Product Description

ASTMA213 Stainless Steel SEAMLESS HEAT EXCHANGER TUBE & U TUBE

Product Description

Material Summary

Good oxidation resistance in intermittent service to 870°C and in continuous service to 925°C. Continuous use of 316 in the 425-860°C range is not recommended if subsequent aqueous corrosion resistance is important.
Grade 316L is more resistant to carbide precipitation and can be used in the above temperature range.
Grade 316H has higher strength at elevated temperatures and is sometimes used for structural and pressure-containing applications at temperatures above about 500°C.

Applications

Heat exchanger is a device used to transfer heat between a solid object and a fluid, or between two or more fluids at different temperatures, transfer heating from higher temperature fluid to lower temperature object to make fluid temperature to specified requirement, for stainless steel grades, there are shell and tube heat exchanger, plate heat exchangers, plate and shell heat exchanger and other heat exchanger, tube heat exchanger consists of a number of tubes inside bundle and sheet, widely used in many industries.

• Space Heating
• Refrigeration
• Air Conditioning
• Power Stations
• Chemical Plants
• Petrochemical Plants
• Petroleum Refineries
• Natural-Gas Processing
• Wine And Beer Making

Packaging & Shipping

1.generally export packing

   -packed by knitting strips in bundles

2.It is suggested that the pipes OD under 25MM or Less than container shipment are packed by plywood cases, which can protect pipes better.
