Learn about Yuehua's 304 grade stainless steel product line

For engineering contractors, architects, and industrial plant managers, SUS 304 stainless steel specifications are a core consideration when selecting piping materials for water supply, gas transmission, fire protection, and industrial systems. Guangdong Yuehua Stainless Steel Profiles Co., Ltd., operating under the Yuehua Stainless Steel brand since 1991, manufactures a variety of pipes and fittings using 304, 304L, 316, and 316L stainless steel. This article reviews the technical specifications, manufacturing processes, and applications of Yuehua's 304 stainless steel products based on Yuehua's published production capacity data.

Company Background and Production Scale

Yuehua Stainless Steel, headquartered in Shantou, Guangdong Province, China, is a professional manufacturer and OEM/ODM supplier of stainless steel pipes , with business spanning Southeast Asia, Japan, Europe, and the United States. The company boasts a 150-mu production base with a daily capacity of 150 tons , equipped with over 170 specialized production lines , achieving vertical integration from steel rolling to finished pipe products. It is capable of achieving an annual turnover of RMB 1 billion. This scale of operation ensures the company's ability to continuously and stably supply 304 grade stainless steel pipes and fittings to large-scale infrastructure and industrial projects.

Core technical specifications of 304 grade materials

The design of Yuehua 304 grade stainless steel pipes complies with documented technical specifications:

• Operating pressure: Greater than 2.5 MPa, with the connection system incorporating high-performance sealing rings.
• Service life: Up to 70 years, making the pipes suitable for water supply, gas distribution, and fire protection pipelines.
• Material grade options: SUS 304, 304L, 316, 316L, which can be selected according to the corrosion resistance requirements of different water qualities and operating conditions.
• Production capacity: 150 tons per day,representing the available production capacity for  304 grade pipe manufacturing.

These specifications are consistent across the company's product lines, including water supply and drainage pipes, gas pipes, fire protection pipes, and plastic-coated pipes, all of which are available in SUS 304, 304L, 316, and 316L grades.

Manufacturing technology applied to 304 grade steel pipes

Yuehua's 304 stainless steel products are manufactured using a range of proprietary processes and technologies:

• Online solution treatment: Enhances material consistency and corrosion resistance during the production process.
• Thin-wall technology: This technology reduces material weight while maintaining pressure performance, and is particularly suitable for water supply/drainage piping systems.
• Dual-pressure technology: Eliminates the need for welding and threaded connections, reducing installation time and the risk of leakage at fittings compatible with 304 grade piping systems.
• Eddy current testing: Used as part of the quality inspection process.
• Pickling and passivation: Used to improve surface corrosion resistance.

These technologies are supported by a professional R&D team . Yuehua also holds over 30 national utility model and invention patents , demonstrating its continuous investment in the research and development of stainless steel pipe manufacturing processes.

Raw material procurement

Yuehua Stainless Steel Pipes (including 304 grade products) source their raw materials from POSCO , TISCO , and Yung-Chin Steel . This sourcing structure aligns with the company's established goal of ensuring consistent material quality across all its product lines.

Applications of 304 grade stainless steel products

Yuehua 304 grade stainless steel pipes are mainly divided into four product categories:

1. Water supply/drainage pipes – specifically designed for drinking water supply and drainage systems, aiming to address pain points such as secondary water contamination and high maintenance costs. Utilizing food-grade, corrosion-resistant materials, they are designed to reduce the risk of secondary water contamination in high-rise residential and commercial water supply systems, hotel infrastructure, and medical facilities.

2. Gas pipelines – specifically designed for gas delivery, corrosion-resistant, and suitable for municipal and residential gas networks. These pipelines are compatible with dual-pressure connections , enabling weld-free installation and reducing the risk of leaks.

3. Fire protection piping – suitable for fire protection systems in shopping malls, chemical industrial parks and municipal infrastructure, relying on high-performance sealing rings to withstand operating pressures exceeding 2.5 MPa.

4. Plastic-coated pipes (SUS 304, 304L, 316, 316L) – combine 304/316 grade base materials with a plastic coating to enhance corrosion resistance under specific operating conditions, suitable for water supply, gas transmission, fire protection and industrial applications.

In addition to pressure piping, Yuehua also applies 304 grade material to its industrial and decorative piping range, including round pipes for mechanical and industrial applications, as well as square and rectangular pipes for building and architectural  projects that require both structural support and aesthetics.

Connection fittings compatible with 304 grade piping systems

To complement its 304 stainless steel pipes, Yuehua manufactures four types of fittings: double-compression (clamp) fittings , ring-compression fittings , grooved clamp fittings , and welded fittings . Each type of fitting is designed to meet specific installation requirements, ranging from non-welded quick assembly to high-strength permanent connections for harsh applications. All products are compatible with water supply, gas transmission, fire protection, and industrial piping systems.

Quality Assurance and Certification

Yuehua stainless steel products, including its 304 series, have obtained multiple industry certifications such as ISO 9001 , ISO 14001 , ISO 45001 , CE , and RoHS . The company has also been awarded the titles of " China Famous Trademark" and "Guangdong Famous Trademark".

Case studies involving stainless steel piping systems

Yuehua stainless steel piping systems have been applied in numerous documented projects, including municipal infrastructure projects for Shantou University East Campus and Asian Youth Games venues, medical facility piping for the Chinese University of Hong Kong and Shantou International Eye Center, industrial application piping for food and beverage production at Jiugui Winery Co., Ltd. (Phase II), and hotel infrastructure piping for the Shantou White Swan Hotel.

Summary

For buyers researching 304 stainless steel specifications, Yuehua Stainless Steel's product data presents a consistent range of technical parameters: operating pressure exceeding 2.5 MPa, service life up to 70 years, and material options covering SUS 304, 304L, 316, and 316L. Leveraging online solution treatment, thin-wall technology, and a dual-pressure connection system, these specifications are applied to the company's water supply, gas, fire protection, and industrial product lines at its production base in Shantou, Guangdong.
