With an unwavering emphasis on quality, accuracy, and performance, the organization provides state-of-the-art air distribution systems for industrial and commercial requirements. Their stainless steel manifolds are constructed from high-quality material to provide superior durability, corrosion resistance, and uninterrupted airflow. Utilizing advanced manufacturing processes and rigorous quality control, Paul Tube Fittings has established itself as a name that can be relied upon in the business, catering to industries like oil and gas, chemical processing, and HVAC with efficient, effective, and durable manifold systems.
Stainless steel air manifolds are generally made of 304 or 316 stainless steel, which are highly resistant to corrosion and have excellent mechanical strength. The alloy content consists of iron, 18–20% chromium, 8–10.5% nickel, and traces of carbon, manganese, and silicon. These manifolds are characterized by high tensile strength (>515 MPa), satisfactory yield strength (≈205 MPa), and very good elongation, generally up to 40%. Its mechanical properties render it for high-pressure and high-temperature use with long service life, resistance to cracking or deformation, and low maintenance under harsh conditions.
