Sanitary Stainless Steel Tube

Diệp Nam Phương Sanitary Stainless Steel Tube is a product group in the field of sanitary stainless steel tube, hygienic stainless steel pipe, food-grade stainless steel tubing, pharmaceutical stainless steel tube, sanitary process piping, sanitary stainless steel pipes, food-grade stainless steel pipes, and clean fluid transfer pipes, imported, distributed, and supplied by Diệp Nam Phương Manufacturing and Trading Co., Ltd.

The product is offered with steel grades SUS 304L, SUS 316, and SUS 316L, referencing standards ASTM A270 and DIN EN 10357. The main size range is from DN10 to DN200, with various options for outer diameter, wall thickness, and surface finish. Products are sourced from Europe, Thailand, and Taiwan.

Sanitary stainless steel pipes are suitable for food processing systems, milk production, beer, beverages, purified water, pharmaceuticals, cosmetics, pure chemicals, medical equipment, and biotechnology. The relatively smooth inner surface helps limit residue buildup, facilitates pipe cleaning, and maintains fluid quality during operation.

In high-hygiene production lines, pipes directly contact raw materials during receiving, mixing, processing, transfer, and filling stages. If the inner surface is rough, has gaps, scratches, or uneven welds, materials can be retained, making cleaning difficult, increasing the risk of cross-contamination, and extending downtime.

1. Key Features

Diệp Nam Phương Sanitary Stainless Steel Tubes emphasize inner surface smoothness, weld quality, dimensional stability, and compatibility with sanitary fittings.

SUS 304L is suitable for food, water, and beverage systems under common corrosive conditions. Low carbon content helps minimize heat-affected zone issues during welding.

SUS 316 and SUS 316L are suitable for environments requiring higher corrosion resistance, especially when exposed to chemicals, salts, chlorides, or cleaning solutions. Material selection should be based on the type of fluid, temperature, pressure, and actual operating conditions.

According to company-published information, pickled and passivated pipes have an inner roughness Ra ≤ 0.8 µm. Internally polished or bright annealed types have a roughness Ra ≤ 0.6 µm. A low Ra surface helps reduce residue retention points and supports CIP or SIP cleaning processes.

The product can be connected with elbows, tees, reducers, ferrules, clamps, sanitary valves, sight glasses, pumps, and measuring devices. Clamp connections are suitable for locations requiring frequent disassembly, while welded connections are used for fixed systems. For high-requirement applications, customers may consider orbital welding to enhance weld uniformity.

2. Product Applications

Diệp Nam Phương sanitary stainless steel pipes are used in:

- Milk receiving, mixing, pasteurization, and filling systems.
- Piping for beer, beverages, syrups, and formulated solutions.
- Purified water filtration, storage, and distribution systems.
- Piping for edible oils, sauces, liquid seasonings, and food ingredients.
- Process water systems, solutions, and intermediate products in pharmaceutical plants.
- Production lines for cosmetics, functional foods, and pure chemicals.
- Medical equipment, biotechnology systems, and food processing machinery.
- Sanitary piping projects by M&E contractors and technology contractors.

The product is suitable for new production lines, capacity expansion projects, and replacement of old piping whose surface or corrosion resistance no longer meets requirements.

3. Selection and Installation

When selecting the product, customers need to determine the type of fluid, temperature, pressure, flow rate, cleaning chemicals, corrosion resistance requirements, piping standards, and connection methods.

Parameters such as steel grade, outer diameter, thickness, length, roughness, and surface finish must be checked for compatibility with fittings, valves, pumps, and equipment. ASTM A270 and DIN EN 10357 may use different size series, so the standard needs to be confirmed from the design stage.

For food, pharmaceutical, or medical projects, customers should request material documentation such as Mill Test Certificates, certificates of origin, quality certificates, and heat number information for inspection and traceability.

During installation, pipes must be stored in a clean area, separate from carbon steel. Pipe ends must be cut, cleaned, and properly aligned before connection. After welding, the joints may need heat tint removal, pickling, passivation, or polishing according to project requirements.

4. Structure and Key Parameters

The product is selected based on the following factors:

- Steel grade SUS 304L, SUS 316, or SUS 316L.
- Standard ASTM A270 or DIN EN 10357.
- Outer diameter and inner diameter.
- Pipe thickness and length.
- Inner and outer surface finish.
- Roughness Ra.
- Longitudinal weld quality.
- Compatibility with ferrules, clamps, elbows, tees, and valves.
- Quality documentation, heat number, and traceability information.

Depending on the application, customers can choose the appropriate configuration to balance hygiene requirements, corrosion resistance, durability, investment costs, and operational efficiency.

5. Benefits for Businesses

Diệp Nam Phương Sanitary Stainless Steel Tubes help businesses build piping systems with corrosion resistance, easy cleaning, and limited material retention. When combined with appropriate piping design, fittings, and welds, the product can help reduce cleaning time, limit cross-contamination, and enhance system stability.

The range of materials (SUS 304L, SUS 316, SUS 316L), sizes (DN10–DN200), and various surface options provide customers with flexibility to choose according to technical conditions and budget. Diệp Nam Phương also supplies industrial pipes, sheets, coils, stainless steel bars, pipe fittings, flanges, and valves, making it more convenient for customers to synchronize multiple material groups within the same project.

With a focus on providing comprehensive metal solutions, Diệp Nam Phương Manufacturing and Trading Co., Ltd. supports customers in selecting appropriate steel grades, standards, sizes, surface finishes, and material sources for food, beverage, pharmaceutical, cosmetic, medical, and biotechnology projects in Vietnam.
