Petrolatum primer for the steel pipe anticorrosion
Petrolatum Primer for the steel pipe anticorrosion
A cold applied tape whick remains plastic over a wide temperature range .It is non-hardening and non-cracking .It is highly resistant to mineral acids,alkalis,salts and micro-organisms and highly impermeable to water,water vapour and gased.Used for the protection of buried or exposed pipes,rods, cable,valves and metal fittings from corrosion.
Non-woven snthetic fibre fabric impregnated and coated with a neutral compound based on saturated petroleum hydrocarbons(Petrolatum) and inert siliceous fillers.It is supplied in rolls in a range of widths.
1. Petrolatum Primer
High melting point petrolatum in hydrocarbon solven .The petrolatum primer is a semi solid paste for brush application.
2. Petrolatum Mastic
Petrolatum mastic is a cold applied self supporting mastic for sealing ,filling and caulking applications where a protective ,waterproof and non-setting mastic is required .Suitable for application in a wide range of climatic conditions,It is spcially recommended for duct sealing and around pipes and cables where they enter buildings to prevent the passgae of water or gas. It is used for moulding around irregular profiles such as flanges ,mechanical joints and valves to provide a contour suitable for wrapping with anti-Corrosion Tape e.g. XUNDA tape. Petrolatum compound containing inert siliceous fillers and vegetable fibres.It contain no volatile organic solvents.

1) Steel pipe pretreatment
1.1 Keeping the pipe external surface clean and dry.Remove the dust, oil, welding slag, burrs,
grease an dirt on pipe surface.
1.2 Pipe surface prepared up-to a level of Sa 2 or 2 ½ or St 2/st by sand blasting.
1.3 After the precleaning operations, the pipe surface not smoothwhich may sharp the pipe coating
should be burnished , the abrasive dust attached on the pipe surface should also be
1.4 If flash rusting occurs, the surfaces must be re-cleaned by blasting as above.
2) Coating &Wrapping application
2.1 Coating &wrapping application consist of primer application, inner tape coating ,outer tape
2.2 weather condition
2.2.1 When the wind&sand was strongly, when the sand and dust covered on the surface of pipe,
primer , tape etc., should not be brushing primer and wrapping the tape if there is
no reliable preventive measures.
2.2.2 When air humidity is greater than 80%,or when the pipe surface is wet from any precipitation,
should not be brushing primer and wrapping tape.
3) Brushing primer
3.1 The brushing time should be control within 6 hours between the pipe surface treatment and
brush primer.During brush primer, pipe surface should be free from damp and
pollution. If the pipe surface rust return, should be re-pre-cleaned.
3.2 The primer should be mixed evenly in the container before brushing.
3.3 The primer should be applied uniformly, without any sags, floods, runs, drips, bare spot and
over spray, such as leakage brush, clot, streaming. The primer coat DFT shall not be less
than 25-50micron (1-2mils)
3.4 After the primer dried, then wrapping the tape(It usually takes 3to 5 minutes.).
machine applicationapprox. 0,1 litre/m²
hand applicationapprox. 0,2 litre/m²
4) Wrap tape application
4.1 Wrap tape application consists of hand application and machine application.
4.2 The tape applied temperature must be above 5 degrees,the coating construction temperature
shall be more than -5 degrees as better .
4.3 The tape shall be spirally applied ,minimum overlap shall not be less than 50%.
4.4 When a new roll of tape started ,the ends shall be located to ensure the continuity of wrap tape
using the same method of application.
4.5 Outer tape applied method is the same as above.
Cutbacks shall be a minimum 6inches(150mm) from the ends of each pipe.The cutbacks may be
tapered or straight edge for the total thickness of the coating.
