Known a s a leader in the industry, the Kingdom has witnessed major developments in the pipeline industry. To meet the demands of the harsh environment and for protection of cross-country and sub-sea oil, water and gas pipelines against corrosion the Al-Qahtani Pipe Coating Terminal was established in 1954. Since those early days when coat and wrap were used, the Company has rapidly moved to new technological advantages available today and has three coating plants in the Kingdom equipped with the latest coating techniques.

Fusion Bonded Epoxy (FBE) Coatings

Fbe coatings, both internal & external, are essentially single layer (thin) coatings. These are designed for corrosion protection on steel substrates (especially pipes & fittings).


Al-Qahtani Pipe Coating is the licensee applicator for specialized coating systems in Saudi Arabia and the Middle East. The high performance coating systems are basically intended for downhole tubular's, OCTG's, pipelines and in-plant piping systems. The comprehensive range of epoxies, phenolic's & urethanes serve a wide range of uses in stringent environments.

Thru-Kote UB connections are also marketed & installed by AQPCT under a license agreement. These are the only weldable connections for surface pipings that help maintain continuous coating integrity after welding.

Cement mortar lining

This type of lining / coating is used for pipelines for potable water.

Double jointing

This process is designed to join two double random length pipes into an 80 LF long double joint. This effectively reduces field welding / x-ray / girth weld coating into half.

Fabrication

Shop welding has advantages over field welding. Spools can be welded and coated in the same location in ideal conditions.

Three Layer (Polyethylene / Polypropylene) Coatings

3 LPE & 3LPP coatings are thick coatings, which not only provide the anti corrosion properties of FBE which is the first layer (primer), but also provides mechanical protection due to the thick layer of either PE or PP. 3LPE is rated for low temperature services, whereas 3LPP is rated for services upto 120? C.

Al-Qahtani Pipe Coating was the first in Saudi Arabia and the Middle East to apply 3 layer polyethylene coating on 80" diameter pipes for a SWCC (Saline Water Conversion Corporation) water pipeline project. It was a technological achievement to be able to perform such a difficult coating on a very large diameter pipe in accordance to stringent specifications. By this success, client's such as SWCC are not relieved of past design constraints and can now design their future projects based on this higher diameter coating capability of AQPCT.

Negative buoyancy Concrete weight coatings

These are essentially applied to add weight to sub sea or subkha pipelines. Weight coatings are normally applied over any type of anti corrosion coatings such as FBE epoxy or coal tar. Can be applied by two different methods, compression coat or impingement.

Applied coatings for heat exchangers, vessels and boilers

Applied on internal and / or external surface of tube bundles, vessels, tanks, etc. This coating prevents fouling & incrustation in the heat exchangers and enhances life of the same. Maintenance / cleaning costs are greatly reduced due to less maintenance requirement.

Custom Coating

Al-Qahtani has the most modern and technically advanced facility for applying External/Internal FBE, high temperature phenolic and other coatings on pipe fittings, pipe spools, valves, vessels, heat exchangers, tanks etc. These are professionally applied by highly skilled personnel to very stringent standards. Girth weld coatings of precoated, prefabricated pipes and fittings are applied in theshop as well as at client jobsites by specially trained people.

Internal Fusion Bonded Epoxy Coating Of Field Girth Welds

Al-Qahtani Pipe Coating Terminal developed the capability to coat the internal girth weld area of the coated pipes from sizes 12.750 inch up to 60 inch diameter. Capabilities can be developed for larger diameters if so required by clients. This service contributes to providing an end-to-end corrosion protection system with fusion bonded epoxy. The most modern internal line travel equipment performs functions of cleaning, vacuuming, coating and video inspection of the girth weld area.

External Fusion Bonded Epoxy Coating Of Field Girthwelds

Al-Qahtani Pipe Coating Terminal also developed the capability to coat the external girth weld area of the coated pipes from sizes 2 inch up to 60 inch diameter. Capabilities can be developed for larger diameters if so required by clients. This service contributes to providing an end-to-end corrosion protection system with fusion bonded epoxy.

Pipeline Rehabilitation

Al-Qahtani Pipe Coating Terminal developed its own spread of line travel equipment for hydroblast cleaning, sand preblasting, grit blasting, spray coating of the external surface of pipe. Pipelines where tape coatings or similar coatings have failed are field rehabilitated while in service or out of service using in-situ techniques to remove failed coatings like tape wraps or other external coatings and reapplied with liquid coatings like coal tar / polyurethane.
