Re: [MW:22951] X70 API 5L "PSL2".

By Materials & Welding

Dear Zenoto,

Please find out if you can use E 8010 G wherein the tensile strength specified in the MTC of electrode is more than 82 ksi which shall meet the requirements for API 5L X70 as per trailing mail.

In case yes, note to be incorporated in WPS that MTC of each lot of electrodes shall be verified for the minimum requirement of 82 ksi ( instead of 80 ksi).

Regards,

Anup

Dear Zenteno,

As per API 5L, PSL 2 class pipes' minimum tensile strength requirement is 82000 psi .It may be reason for advice by the audit team for E-9010 electrode ,which can deposit weld metal having min. tensile strength of 90000 psi ( above the tensile of pipe)

Dear experts.

For pipeline construction, diameter 20 ", thickness 12.7mm and 20,62mm, as API 5L X70 steel" PSL2 "(attached image). We had considered making welding procedures (mechanical tests) SMAW process standard API 1104 with E8010- G.

Inspection (audit) requires us to accomplish with E9010-G, according to inspection (audit) E8010-G does not correspond to API 5L X70 "PSL2".

Please give me your opinion on this technique to determine further action.

Thanks and regards.

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

By Materials & Welding
Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...

Re: [MW:10788] ON PLOT PIPING & OFF PLOT PIPING

By Materials & Welding
Piping systems involved for the flow lines and gathering lines from the well head isolation valve to the production facility or processing plant isolation valve are determined as OFF PLOT. ON PLOT defines piping system in the processing plant and production platform. ANSI/ASME B31.4 applies for off plot piping system. B31.4 allows the use of either API 1104 or ASME section IX (as appropriate). However, occasionally, a very small system such as piping within 500 feet of a processing plant (some client also said 400 feet) may be declared B31.3 rather than B31.4. When B31.3 is invoked, only ASME Section IX is used. before you decide which code to use for welding procedure and/or welder qualification for pipe welding, you have to know the design and construction code applicable to the system. Please read far enough into scope and diagram illustrating the application of either B31.3 and B31.4 hope this helps rgds 2011/4/21 pradip kumar sil < pradipsil@gmail.com > Dear all, ...
