As a leading manufacturer with a strong presence in global markets, Wuxi Yansheng Technology Co., Ltd. is proud to present our premium range of Variable Style Welded Stainless Steel Pipe Fittings. Engineered for demanding industrial applications, our fittings are crafted from high-grade 304, 304L, and 316L stainless steel, offering exceptional corrosion resistance and durability. With a modern factory spanning over 1,000 square meters and a dedicated team, we ensure consistent quality and reliable performance for piping systems worldwide, from North America to Southeast Asia.
Our welded stainless steel pipe fittings are designed to provide a secure and leak-proof connection in various piping configurations. The "variable style" designation means we offer a comprehensive selection of shapes and types to meet diverse project requirements.
- Superior Material Selection: We utilize premium austenitic stainless steel grades. 304/304L offers excellent general corrosion resistance and formability, ideal for a wide range of environments. 316L, with its added molybdenum content, provides enhanced resistance to pitting and crevice corrosion, particularly in chloride-containing environments, making it suitable for chemical, marine, and high-purity applications.
- Precision Welding & Manufacturing: Each fitting is manufactured using advanced welding techniques, ensuring strong, homogeneous joints with consistent wall thickness. This process guarantees structural integrity and smooth fluid flow, minimizing turbulence and pressure drop within the system.
-
Comprehensive Product Range: Our "variable style" portfolio includes, but is not limited to:
- Elbows (90°, 45°, 180°)
- Tees (Equal, Reducing)
- Reducers (Concentric, Eccentric)
- Caps
- Stub Ends
- Crosses
- Rigorous Quality Control: Our manufacturing process is supported by a robust quality management system. We conduct thorough inspections, including dimensional checks, visual examination, and material verification, to ensure every fitting meets specified standards and customer expectations.

Frequently Asked Questions (FAQ)
Q1: What is the main difference between 304, 304L, and 316L stainless steel for these fittings?
A1: The primary differences lie in composition and corrosion resistance. 304 is a versatile, general-purpose grade. 304L has a lower carbon content for improved weldability and resistance to sensitization. 316L contains molybdenum, offering superior resistance to chlorides and acids, making it ideal for harsh environments like marine or chemical processing.
Q2: Are these fittings suitable for high-pressure applications?
A2: The pressure rating depends on the material grade, wall thickness (schedule), and fitting design. We manufacture fittings to standard schedules (e.g., Sch 40, Sch 80) which have defined pressure ratings. Please provide your operating pressure and medium so we can recommend the appropriate specification.
Q3: Can you produce fittings in sizes or styles not listed in your standard catalog?
A3: Yes, as a manufacturer, we offer customization. We can produce fittings to non-standard dimensions, special angles, or unique configurations based on your technical drawings and requirements.
Q4: What surface finishes are typically available?
A4: Standard finishes include pickled (matte grey) and mechanically polished to various grit levels (e.g., 180G, 320G). Electro-polished finishes for ultra-clean applications or other specific finishes can be arranged upon request.
Q5: What documentation do you provide with the shipment?
A5> We typically provide a commercial invoice, packing list, and bill of lading. Material test certificates (MTC) or chemical composition and mechanical property reports can be supplied upon request for an additional charge.
Q6: What is your standard packaging to prevent damage during transit?
A6: Fittings are usually packaged in sturdy wooden crates or plywood boxes. Individual fittings may be wrapped to prevent scratching. We ensure packaging is suitable for long-distance ocean freight and handling.
Q7: How do I determine the correct fitting for my existing piping system?
A7: You will need to specify the nominal pipe size (NPS), schedule (wall thickness), and material grade of your existing pipes. Providing a simple sketch or part number can help us confirm the exact matching fitting.
Q8: What is your lead time for standard and custom orders?
A8> Lead times vary based on order quantity, material availability, and complexity. For standard items in stock, lead time is shorter. For large or custom orders, we will provide a production schedule upon order confirmation. We strive to meet agreed delivery timelines efficiently.
