How to Ensure the Precision Manufacturing Process and Quality Control of PTFE 304/316 Stainless Steel Braided Hose

As a manufacturer committed to producing high-quality PTFE 304/316 stainless steel braided hoses, we understand the high expectations our customers in the U.S. and Europe have regarding product quality. These markets demand exceptional durability, stability, and safety from their products. To ensure that every hose meets or exceeds these requirements, we implement strict quality control measures throughout our production process, guaranteeing outstanding performance in every hose.

Here are the key steps in our quality assurance process:

1. Premium Raw Materials – Sourced from World-Class Suppliers

All of our PTFE raw materials come from globally recognized suppliers: Japan's Daikin and America's Chemours. To ensure long-term stability, high temperature resistance, and corrosion resistance, we only use 100% pure PTFE. As industry leaders, Daikin and Chemours provide raw materials that meet the highest standards, ensuring that every braided hose starts with a solid and reliable foundation.

2. Precise Mixing – Expert Craftsmanship

During the manufacturing process, our experienced technicians carefully blend PTFE resin with oils in strict, precise proportions based on years of accumulated expertise. Each batch of raw materials is rigorously monitored to ensure that the final mixture guarantees consistency in the product’s quality and stable performance.

3. Precision Dimension Testing – Ensuring Customer Specifications

After extrusion by our 28 extruding machines, every hose undergoes precise measurements of both internal and external diameters. We use high-precision inspection equipment to ensure that every hose’s dimensions are in strict accordance with customer specifications and international standards. Whether it’s tolerance range or diameter size, we maintain strict control to ensure no deviations.

4. Wall Inspection Under Strong Light – Ensuring No Contaminants

Once the dimensional testing is complete, each hose is carefully inspected under strong lighting. This step allows us to detect any microscopic contaminants or air bubbles within the hose wall, ensuring that the inside and outside surfaces are smooth and free of defects. This additional inspection step is an extra safeguard to prevent potential hidden issues.

5. Precise 304/316 Stainless Steel Braiding – Enhancing Durability and Pressure Resistance

Through high-quality stainless steel braiding (304 or 316 grade), we further enhance the strength and corrosion resistance of the hose. 304 and 316 stainless steel are widely used in high-end industrial applications due to their excellent resistance to oxidation and corrosion, making them perfect for harsh working environments. Our braiding process is intricate and precise, ensuring that each hose’s braided layer is uniform and tightly woven, preventing any unraveling or rupture due to external forces.

6. High Pressure Leak Test and Sparkle Test – Ensuring Safe Performance

Next, each hose undergoes a high-pressure leak test and sparkle test. These tests simulate extreme conditions the hose may face during use, ensuring the hose maintains its airtightness and avoids leaks under high-pressure environments. This step guarantees the safety and reliability of the hose over its lifespan.

7. High-Pressure Hydrostatic Test, Bending Resistance High and Low Temperature and Tensile test(SAE J30), Electrical breakdown test(SAE J30), Medium High Temperature(+260º) – Final Safety Validation

Finally, each hose undergoes a high-pressure hydrostatic test, bending test under temperature +300º~-60º), medium high temperature(+260º), tensile test(SAE J30) and Electrical breakdown test(SAE J30). These tests ensure that the hose can withstand extreme pressures without bursting or leaking, validating the hose’s strength and performance under high-pressure conditions. This final check ensures that each hose is capable of withstanding the demands of real-world applications.

Our Quality Commitment – Every Hose is Rigorously Tested

Through these comprehensive quality control steps, our PTFE 304 stainless steel braided hoses offer exceptional performance, including high-temperature resistance, corrosion resistance, and high-pressure endurance. We guarantee that each hose is tested to meet the highest international standards for reliability and safety, ensuring long-term performance and stability.

As a professional PTFE 304/316 stainless steel braided hose manufacturer, we are dedicated to providing our customers with high-quality, reliable products. With our advanced craftsmanship and rigorous quality assurance process, we are confident that our products will offer strong performance and long-lasting service for customers worldwide.
