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.

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
