Enamel Glass Filter Machine

Stainless steel filters are among the most common and widely used filtration devices in the industrial sector. They are highly favored for their robustness, durability, corrosion resistance, ease of cleaning and disinfection, as well as their broad range of applications.

I. Core Features and Advantages

1. Exceptional corrosion resistance

· Made from stainless steel materials such as 304, 316, and 316L, it effectively resists corrosion from water, steam, various acids, alkalis, and chemical solvents, ensuring a long service life.

· 316/316L stainless steel, thanks to the addition of molybdenum, exhibits superior resistance to chloride corrosion, making it particularly suitable for coastal environments, water with high chloride ion content, or chemical processing applications.

2. High Strength and Durability

· High mechanical strength, capable of withstanding high operating pressures and hydraulic shocks, and resistant to deformation or damage.

3. Hygienic standard, easy to clean

· The surface is smooth and seamless, making it resistant to material adhesion, and meets the hygiene standards of the food and pharmaceutical industries (such as GMP and 3-A).

· Supports CIP (Clean-In-Place) and SIP (Sterilize-In-Place), making thorough cleaning and disinfection easy with no dead corners.

4. High-Temperature and Low-Temperature Resistance

· It features a wide operating temperature range, from cryogenic to high temperatures (the specific range depends on the seal material), making it suitable for processes that require heating or high-temperature sterilization.

5. Beautiful appearance, stable structure

· It features a strong metallic texture, a clean and elegant appearance, and a robust overall structure.

II. Summary of Application Industries

Stainless steel filters, thanks to their outstanding performance, have permeated nearly every modern industrial sector.

· Food and Beverage: Filtration and sterilization of water, fruit juices, milk, alcoholic beverages, and syrups.

· Pharmaceutical and Bioengineering: Sterile filtration of pharmaceutical solutions, purified water, water for injection, and compressed air.

· Chemicals and Petrochemicals: Filtration and purification of various chemical raw materials, solvents, and catalysts.

· Electronics industry: Ultra-pure water production, precision filtration of chemicals.

· Water treatment: wastewater treatment, reclaimed water reuse, and pretreatment for seawater desalination.

· Metalworking: Purification of coolants, lubricants, and hydraulic oils.

Summary: Stainless steel filters are a high-performance, highly reliable, and hygienic filtration solution. From coarse filtration to precision sterilization, and from simple pipe protection to complex automated systems, they prove indispensable—serving as the cornerstone for ensuring product quality, safeguarding critical equipment, and elevating process standards.

Enamel Glass Filter

I. Core Definition

A glass-lined filter, commonly referred to as an enamel filter or a glass-lined filtration tank, is a type of filtration equipment made by tightly coating a metal substrate—primarily a high-quality steel base—with a glassy glaze rich in silicon, followed by high-temperature firing (around 900°C).

Simply put, it combines the strength of metal with the chemical stability of glass, making it an ideal choice for handling highly corrosive materials.

II. Key Features and Advantages

All the advantages of the enameled glass filter stem from the "glass lining" on its surface.

1. Exceptional corrosion resistance

· This is its most significant feature. It can withstand corrosion from a wide range of organic acids, inorganic acids, salts, solvents, and weak bases—excluding hydrofluoric acid, fluoride-ion-containing media, concentrated phosphoric acid, and strong alkalis (especially at high temperatures).

· Application areas: Widely used in industries such as chemical engineering, agrochemicals, pharmaceuticals, dyes, food, and metallurgy.

2. Smooth surface, resistant to sticking

· The glass glaze is smooth as a mirror, with a low coefficient of friction, making it difficult for materials to adhere to its surface—and exceptionally easy to clean.

· Advantage: This is crucial for filtering viscous materials or industries requiring high cleanliness levels (such as pharmaceuticals and food), effectively preventing cross-contamination and ensuring product purity.

3. Insulation性能

· The glass layer is a good insulator and exhibits excellent dielectric properties.

4. Certain wear resistance

· It has high hardness and exhibits excellent wear resistance, surpassing many metallic materials.

5. High cost-effectiveness

· For applications requiring both corrosion resistance and a certain level of pressure, enameled glass equipment is significantly more cost-effective than manufacturing with expensive metals such as pure stainless steel, Hastelloy, or titanium.
