WEIGHT CALCULATION OF PIPE

W = 0,02466 x (D-t) x t (kg/m)

W = unit weight of pipe kg/mD = outside diameter of pipe (mm) t = wall thickness of pipe (mm)

UNIT SURFACE AREA OF PIPE

A = D x π x 10-3 (m2/m)2

Page 3: 205002968 Hydrotest Pressure Calculation

A = unit surface area of pipe m²/mD = outside diameter of pipe (mm)

HELIX ANGLE OF PIPE PRODUCTION

Cos θ = B / D x π (degree)

B = width of coil kg/mD = outside diameter of pipe (mm)

PRODUCTION TIME FOR 1 M. PIPET = 1 / Cos θ x V

T : production time (min) θ : helix angle of production V: Welding speed (m/min) (m/dak)

CALCULATION OF CARBON EQUIVALENT,

3

Page 4: 205002968 Hydrotest Pressure Calculation

For PSL 2 pipe, carbon equivalent (CE) calculations shall be based on the product analyses and shall be calculated as follows. All carbon equivalent results shall be reported: a. When the carbon content is less than or equal to 0.12%, the carbon equivalent shall be calculated using the following formula for CE(Pcm):

If the heat analysis indicates a boron content less than0.001%, then the product analysis need not include boron, and the boron content can be considered as zero for the CE(Pcm) calculation.

b. When the carbon content is greater than 0.12%, the carbon equivalent shall be calculated using the following formula for CE(IIW)

MAXIMUM CARBON EQUIVALENT,The carbon equivalent shall not exceed the following:a.For Grade X80 pipe, for all grades of seamless pipe having a specified wall thickness greater than 0.800 in. (20.3 mm) and for pipe designated by

the purchaser as high carbon equivalent pipe, the value agreed upon between the purchaser and the manufacturer.b.For pipe not covered in Item a above, a CE(Pcm) of 0.25%or a CE(IIW) of 0.43%, whichever is applicable.

Note 1: The CE(Pcm) formula for low carbon steel is commonlyc alled the Ito-Bessyo formula. CE (Pcm) is in fact the chemical portion of the full formula. Reference: Y. Ito & K. Bessyo, “Weldability Formula of High Strength Steels Related to Heat Affected Zone Cracking, Journal of Japanese Welding Society, 1968, 37, (9), 938.

Note 2: The CE(IIW) formula is commonly called the IIW [International Institute of Welding] formula. Reference: Technical Report,1967, IIW doc. IX-535-67.

1 Heat the steel surface to be insulated to 40-50ºC and clean to the purification degree 2 as per GOST 9.402. Treat the polyethylene coating with emery paper to provide sufficient surface roughness.

2 Heat the insulated surface and adjacent factory insulation coating to at least 90ºC (in summer) or 110 (+10) ºC. Apply the preliminary prepared epoxy primer onto the steel surface and the adjacent factory insulation coating over the entire insulated portion.

3 Wrap the sleeve around the weld joint so that the overlap with the factory coating is at least 75 mm at each side and the overlap of the sleeve ends is at least 100 mm.

4 Heat the glue layer with a soft flame on the closure plate and install the plate in the central position onto the sleeve end overlap by hitting it with a hand or rolling with a silicon roller. The closure plate should be located on the pipe circumference near the 2 or 10 o’clock position.

5 Heat the sleeve with a soft flame from the center to the edges beginning from the bottom part of the weld joint to remove bubbles from the sleeve surface.

APPLICATION PROCESS FOR REPAIR OF PE COATING

1 Heat the repaired polyethylene coating portion to 100 (+10ºC) and remove the damaged factory coating with a spatula or a knife. Smooth the sharp edges of the coating and make the coating more rough (with emery paper) over a 75 mm area around the removed coating portion. Remove rust from the repaired pipe surface portion with emery paper.

2 Heat the steel surface to 60ºC and polyethylene surface of the repaired portion to 100 (+10) ºC (within a 100 mm area around the damaged spot). Apply the repair filler (preliminary cut to size) onto the steel and polyethylene pipe surfaces. Heat the filler with a gas burner, fill in the damaged portion with a spatula and uniformly distribute it with the spatula over the polyethylene surface (over a 75 mm area around the damaged spot).

3 Heat the adhesive layer (preliminary cut to ensure 40-45 mm overlap with the factory coating). Heat until the adhesive layer becomes lustrous.

4 Install the tape onto the repaired pipe area so the tape adhesive layer extend from beneath the tape to at least 20 mm. Heat the tape with a gas burner and roll down with a roller remove glue blobs and air bubbles.

5Roll the tape down with a silicon roller to remove glue blobs and bubbles.
