Product Description

Pressure Tube Astm A213 Seamless Alloy Steel Pipe is a specialized high-pressure tubing solution engineered to excel in systems where extreme pressure and temperature conditions demand uncompromising strength and reliability. Compliant with the rigorous ASTM A213 standard for seamless alloy steel tubing, this pressure tube is designed to withstand intense internal and external pressures, making it an essential component in power generation boilers, high-pressure heat exchangers, petrochemical process lines, and industrial Pressure Vessels.

The seamless construction of ASTM A213 pressure tubes is critical to their pressure-handling performance. By eliminating welded joints—vulnerable points where pressure can cause leaks or failure—seamless design ensures uniform wall thickness and material density, creating a continuous barrier against pressure. This structural integrity is further enhanced by precise manufacturing techniques that ensure consistent dimensional tolerances: outer diameter (OD) tolerances of ±0.75% for smaller sizes and ±0.5% for larger diameters, and wall thickness tolerances of +12.5%/-10%. These tight tolerances guarantee that the tube can withstand designed pressures without thinning or bulging, even in high-temperature conditions that expand the material.
Compliance with ASTM A213 standards includes rigorous pressure testing to validate performance. Each tube undergoes hydrostatic pressure testing at 1.5 times the maximum operating pressure, ensuring it can handle unexpected pressure spikes. Additional tests, such as burst testing and fatigue testing under cyclic pressure, confirm the tube’s ability to endure long-term pressure stress without degradation. Non-destructive inspections (ultrasonic and eddy current testing) detect microdefects that could compromise pressure resistance, while chemical analysis verifies alloy composition to ensure pressure-related properties like tensile strength and ductility meet exacting standards.
Versatility makes Pressure Tube ASTM A213 Seamless Alloy Steel Pipe adaptable to diverse high-pressure systems. Available in diameters from 6.35 mm (0.25 inches) to 152.4 mm (6 inches) and wall thicknesses up to 12.7 mm (0.5 inches), it fits applications ranging from small-bore high-pressure steam lines to large-diameter pressure vessel tubing. Its compatibility with high-pressure fittings and welding techniques simplifies installation, ensuring leak-tight connections that maintain system pressure integrity.
In industries where pressure failure can lead to catastrophic consequences—from power plants to oil and gas refineries—Pressure Tube ASTM A213 Seamless Alloy Steel Pipe stands as a trusted solution. It combines advanced alloy properties, seamless structural integrity, and ASTM-certified pressure resistance to deliver a tubing solution that excels under the most extreme pressure conditions.
Choose Pressure Tube ASTM A213 Seamless Alloy Steel Pipe for your high-pressure systems and ensure safety, reliability, and performance—backed by the rigor of ASTM standards and engineered to withstand the forces that define your operation.
