The External Corrosion Specialist(Cathodic Protection, Heavy Duty Coating, HDPE / Petrolatum Tape & Composite Wrapping)

SPLASH GUARD SYSTEM

SPLASH GUARD SYSTEM

I. Introduction

TAM Splash Guard System were develop forexcellent corrosion of :

- Steel and Concrete Piling- Pipes- Valves- Flanges- Other steel structure

That immerse in sea water, in the splash zone area and buried in the soil.

Element of a corrosion cell must be present are :- Anode- Cathode- Metallic connection- Electrolyte (water or soil)

TAM Splash Guard Systems are design to stopping corrosion by creates a solidbarrier between electrolyte (sea water or soil) and the steel surface by PetrolatumTape.

Petrolatum Tape is defined as “a purified mixture of semisolid hydrocarbonsobtained from petroleum, occurring as an unctuous mass.” Petrolatum is a soft,viscous, moisturizing material, which adheres comparatively well to rusty orslightly-moist steel. This material has some moisture-displacing capabilities andgenerally only requires cleaning by hand or power-tool cleaning.

Petrolatum tape is composed of synthetic fabric, filled with a petrolatumcompound, inert fillers and special anti-corrosion agents.

TAM Splash Guard system are proven effective and long life corrosion protection foroffshore environment.

2 mm or 3 mm thickness high density Polyethylene outer cover (HDPE) will be installedfor prevention of mechanical damages and for the good performance of the wrappeditem

SPLASH GUARD SYSTEM

TAM Splash Guard System offers excellent protection against corrosionand creates a solid water barrier.Petro tape has good resistance to acids, alkalis and salt.

II. Characteristics

Long term protection andapplicable to various places inground, marine, underground andany kinds of pipes.

Great efficiency with easyapplication and short workingtimes.

Hygienically harmless and non-polluting

A very high degree ofimpermeability to water. Nocracking and hardening.

Good resistance to acids, alkalisand salts. No changes in qualityunder low

B. Procedure HDPE Jacketing Type Girder

B.1 Surface Preparation

Preparatian

Co-ordinate with owner / main contractor site staff and others related parties.

Prepared applicator, tools/equipment, and material to work at site. Consist of :

- Drum Pontoon should be ready available

- Tools, dive equipment, Safety equipment, and Material to be installed should be

ready & available

Surface preparation Application

Cleaning method should be match with the product mentioned in the manufacturer

coating specification for the involved project.

Cleaning equipment used should be inline to the recommendation of the manufacture

coating specification.

Degree of Surface Preparation

SSPC SWEDISH NACE DESCRIPTION

SP2, Hand Tool

Cleaning

St 2 N/A Removal of loose rust, loose mill, scale

and loose paint by hand chipping,

scraping, sanding and wire brushing.

SP3, Power Tool

Cleaning

St 3 N/A Removal of loose Removal of loose rust,

loose mill, scale and loose paint by

power tool chipping, descaling, sanding,

wire brushing and grinding.

All surfaces to be wrapped shall be cleaned of oils, grease, tar, and tide scum residues

All marine growth, loosely adhering coating and heavy corrosion scale shall be removed

Welds scars, welding slag, spatter, scale and sharp edges must be cut away and must have

smooth ground surface


B.2 Primer Paste

After Surface preparation completed and inspected immedeately apply Primer Paste. It

is used in the initial treatment of metal surfaces prior to wrapping. Primer Paste displaces

moistore, passivates surface oxides, fills surface imperfaections and ensures adhesion

between Petrolatum Wrapping Tape and the substrate.

For underwater application, Primer Paste can be applied direct to the Petrolatum Tape at

above water before underwater application.

Primer Paste is applied to the prepared steel by gloved hand. Primer Paste should be

applied in a circular motion, obtaining a thin even film that fills all cavities.

ready & available

Primer Paste Application

After proper surface preparation sharp edges must be cut away and make sure pipe

surface is smooth.

Above WaterApply paste by hand (glove), brush in circular motion, obtaining a thin and even films

(0,5 kg/m2).

Under WaterApply paste by hand (glove) direct on the tape surface. Obtaining a thin and even film

on the tape surface (0,5 kg/m2).

B.3 Petrolatum Wrapping Tape

For corrosion protection, sealing and waterproofing of atmospheric and buried or

submerged metal surfaces. The high degree of conformability of Petrolatum Wrapping

Tape allows for application over irregular surface profiles. Petrolatum Wrapping Tape is

made from stitch-bonded synthetic fabric that is fully saturated and coated with a neutral

petrolatum compound and blended with inert fillers and corrosion inhibitors.

ready & available

Petrolatum Wrapping Tape Application

Determine distance from underside of the jetty deck, to bottom of the area to be

protected

Measuring of the length of pile to be protected, length refer to data from owner.

Remove the the thin plastics that cover the wrapping tape.

Tape shall be applied spirally from top to the bottom of pile until above of pipe

protected.

Place the beginning of the roll against the pile.

Starting from the top with 2 layers =30% – 50% overlap

Make (one) full circumferential wrap around the pile, rub down to ensure a good bond

Continue to wrap around the pile following spiral path with a minimum overlapping of

1 inch.

During wrapping application, make sure proper tension in applied and minimum

wrinkles are present.

- Outflow of the water and air bubles trapped from inside the tape.

- Avoid rinkles and smooth performance

- Seal overlapping the tape.


Under Water Application

Once, the wrapping get in to under water, application will be done by qualified diver

and proper dive equipment (regulator, surface compressed air etc)

Continue to wrap as describe above, until the end of the length of the pile to be

protected is reached.

The wrap is completed at the bottom, with another double turn (100% overlap), to

ensure a double thickness of the tape

B. 4 HDPE Outer Cover

The HDPE Outer Cover is a high quality formulation of UVR stabilized polyethylene. It

contains approximately 97,5% polymer and 2,5% carbon black, anti-oxidants and heat

stabilizers. The HDPE Outer Cover is designed specifically for exposed conditions. It

contains no additives, or fillers, which can leach out and cause deterioration over time.

Each sheet is fabricated to the required size of the structure to be protected. HDPE Sheet

to be used is 2.0 mm thickness.

Preparatian





ready & available

HDPE Outer Cover Application

The cover have been pulled tightly around the wrapped pile and there are no loose

areas where the cover is not touching the wrapped pile

Squeeze HDPE Girder on the Outer Cover with the other side of HDPE Girder .

Install the Girder clamp with two bolts at the top and bottom position

Press 2 HDPE Girder using the hydraulic hand pump / jack

Pair the SS 316 Nut Bolt in HDPE Girder and tightened using a wrench .
