Whats the difference between API 5L Gr.B and A106 Gr.B? API5L GRb Pipes come from API Spec 5L Specification for Line Pipe with the application of gas, water and oil transportation. Standard Line Pipe has grade designation A and B. API 5L Grade b pipe can be two of API 5L product service level (PSL),thats is API 5L Gr.B PSL1 and API 5L Gr.B PSL2.
ASTM A106 Pipe Specifications | American Piping Products
ASTM A106 seamless pressure pipe (also known as ASME SA106 pipe) is commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers, and ships where the piping must transport fluids and gases that exhibit higher temperatures and pressure levels.

The base metal hardness for A105 was 155-160BHN & for pipe A106 GrB was 135-138 BHN before fabrication. After welding & PWHT(stress relieving at 620 deg C for 2hrs)the hardness for A 105 was 111-120 BHN & that of for A 106 GrB was 102-108 BHN.The weld hardness was between 175-180 BHN.
Investigation of Residual Stresses on Post Weld Heat ...
AbstractIn this paper, the effects of post weld heat treatment (PWHT) by ceramic pad heater to relieve residual stresses of an A106GRB carbon steel pipe is presented. At first, the pipe was welded in 3 passes by GTAW and SMAW process. The thermal cycle was measured during welding with k-type thermocouple.
Difference between ASTM A106 & A333 - hghouston.com
I believe A333 is a good substitute for A106-B for a broad range of temeperatures Based on my review of ASME B31.3 (Table A-1) the allowable stress for A106 Grade b is 16ksi to 500F; for A333 grade 6 - 20Ksi to 400F and 18.9ksi to 500F It would be fair to say that, given the application has an operating temperature greater than -20F, either pwht a106 grb

A335 P91 | P91 Material | SA335 P91 | ASTM A335 P91
There are particular methods for welding it properly to insure it will hold up. Welding A335 P91 generally requires preheating the joint, maintaining interpass temperatures, hydrogen bakes, and postweld heat treatment (PWHT). Preheating, typically to 400 to 500 degrees F, drives off moisture and thereby reduces hydrogen. Welding is one process that is widely used during the construction.

The Importance of Correct Post Weld Heat Treatment (PWHT).
Post Weld Heat Treatment is a mandatory requirement for the fabrication and construction of pressure vessels. The residual stresses formed during welding can cause metal failures. The macro structure also changes during the welding process and makes the steel weak. PWHT removes these stresses and restores the macro structure of the steel.

Where tempering treatments are all carried out at the same temperature, the effects are additive, and the times are simply summed. (An allowance for the time elapsed during heating and cooling cycles is discussed below).

Pipe qualification - American Welding Society
Well, from what I can see, regardless of the usage of D1.1 or ASME it appears the welder who qualified per the A53 gr B is also qualified to weld the A106 gr B per the codes. The ONLY glitch I see is trying to understand what your statement referred to about the A106 and an applicable WPS. In D1.1 there is no problem.
