Stainless Steel Tubes
7. When should I choose seamless stainless steel tubes over welded ones?
Seamless stainless steel tubes are ideal for high-pressure, high-temperature, or critical applications, such as boilers, heat exchangers, and the aerospace industry. Welded tubes are more cost-effective and suitable for general fluid transport.
8. How can I prevent corrosion of stainless steel tubes in various environments?
For high-corrosion environments (such as marine or chemical industries), it is recommended to choose 316 or higher-grade stainless steel. Regular cleaning and avoiding salt or chemical buildup can help. Surface treatments like passivation or electropolishing can also enhance corrosion resistance.
Stainless Steel Plates and Coils
9. Are your stainless steel plates and coils suitable for the food processing industry?
Yes, we provide food-grade stainless steel plates and coils, mainly in grades 304 and 316, known for their excellent corrosion resistance and ease of cleaning. These materials are widely used in food processing equipment, storage tanks, and kitchen utensils.
10. How do I choose the right stainless steel surface treatment for architectural decoration?
- Brushed Finish: Ideal for modern and industrial designs.
- Mirror Polishing: Used for high-end interior decorations and elevator panels.
- No.1 Finish: Suitable for outdoor structural components and heavy industrial applications.
Stainless Steel Round Bars
11. How do stainless steel round bars maintain dimensional stability during precision machining?
Our stainless steel round bars undergo strict heat treatment and surface processing, ensuring uniformity in material properties and dimensional accuracy, making them ideal for CNC machining, bolt manufacturing, and shaft components.
12. Can you provide special-purpose stainless steel round bars, such as heat-resistant or non-magnetic materials?
Yes! We offer heat-resistant stainless steels (like 310S) and non-magnetic materials (like 316L), to meet the unique requirements of various industries.
Flanges and Fittings
13. How do I choose the right type of flange for high-pressure systems?
For high-pressure systems, we recommend Weld Neck Flanges due to their robust structure and high pressure resistance after welding. For low-pressure or general systems, Slip-On or Threaded Flanges are more cost-effective options.
14. Are your fittings suitable for high-purity systems (such as in the pharmaceutical or semiconductor industries)?
Yes, we provide stainless steel fittings that meet high-purity requirements, with internal surfaces polished or electropolished to ensure contamination-free flow, widely used in the pharmaceutical, food, and semiconductor industries.
General Questions
15. How should stainless steel products be stored and maintained for long-term use?
Stainless steel products can be stored for long periods if kept in a dry, well-ventilated environment, avoiding exposure to moisture or acidic/alkaline environments. It is recommended to apply rust-preventative oil or protective film to extend their storage life.
16. How do you ensure that your products meet international quality standards?
We follow the ISO quality management system, and all products undergo composition analysis, mechanical performance testing, and surface treatment inspections. We can provide ASTM, EN, and other international certifications to ensure our products meet your quality requirements.
17. Do you support global shipping, and how do you ensure safe delivery?
Yes, we support global shipping. All products are packaged with protective materials (such as waterproof fabric, wooden crates, etc.) to ensure safe transport. We cooperate with experienced logistics companies to ensure on-time and safe delivery to our customers.
