    similar galling tendencies are used, they shall be lubricated with a suitable anti-seizure compound.

    4.3.3 If austenitic stainless steel parts exposed to conditions that promote inter-granular corrosion are to be

    fabricated, hard-faced, overlaid or repaired by welding, they shall be made of low carbon or stabilized

    grades.

    resistance at least equal to that of specified parts in the same environment. Seal / O-ring material betweenthe shaft and the shaft sleeve shall be verified by the Vendor/Contractor as being satisfactory for the service

    conditions.

    shall be performed by personnel and procedures qualified in accordance with Section VIII, Division 1 and

    Section IX of the ASME Code.

    and/or weld repaired, when the weldment is exposed to a process environment containing wet H2S. The

    PWHT procedure outlined in the ASME Code, Section VIII, paragraphs UW-40, UW-49, UHA-32 andUCS-56 shall be followed, except that notes in Tables UHA-32 and USC-56 do not apply. All welds,

    regardless of type or size, that are exposed to wet H2S shall be PWHT at a minimum temperature of 1100°F

    4.3.7 Connections welded to pressure casings shall be installed as specified below.

    Auxiliary piping welded to alloy steel casings shall be of a material with the same nominal properties as the

    casing material or low-carbon austenitic stainless steel. Other materials compatible with the casing material

    and intended service may be used with the Owner's approval.

    Radiographic NDE of welds is preferred but where this is not possible, due to nozzle orientation, magnetic

     particle or liquid penetrant inspection of welds will be required.

    Repair welding shall not be carried out without the Owner's approval including approval of the weld

     procedures to be used.

    4.3.8 Asbestos shall not be used in any form which can result in free asbestos becoming a health hazard. The

    Vendor/Contractor shall declare all asbestos use and submit alternative material for review by the Owner.

    4.4  Mechanical Seals 

    Springs shall be Alloy 20 or 316 stainless steel. Other metal parts shall be 316 stainless steel or another
