Ceramic Polymer: Internal coating of slug catcher pipelines for the extraction of natural gas

During the extraction process, natural gas is very humid and therefore highly corrosive. Due to the high pressure and absorbed stones, extreme abrasion occurs on the internal walls of the whole pipeline system. Moreover, the elevated temperature of the gas and the aggressiveness of the containing hydrogen sulfide demand an absolutely premium and resistant coating system for the internal lining of the gas conveyor plant.

Ceramic Polymer - coating project in Pakistan

Slug catcher in the “Sawan gas field”, the region of “Sindh” in Pakistan:
12-finger type, pipes with a length of 60 m and a diameter of 1,22 m each

The conveying pipe extends in 12 pipelines in parallel, each with a diameter of 48 inch (1,22 m) and a length of 60 m. In these “fingers“ the volume expands and the gas reduces its velocity. Due to the lightly falling gradient of the pipes, debris and humidity settle in specific inlet and outlet headers and can be removed separately.

Customer: OMV (Pakistan) Exploration, Islamabad-Pakistan
Construction: Descon Engineering Ltd., Lahore-Pakistan
Weight: 1.150 tons
Pressure of the gas: 86 bar up to 129 bar
Temperature of the gas: 55°C up to 110°C

The coating “Proguard CN-1M-LV3” provides durable corrosion protection and abrasion resistance

The internal coating of the huge slug catcher was conducted with the high-solid-product Proguard CN-1M-LV3.

This system shows a high mechanical hardness and an excellent chemical resistance against the hydrogen sulfide, which is contained in the natural gas.

Proguard CN-1M-LV3 is applied in 2-3 layers with a thickness of only 300 µm each by airless spraying method. Due to the fast curing a smooth construction and production flow is achieved.

The Ceramic Polymer GmbH produces high-quality, solvent-free protective coatings for different kinds of industries. Due to the integration of microscopic ceramic and other special particles, coating systems with outstanding physical properties such as excellent chemical resistances, high temperature stabilities and extreme abrasion resistances are generated.
The Ceramic Polymer coatings are applied directly on the blasted substrate (e.g. steel, stainless steel, concrete) without the previous use of a primer. In this way extreme adhesion is achieved.
The scopes of the Ceramic Polymer coatings are for instance all kinds of storage tanks, pipelines or process vessels for the oil & gas industry as well as different maritime constructions, waste water or drinking water applications.
