The seamless pipe of ASTM A335 P11 is a typical Cr-Mo alloy steel pipe for high-temperature service. Also known as 1.25Cr-0.5Mo, the UNS designation of ASTM A335 P11 is K11597. Its ASTM equivalent includes ASTM A369 FP11 as well as ASTM A213 T11. Usually, the pipe shall be furnished with either butt welding(BW) or plain ends(PE).
 

P11 Pipe Applications

Due to the ferrimagnetic characteristics of iron, a few steel alloys in A335 P11 pipes can be used in applications where their reactions to magnetism are important. This includes transformers and electric motors. P11 is also a popular grade for many different applications such as:

1. Spacecraft
2. Turbine blades of jet engines
3. Nuclear reactors

Heat Treatment, Inspection & Test

Pipes of ASTM A335 P11 may be either cold drawn or hot rolled. Each pipe shall be reheated for heat treatment - full or isothermal annealing, normalizing and tempering at a temperature no less than 1200°F(650°C).

Hydrostatic test shall be performed on each pipe length of ASTM A335 P11 along with dimensional inspection and visual examination. Longitudinal or transverse tension test, flattening test, or bend test shall be performed for each heat number of furnace. When specified by the purchaser, one of the alternative nondestructive tests can be performed: ultrasonic test, eddy current test, or flux leakage examination. Hardness test is not necessary.

ASTM A-335M Grade P11 tube Packaging & Shipping

ASTM A335 P11 Steel Pipes may be furnished bare or coated and with capped ends. Tubes and pipes up to 3" OD will be supplied in bundles. In order to prevent rust during sea shipment, bundles of ASTM A335 P11 tubes may be wrapped with polypropylene sheets, and secured with flat steel bands. Over 3" OD will be supplied loose.
