ASTM A213 PVC Coated Steel Pipe Seamless Austenitic Stainless Steel Pipe For Insulation

Material

ASTM A213 covers seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. Among these, seamless austenitic stainless steel pipes are widely used due to their excellent corrosion resistance, high-temperature strength, and ductility. The base material is typically an austenitic stainless steel, with popular grades including 304, 304L, 316, and 316L.

The PVC coating on steel pipes serves as a protective layer, enhancing corrosion resistance especially for insulation applications by providing additional barrier protection against moisture, chemicals, and physical damage.

Mechanical Properties

Key Features

• Corrosion Resistance: Austenitic stainless steel composition provides excellent resistance to rust, pitting, and crevice corrosion.
• Seamless Construction: Provides superior strength and reliability with no weld seams, suitable for high-pressure applications.
• PVC Coating: Enhances corrosion resistance, protects against external environmental factors, and supports thermal insulation.
• High Temperature Resistance: Suitable for boiler and heat exchanger applications in high temperature environments.
• Ductility and Toughness: Maintains strength even in cryogenic and low-temperature applications.
• Low Maintenance: Extended service life with reduced maintenance needs due to protective coating.

Application

• Boiler tubes and superheater tubes in power plants
• Heat exchangers and condensers in chemical processing plants
• Petroleum refineries
• HVAC systems with insulation requirements
• Industrial piping requiring corrosion protection and insulation
• Structural piping in marine and offshore environments
