the company has always adhered to the business philosophy of "Integrity is our fundamental principle;Quality is our highest pursuit;Service is our greatest commitment;", insisted on being yourself first, and then doing good deeds, aiming at customer satisfaction, reputation first, and focusing on providing customers with first-class products and meticulous and efficient services.
As a low-carbon variant of 316 stainless steel (carbon content ≤ 0.03%), it contains molybdenum (2%-3%), chromium (16%-18%), and nickel (10%-14%). This chemical composition enables excellent resistance to chloride-induced corrosion (e.g., seawater, brine, and chemical solutions with chloride ions) and intergranular corrosion—a critical advantage for applications involving welding (no post-weld heat treatment is required to maintain corrosion performance, unlike standard 316). It also performs well in acidic, alkaline, and humid industrial environments, outperforming common 304 stainless steel in harsh corrosive conditions.
2. Compliance with EN Standards (Reliable Quality & Uniformity)
Manufactured in strict accordance with European EN standards (typical applicable standards include EN 10216-5 for seamless pipes and EN 10217-7 for welded pipes), the pipe meets rigorous requirements in multiple dimensions:
Chemical composition: Strictly controls the content of Cr, Ni, Mo, and C to ensure material stability.
Dimensional accuracy: Tight tolerances for square cross-section side length, wall thickness, and straightness (e.g., side length tolerance ±0.5mm for small-size pipes), avoiding deviations that affect installation and structural fit.
Non-destructive testing: Mandatory inspections such as ultrasonic testing (for seamless pipes) and pressure testing (for welded pipes) to eliminate internal defects (e.g., cracks, inclusions) and ensure leak tightness.
3. Structural Advantages of Square Cross-Section
Compared to round pipes, the square cross-section offers unique structural benefits:
Higher load-bearing efficiency: The flat, uniform cross-section distributes pressure and weight more evenly, making it ideal for structural applications (e.g., support frames, handrails, architectural columns) where stable vertical/horizontal load resistance is needed.
Space-saving & easy installation: The square shape allows for tight, neat assembly (e.g., parallel splicing, right-angle connections) without additional adapters, reducing installation time and space occupancy—suitable for compact industrial layouts or architectural designs.
Aesthetic consistency: Smooth, regular square edges enhance visual uniformity, making it a preferred choice for decorative or exposed applications (e.g., commercial building facades, furniture frames).
