Rubberlining to be applied in two 1/4" thick layers. Feather edges ofsecond layer. Tube seam to be on inside radius of elbow andbend.Rubber lining for valves to be carried to the outer edge of theraised flange face or for flat face flanged valves to the inside ofthe bolt circle. Full face lining is not required.Lining ProcedureApply remaining coats of adhesive using uniform coats andallowing each coat to dry before applying the next coat.Use adhesive cement of high quality material suitable formaximum adhesion between metal surface and crude rubbercompound.Dependent on pipe size, lay several lengths of coarse string fulllength of lining surface. Use no less than 3 lengths of string perlength of pipe.Cut sheet of rubber lining and form into a tube with O.D. of tubesame as I.D. of pipe. Ensure seam of lining is well knitted anduniformly smooth.Tackify the outside of tube, place tube on liner fabric and drawinto place in pipe using caution not to scuff or damage theadhesive cement. Remove the liner and with light air pressureexpand the rubber lining into place inside of pipe.Place pneumatic expander near centre of pipe length and

Pressure rating is a componentrequirement while design pressure and temperature is a system requirement. Changeddesign conditions maximum temperature from 150 to 149 F to be consistent with otherspecifications and changed operating conditions from 110 F to ambient temperature as thiswill be the normal temperature. Replaced paragraph with list of requirements in DesignFabrication Installation section for clarity. Added ASME B36.10 references to the PipeSection. The “lb .” was removed from Class designations per ASME definition. ANSI wasremoved from ANSI/ASME designations as ANSI/ASME is incorrect. Gasket section titlereplaced with Pipe Joint title and now includes welding section, flange bolts section andgasket section. Removed ZES reference from lockable valves note to be consistent withother specifications. Removed testing details from pipe preparation section as it is in thetesting section. Added component minimum rating.Section 5: Added table, added SPEC-35048 and PROC-83006 reference. Removed contentthat is in the SPEC or PROC for clarity. Corrected the test of 100 psig to 225 psig. Addeddrawing reference 99-999-G-4255.Section 6: Added Inspection to title. Added inspection criteria per code. Clarified examinationrequirements. Removed acceptance criteria note as it is covered in the Code.Section 7: Changed section title for clarity.Note: The above changes are applicable to any new installations and/or modifications toexisting systems from this date forward.Revision 2Approved for use in Thompson. Piping system approval requirements updated for Manitoba.Revision 1Document reviewed and updated against latest editions of referenced external standardsDocument format and number changed due to Vale engineering Document Programchanges in 2011.
