WPS No: Rev.2:

VOSL-PL-1 (Rev.2) Date: September 23,2013Address change. WPS No. formerly VOSL-PL-1 (Rev. 1).

Scope: This welding procedure specification details the procedure to be followed for production field butt welding of pipe and/or components required by CSA Standard Z662, Oil and Gas Pipeline Systems.

Normative References: This welding procedure specification was prepared in accordance to CSA Z662-11 and incorporates by undated references, provisions from other publications. Revision to this specification is not required unless subsequent referenced code and or specification additions include changes to essential welding variables.

Service Restrictions: Sweet or Sour

Temperature Restrictions: Temperatures not requiring notch toughness properties.

1. WELDING PROCESS & METHODShielded Metal Arc Welding (SMAW) - manual method.

2. BASE MATERIALa) Composition: This specification applies to pipe and/or component material

manufactured in accordance with, or listed as "Acceptable Alternative Materials" in any of the following standards:

CSA Z662, 011 and Gas Pipeline SystemsCAN/CSA-Z245.1, Steel Line Pipe CAN/CSA-Z245.11, Steel Fittings CAN/CSA-Z245.12, Steel Flanges CAN/CSA-Z245.15, Steel ValvesPipe Grades: 359 MPa (SMYS) or less

c) Wall Thickness Qualified: 1.5 to 12.9 mm inclusived) Pipe Diameters Qualified: 60.3 to 323.9 mm 0.0. inclusivee) Carbon Equivalent: For sour service applications, CE to be determined by the

engineer in charge

3. FILLER METAL CLASSIFICATION & SIZEa) Root Pass: E60i0; 2.4, 2.5, 3.2 or 4.0 mm b) Hot Pass: E70i O-Pi; 3.2 or 4.0 mmc) Fill Pass(es): E70i O-Pi; 3.2,4.0, or 4.8,5.0 mmd) Cap Pass(es): E701 O-P1; 3.2,4.0 or 4.8,5.0 mm

The surfaces to be welded shall be smooth, uniform, free of fins, laminations, tears, scale, slag, grease, paint or other foreign matter, which may adversely affect the welding.

5. POSITION & DIRECTION OF WELDINGa) Position: Pipe horizontal, rolled or fixed position b) Direction of Welding: Vertical down

6. PREHEATING, INTERPASS TEMPERATURE & CONTROLLED COOLINGa) Butt Welds: A minimum preheat temperature of 1DoC shall be applied to an area

at least 50 mm on each side of the weld joint for its entire circumference prior to welding.

b) Repair Welds: A minimum preheat temperature of 120°C shall be applied to an area at least 150 mm from any point to the area to be repaired.

If the interpass temperature falls below the minimum preheat temperature, the entire weld joint shall be heated to the minimum preheat temperature prior to starting the next weld pass.

The maximum interpass temperature shall not exceed 200°C. Preheating may be applied by oxy-fuel torch, propane torch, electrical induction coils or any other method approved by the owner. Temperature of the joint shall be verified using temperature indicating crayons, thermocouples, pyrometers or other suitable method.

Where applicable, precautions shall be taken through the use of insulating covers or other means to control the cooling rate of the weld after any pass.

7. POSTWELD HEAT TREATMENTWelds prepared in accordance with this specification shall not be subjected to postweld heat treatment.

When external line-up clamps are used, the root bead shall be uniformly spaced around the circumference of the joint and, where practicable, shall have a cumulative length of at least 50% of the circumference prior to removal.Cleaning methods: Hand or power tools may be used. Each pass shall bethoroughly cleaned and free of slag and scale prior to depositing the next weld layer. The completed weld shall be brushed and free of spatter.Filler and Finish Beads and Finish to be achieved: The hot pass shall be started as soon as possible after the completion of the first pass. The completed weld shall have a substantially uniform cross-section for its entire circumference. The crown of the weld shall not be below the surface of the adjacent base metal.

10. REMOVAL AND REPAIR OF DEFECTSRepairable defects shall be removed by grinding. The minimum length of anyrepair shall be 50 mm. Welding shall be performed following the details outlined in this specification.
