The tubes are annealed above the upper transformation point in a controlled atmosphere or under vacuum. Our team are highly trained and experienced in adtm and producing all types of steel supplies. After the last heat treatment there is a light finishing pass cold drawing With proper subsequent processing, the tube can be cold-formed e. The values stated in either inch-pound units or SI units are to be regarded separately as standard.

ASTM A192 Carbon Steel Tube

The length can be fixed or random. Inspection personnel are trained and uncover the appropriate qualifications for testing seamless boiler pipes. This specification has been approved for use by agencies of the Department of Defense.

Piercing process The cross roll piercing and pilger rolling process in the size range from approx. Pipe weld cracks often follow different mechanisms can be divided into two types of thermal cracking and cold cracking. Brinell hardness should not exceed HB for those pipes with the wall thickness of during or equal to 0.


Hydrostatic or Nondestructive Electric Test 2.

This specification covers minimum-wall-thickness, seamless carbon steel boiler and superheater tubes for high-pressure service. Free of scale,A aatm amount of oxidation will not be considered as scale.

Iwowwee configures multiple inspection machines, such as British UNICORN ultrasonic joint inspection machine, magnetic particle testing machine, eddy current testing machine furthermore has professional personnel. How to make seamless pipe seamless pipe process? The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.

It is typically used for manufacturing ruthless boiler The working pressure is not more than 9. The tubes therefore have only low deformability. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Pressure to succeed resistance is guaranteed in the very smooth inside material. Tubing having other dimensions may be furnished, provided such tubes comply with all other requirements of this specification.

JST hot-rolled high pressure seamless boiler pipe does not need heat treatment. After the final cold-forming process the tubes are annealed in a controlled atmosphere or under vacuum. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order.

The tubes shall have a hardness number not exceeding a specific value.

ASTM A, ASTM A Seamless Steel Pipe

JST owns professional hardness testing equipment and professional testing personnel for testing seamless boiler pipes. Drill Pipe Drill Collar. As stated by customers’ requirements, JST high-pressure seamless carbon steel boiler tubes can do flaw detections.


This abstract is a brief summary of the referenced standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. JST is capable to provide seamless boiler pipes with specific size, diameter and minimum wall thickness. This guide covers standard specifications for minimum-wall-thickness, seamless carbon steel aetm and superheater tubes for high-pressure service.

Historical Version s – view previous versions of standard. Pipe fittings are necessary to join a912 pipes, or to change the direction of an existing pipe. No heat treatment after the last cold-forming process. Link to Active This link will always route to the current Active version of the standard. If requested by customers, home furniture also provide inspection reports.
