What is SA213 tp347h material?

SA213 TP347 / 347H is a seamless ferritic and austenitic alloy SS (Stainless Steel) boiler tube used in superheaters, and heat exchanger tubes.

TP347H is a stabilized austenitic stainless steel that is used in reheaters, heat exchangers, and superheaters. It is a corrosion-resistant material with a high creep strength. The high carbon content of TP347H gives it extra toughness. The chemical composition of TP347H includes: Silicon, Chromium, Nickel, Columbium +Tantalum.

TP347H has been used as the material of tubes in 600°C USC power plants in China. It can be easily elongated by 40%.

What is the difference between 347 and 347H?

347H is the higher carbon version of 347 plate. Due to the additional carbon present in 347H plate, it is tougher and generally more durable than 347 plate. These grades of stainless steel plate is available in a wide range of sizes at Penn Stainless Products.

This grade of stainless steel has an elongation of 40%. On the Brinell hardness scale 347 and 347H stainless steel plate has hardness of 201 and on the Rockwell B scale, both 347 and 347H have a hardness of 95.

What is the composition of SA 213 TP347H U bend tube

Both contain between 17.0% and 20.0% chromium, and no more than 2.0% manganese. They are made of between 9.0% and 13.0% nickel. 347 stainless steel plate contains at most 0.04% phosphorous while 347H stainless steel can only contain up to 0.03% phosphorous.

PMI test for TP347H

Positive Material Identification (PMI) testing for TP347H involves the analysis of the chemical composition of the material to verify its alloy content and ensure it meets the required specifications.

TP347H is a high-temperature stainless steel alloy often used in applications like boiler tubes and heat exchangers. PMI testing is crucial to confirm that the material is indeed TP347H and that it meets the necessary alloy composition standards.

Flattening Test

Flattening tests shall be made on specimens from each end of one finished tube, not the one used for the flaring test, from each lot.

Flaring Test

Flaring tests shall be made on specimens from each end of one finished tube, not the one used for the flattening test, from each lot.

Hydrostatic and Nondestructive Testing

Each TP347H Stainless Steel Seamless pipe shall be subjected to the nondestructive electric test or the hydrostatic test. The type of test to be used shall be at the manufacturer’s option unless otherwise specified in the purchase order.

• 100% Ultrasonic Testing
• 100% Eddy Current Testing
• 100% Hydrostatic Testing

What is the difference between 347H and 316L?

347 and 316 stainless steel both fall into the 300-series family and are known for their stability. While 316 is a standard alloy that offers superior weldability, 347 offers superior corrosion resistance and mechanical strength.

Markings

Markings will adhere to prescribed specifications in A999/A999M. They shall include the NPS or OD and schedule number or average wall thickness, heat number, and NH (when hydro testing is not performed) and ET (when eddy-current testing is performed) or UT (when ultrasonic testing is performed). The marking shall also include the manufacturer’s private identifying mark, the marking requirement of section 12.3 on Hydrostatic or Nondestructive Electric Test, if applicable, and whether seamless (SML), welded (WLD), or heavily cold-worked (HCW). For Grades TP347 and TP347H Stainless Tubes, the marking shall also include the heat number and heat-treatment lot identification.

Note:

• Mill test certificates will be issued according to EN10204-3.1 or 3.2
• All tubes shall be supplied as per applicable ASME SA213/213M Specification.

What are the uses of U bend tube?

U-bend tubes are used to transfer heat between fluids. They can return the flow of coolants/fluids at 180 degrees in a much smaller space.

The common application fields are: heat exchangers (condensers, evaporators, sea water desalinators) chemical and petrochemical industries. food processing and refrigeration industries.

Why is U-bend used in pipeline?

As the pipes warm up they expand, the bend allows this expansion to proceed without buckling the pipes. Alternatively, flexible or sliding types of expansion provision are available, and large pipes are mounted on rollers.
