafuta uye granular sludge, iyo yemukati yemadziro friction coefficient yakaderera se 0.007 kudzivirira kusvibiswa uye kuvhara;

Case kuenzanisa: Mushure mekuchenesa tsvina inoshandisa PPR pombi panzvimbo yepombi yesimbi yakakandwa, kushandiswa kwesimba kwekupomba kunoderedzwa ne 22%.

Chetatu. Industrial PPR pombi yekusarudza Guide

3.1 Kusarudzwa kwegiredhi rekumanikidza

3.2 Material Ikuvandudza Scall

PPR-Anti: wedzera nano sirivheri ion, antibacterial rate ≥99.9%, inoshandiswa mumishonga yakanatswa mvura system;

PPR-ESD: embedded conductive carbon fiber, kupikisa kwepamusoro ≤10^3Ω, yakakodzera moto uye nzvimbo inoputika;

PPR-GF: girazi fiber yakasimbiswa, kuoma kwemhete kwakawedzera 50%, inoshandiswa kugadzira mapaipi epasi pevhu.

3.3 Optimization yekubatanidza mode

Hot melt socket: yakakodzera DN20-DN110 pombi, inoda kudzora tembiricha yekunyungudika 260±5℃;

Flange kubatana: yeDN50 yakakwira kudzvanywa pombi, 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.

Chechina, Industrial PPR pipeline installation and maintenance points

4.1 Installation Specifications

Bracket spacing:

Pombi yemvura inotonhora: horizontal 1.0m, vertical 1.5m;

Hot water pipe: 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 seconds, cooling 120 seconds);

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

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

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

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

Solution: 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 Nyaya 2: Chemical plant acid fog exhaust gas treatment system

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

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

Benefits: the system life is extended to 10 makore, 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?

A: 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?

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

Q3: What is the fire rating of industrial PPR pipes?

A: 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?

A: 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?

A: 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.
