ASME Standard Seamless Serpentine Tube Stainless Welded Carbon Coil

ASME Standard Seamless Serpentine Tube Stainless Welded Carbon Superheater Coil

Specific requirements are:

1. Superheater and steam pipe metals are required to have sufficiently high creep strength, durable strength and durable plasticity.In the calculation of superheater tube strength, the high temperature endurance strength limit is the main basis, and then the creep limit is used to check.When the metal of superheater tube is of high lasting strength, on the one hand, it can guarantee the safe operation under creep condition, on the other hand, it can avoid the difficulty in processing and operation caused by too thick tube wall.

2. It is required that the metal of superheater tube has good stability in microstructure and properties during long-term operation at high temperature.

3. Good process performance is required, especially the welding performance is good.The superheater tube is also required to have good cold working performance.

4. High oxidation resistance of steel is required.It is generally required that the superheater tube metal be oxidized to a depth of less than 0.1 mm/year at operating temperature (i.e. tube wall temperature).

Serpentine Tube Introduction

Serpentine Tube are widely used in Heat Exchanger Systems.

The function of the superheater tube is to absorb heat. The seamless boiler steel tube or heat-resistant alloy steel tube is bent into a snake shape, and both ends are welded to the inlet and outlet containers respectively.

The Serpentine Tube Comply With The Following Standards:

1. ASTM A688/ASME SA688

2. ASTM A803/ASME SA803

3. ASTM A556/ASME SA556

Steel Grade:

Tube Of Other Alloys And Steel Grades Can Be Produced Upon Agreement.
