Our precision-finished stainless steel pipes are engineered for excellence in demanding industrial environments. Through a series of specialized post-processing techniques, we transform premium-grade raw tubing into high-performance components renowned for their durability, precision, and reliability.

We offer stainless steel pipes that undergo a comprehensive suite of finishing processes to meet stringent application requirements. Each step is designed to enhance both the functional and operational characteristics of the pipe.

• Precision Expansion: Our cold-work expansion process ensures a precise internal diameter and an exceptionally smooth, burr-free interior surface, optimizing flow characteristics and preventing contamination.
• Durable Matte Finish: The sandblasting (or bead blasting) process creates a uniform, matte surface texture. This not only improves aesthetics but also increases surface hardness, wear resistance, and provides an excellent substrate for further coating or enhanced corrosion resistance.
• Functional Markings: High-contrast, permanent scale markings are applied with precision, facilitating accurate installation, fluid level monitoring, and safe operational use.
• Leak-Proof Taper Design: Precision-machined tapered ends facilitate a secure, firm fit with corresponding fittings, virtually eliminating the risk of leaks under pressure.
• Superior Sealing: End caps are processed and fitted with meticulous care to ensure a perfect seal, protecting pipe ends from contamination and damage during storage, transport, or operation.

We provide extensive customization to fulfill unique project specifications:

• Dimensions: Custom outer diameters (OD), wall thicknesses (WT), and cut lengths.
• Process Selection: A la carte or full-service selection of processes (expansion, sandblasting, marking, tapering, capping).
• Marking Specifications: Custom scales, unit systems, logos, part numbers, or barcodes.
• Taper & Threading: Specific taper angles, lengths, and custom threading on pipe ends.
• Material Grade: Selection of 304 or 316L stainless steel based on environmental needs.

• Primary Materials:
  • 304 Stainless Steel: Excellent all-purpose corrosion resistance, good formability, and weldability. Ideal for general industrial and architectural applications.
  • 316L Stainless Steel: Superior corrosion resistance, particularly against chlorides and acids. The low carbon content minimizes carbide precipitation, making it the preferred choice for harsh chemical, marine, and high-purity applications.
• Standards: Materials comply with ASTM A213, A269, A312, and other relevant international standards.

• Process Industries: As critical components in chemical plants, refineries, and power generation facilities.
• Sanitary Applications: For systems requiring cleanability and resistance to sterilizing agents.
• Measurement & Control: In level gauges, sight glasses, and sensor integration assemblies.
• High-Pressure Systems: For hydraulic and pneumatic applications where secure connections are paramount.
