Oily petrolatum
Oily petrolatum anti-corrosion tape manual
1. Product overview
Oily petrolatum anticorrosive belt system is a system that is truly non-toxic, does not contain volatile components and has excellent anti-corrosion performance. It was originally invented specifically for the external anticorrosion of steel and cement piles in seawater. Now it has been widely used for long-term corrosion protection of various equipment in the harshest atmosphere, underground and underwater environments.
With its excellent plasticity and flexibility, the system can be kneaded into any shape, so it is suitable for the anti-corrosion and maintenance of any shape of equipment such as flanges, valves and other pipe fittings, as well as the anti-corrosion after emergency repairs, such as oil, gas, and transportation. A large number of valves, flanges, tees, condensate tanks, underground storage tanks, vertical tanks, pipelines, equipment, steel structures, seawater in the water and petrochemical industries, as well as in various stations and factories, shipbuilding, ship repair and other industries China steel piles, cast iron pipe sockets and other places. More than 50 years of construction and application experience has proved that the anti-corrosion system based on petrolatum is simpler, more efficient, safer and more durable than traditional coatings in the past.
It is also one of the most suitable anti-corrosion material systems for special-shaped equipment in the world. It is also the first choice for water-proofing, flanges, valves and other pipe fittings of storage tanks, and anti-corrosion of subsea steel piles; specific construction technology can refer to the construction technology separately provided by our company Program specification.

In the past, we often ignored the anti-corrosion problem of these equipment, just painted some paint, after a certain period of corrosion, these workpieces and equipment exposed to the humid and corrosive environment for a long time were severely corroded, resulting in leakage and unusable, causing serious loss. With this system, the possibility of continued corrosion of the workpiece and equipment can be completely stopped, and it can be reused, which is very convenient for daily maintenance and greatly saves the cost of daily maintenance. From the perspective of short-term and long-term economic benefits, social benefits and equipment anticorrosion and prolonged years, this system is the most suitable.

3、anti-corrosion principle:
The system includes four parts: sealing ointment (petrolatum primer), sealing putty (petrolatum mortar), oily petrolatum tape, and PVC outer protective tape. The combined system, based on its main component-oily mineral grease, hydrophobic and non-hydrophilic anti-corrosion mechanism, makes the surface of the workpiece form several consecutive layers of grease waterproof sealing layer, and the equipment is always protected by a thick grease sealing film Bottom, the oil film layer does not fall off, does not age, does not solidify, does not crack the flexible characteristics, so that the system can adapt to the thermal expansion and contraction of the workpiece, providing long-term sealing protection for the workpiece. Water vapor can't penetrate at all, and the effect is more obvious in humid, underwater, seaside, and buried environments.
The petrolatum anticorrosion system is mainly composed of saturated inert petrolatum, which is resistant to corrosion by inorganic acids, alkalis, and salt substances, and has good electrical insulation. The construction of mineral ester oil-based anti-corrosion tape system is very simple and easy, and it can be directly constructed in water, which is unmatched by any other anti-corrosion layer. This system does not contain any volatile components, is non-toxic and harmless, and meets various strict international environmental protection requirements.
