With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
B31.1 table 132 gives you some relief on P11 and P22 material in the general notes, some of which are based on material thickness, carbon content, and other considerations. 3. If the person that made the original post could tell us what hardness testing equipment is being used it could shed some light on this issue alittle.

A335 P22 Pipes A335 P22 pipe is a kind of chrome moly pipes (ASME S/A335, Chrome-Moly) listed in ASTM A335, which has become a standard in the power generation industry and the petrochemical industry, not only because of its tensile strength, corrosion resistance and high-temperature strength, but also because of its cost-effectiveness.
ASTM A335 SPECIFICATION. The steel material shall conform to chemical composition, tensile property, and hardness requirements. Each length of pipe shall be subjected to the hydrostatic test. Also, each pipe shall be examined by a non-destructive examination method in accordance to the required practices.

Brinell Hardness value for SA 335 P 22 & SA 106 Gr B. Dear all After PWHT I want to check the hardness of the weldment,heat affected zone,parent metal of the welded joints. What is the brinell hardness value for the below two materials. Material SA 335 P22+SA 335 P22 Size 960 X 50 mm Material SA 106 Gr A+SA 106 Gr A Size 540 X 62 mm.
Once there is a qualified hardness testing procedure, hardness data should be evaluated against hardness requirements in ASME SA 335 for Grade 91 material - N&T (Grade 91, 265 HV or 251 BH, maximum). For the low end of hardness for N&T, I normally would use 190 HV for minimum hardness, 180 HV minimum (as verified by field replication of the p22 material hardness

A/SA369 material is manufactured in grades including FP11, FP22, FP5, FP9, FP91, and FP92 corresponding to the same grades listed above for A/SA335. Scope: This specification covers nominal wall and minimum wall seamless ferritic alloy-steel pipe intended for high-temperature service.
Hardness up to 300 Brinnell may be accepted, but any hardness over 300 is an indication of inadequate PWHT. SMAW and SAW weld metal will exhibit higher hardness when compared to GTAW and FCAW. Hardness below 175 indicates overheating of the joint, and such joints should either be replaced or the part should be normalized and tempered.
Piyush Steel is the leading Supplier and Exporter of P22 Pipe, AS P22 Pipe Material, We provide P22 Alloy Pipe in all shapes and sizes and with any specifications that the clients, ASTM A335 P22 is the part of ASTM A335, The pipe shall be suitable for bending, The ASTM A335 Grade P22 Pipe specification includes Chrome-Moly Seamless Alloy p22 material hardness
ASME B-31.3 codes allows maximum values of 241 HB for P-22 weld metals .Note in majority of the instances where P-22 material is used under B-31.3 design code PWHT is mandatory based on the design requirements.
The Brinell scale / b r n l / characterizes the indentation hardness of materials through the scale of penetration of an indenter, loaded on a material test-piece. It is one of several definitions of hardness in materials science .
Re: P11 & P22 Hardness Issue In Reply to Rashid Sultan at 14:40 Sep-14-2010. EQUOTIP is a portable hardness tester and comes with its own calibration blocks. It is independent of position (can be used in any position, horizontally, vertically up or down etc.) if my memory serves me correctly.
Piyush Steel Biggest Stockist and Suppliers of ASTM A213/ASME SA213 T22 Alloy Steel Tube in Mumbai India, South Africa, Uae, Malaysia, Singapore, UK, Saudi Arabia. We supply ASTM A213/ASME SA213 T22 Tubing in All Sizes.
ASTM A335 Seamless Pipes shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding. The steel material of ASTM A335 P5, P9, P11, P22, P91 SEAMLESS STEEL PIPES shall conform to chemical composition, tensile property, and hardness requirements.
CHROME MOLY/ALLOY STEEL VALVES F11/F22/F5/F9. Global Supply Line stocks and indents a large range of chrome-moly valves. These valves are manufactured from low alloy steel containing chromium and molybdenum making them suitable for higher temperature service especially for higher pressure and temperature combinations.
A335/SA335 Grade P22 Alloy Steel Seamless Pipes are Carbon steel pipes with addition of chromium, molybdenum, and sometimes vanadium. Chromium, or chrome, improves high-temperature strength, increases oxidation resistance and raises the tensile, yield and hardness at room temperatures.
For material heat treated in a batch-type furnace, tests shall be made on 5% of the pipe from each treated lot. For small lots, at least one pipe shall be tested. For material heat treated by the continuous process, tests shall be made on a sufficient number of pipe to constitute 5% of the lot, but in no case less than 2 pipe.
New power plants are in high demand and several hundred can be expected to be built over the next decade. Chromium-molybdenum steel pipe (P91) is a major construction material in these plants and there are particular methods for welding it properly to insure it will hold up.
ifferences in hardness between the base metal, weld metal, and HAZ for a P91 weldment are shown in Fig. 1. This trend for the HAZ to be a soft zone exists with all the CSEFs. Given that hardness can be an in-dicator for strength in low-alloy materi-als, the HAZ offers the least performance, regardless of the weld metal or base metal involved.
The material of steel should stick to the composition of chemicals, tensile property and the requirements of hardness. ASTM A335 P91 alloy steel pipe and high pressure boiler pipes are the two variants available and the range is dependent based on the size, which is solely based on the usage.

Grade F22 is a low alloy steel containing nominally 2.25% Chromium. The alloy is widely used in the oil patch wellhead applications for connectors, hangers and block valves. Hardness levels up to 22 HRC are approved to NACE MR0175. The grade is often used as the base metal for clad components.
The U.S. had been trying to develop a new material since the middle 1970s to bridge the gap between ferritic P22 and austenitic steels with respect to creep rupture strength for high-temperature service from 540 to 600 degrees C. Development of any new material, especially for high-temperature service, requires many years, because creep rupture strengths are established based on longtime p22 material hardness
The steel material shall conform to chemical composition, tensile property, and hardness requirements. Each length of pipe shall be subjected to the hydrostatic test. Also, each pipe shall be examined by a non-destructive examination method in accordance to the required practices.
