ASME SA179 U Bend Tube Carbon Steel U Bend Tubes for Boiler Heat exchanger

 

 

ASTM A179 / ASME SA179 standard covers minimum-wall thickness, seamless cold-drawn low-carbon steel tubes for tubular heat-exchangers, condensers, and similar heat transfer apparatus. ASTM A179 / ASME SA179 standard requires that the tubes be heat treated after the final cold drawn pass at a temperature of 1200°F [650°C] or higher.

 

 

ASTM A179 U-Bending tubes are widely used in Heat-exchangers.

U-bent tubes for heat exchangers applied mostly in oil and gas plants, chemical and petrochemical plants, refineries, power plants and renewable energy plants. Low fin tubes can be supplied in the form of U bends.

Technical standards:

 

Other specifications or special requirements available upon request. Copies of common standard specifications are available on request.

 

Hydrotesting:

 

After heat treatment all U-tubes are hydrotested.

 

Minimum holding time at the required pressure is 5 sec.

 

All tubes are dried and carefully cleaned after testing.

 

Measuring, cutting, deburring, cleaning:

 

U-bends are measured exactly in accordance with relevant standards, or to customer’s specification.

 

All tubes are cut to the specified leg lengths, ends are deburred and the tubes are internally cleaned with air.

 

Before packing, both ends are capped with plastic caps.

 

Packing:

 

In strong, open or closed, wooden boxes depending on destination - max. 8,000 kg.

 

Ends of tubes protected by plastic caps.

 

Vertical separators for each radius.

 

Chloride free plastic separators between each row, every 2 meters.

 

Each bundle is covered with plastic.

 

Customers can provide a packing drawing.

 

Packing lists, covered with plastic, are placed on each wooden box for easy identification of order details – including exact list of radii and lengths inside.
