PT. Setia Hati Tekindo one of Corrosion Specialist Company Providing a variety of products Corrosion Monitoring, Chemical, Cathodic Protection, Fitting, Instrumentation, Inspection and Services in various industrial plants specializing in oil and gas processing and petrochemical.
Multiple disc coupon available for pipes with diameters of 6 “or more. This method of protection against corrosion of the pipe offers the following advantages: Inherent orientation parallel to flow, greater area area at a specific level, greater quantity and variety of Coupon materials, easier monitoring in stratified flow or multi-phase flow, and the location of corrosion coupon in the assembly access recreation area for monitoring gas pockets or stagnant areas.
Multiple disc coupon 2″ system can be used to Monitor:
- Top of line
- Middle of line
- Bottom of line

Sacrificial Anodes are highly active metals that are used to prevent a less active material surface from corroding
A simple method of protection connects the metal to be protected to a more easily corroded “sacrificial metal” to act as the anode. The sacrificial metal then corrodes instead of the protected metal. For structures such as long pipelines, where passive galvanic cathodic protection is not adequate, an external DC electrical power source is used to provide sufficient current. Cathodic protection systems protect a wide range of metallic structures in various environments.
Common applications are:
steel water or fuel pipelines and steel storage tanks such as home water heaters; steel pier piles; ship and boat hulls; offshore oil platforms and onshore oil well casings; offshore wind farm foundations and metal reinforcement bars in concrete buildings and structures. Another common application is in galvanized steel, in which a sacrificial coating of zinc on steel parts protects them from rust.
Scale Inhibitor from diphosphonic acid (C2H8O7P2)blended and effective scale inhibitor used to prevent scale formation due to Calcium Carbonate,Magnesium Hydroxide and other common scale forming salts. No maintenance is required in carrying out the addition of this scale inhibitor. Its liquid form makes it convenient to use directly and the dosage level is determined with respect to the properties of the water to be treated.

Spiral wound gaskets is categorized as semi-metallic gasket that is typically used for high pressure applications. The sealing element is formed by winding two materials (one for sealing, one for resilience) into thin v-shaped spirals.
One material used in the sealing element is usually a metal and the other, referred to as a filler, which is a soft nonmetallic material, typically Teflon, aramid fiber or graphite. Both are chosen for compatibility with the sealing media and their ability to withstand the operating conditions. Different configurations exist to handle different flange designs and operating conditions.
These gaskets have good recovery and good tolerance for flange-surface finish irregularities. The sealing action is the result of a combination of the flow of the metal and soft filler plies when the gasket is compressed. They are particularily suited for assemblies subject to extremes in joint relaxation, temperature or pressure cycling, shock, or vibration
