Pressure Test
Our pressure test ensures pipelines or vessels are leakage free and comply with international safety standards or as per defined specifications. The test involves filling the system with testing medium, which is then pressurized to a specified pressure and hold for a period of duration depending on its standards or specification. All procedures are documented in the operation manual and equipment certificates are included. We provide quick and easy solutions as follows:

Pipeline Services
DTY services pipeline services include pre-commissioning, commissioning, regular maintenance and shutdown services. We understand the criticality of piping to be undertaken and have the following within the scope of works:
Chemical Cleaning
When compared to mechanical cleaning methods, chemical cleaning process reduces downtime, reduce exposure to toxic materials and environmental hazards.
The objective of chemical cleaning is to remove unwanted foreign material inside the pipeline or system. Key concerns are to remove weld scale, grease & oil, mill scale, corrosion products, sand, dirt, temporary protective coatings and other undesirable debris.
We identify the key process equipment and solvents required for the cleaning process based on the type of pipeline or system material being used. Subsequently, we generate the project work scope required to conduct the task with a cost analysis benefit and execution plan
Oil Flushing
The primary objective for oil flushing is to reduce the potential for premature failure.
The process removes contaminants such as water, rust, loose scale, weld slag and dirt from the system with preoperational cleaning method first before processing with oil flushing procedure. Majority of hydraulic system failure relates to improper or poor fluid conditions.
Leak Testing (Nitrogen)
To comply with the stringent safety standards, all leaks need to be located and remedial actions to be arrested.
In order to detect even the smallest leaks, the most effective method is to use Nitrogen as a traceable gas as it is mono-atomic. The fact that it is an inert makes Nitrogen ideal for leak detection purposes as it is not affected by the presence of other gas and contaminants.
In preparation for the test, the flange connections are taped in order to encapsulate the space between the flanges, thus capturing any escaping gas resulting from a leak in the encapsulated space. The nitrogen is injected into the system or installation until the required working pressure is achieved
Hydro jetting
Hydro jetting services which are also known as high pressure water jetting service. The process uses highly pressurized water from 3,000psi to 40,000psi to clean and remove any unwanted construction debris, rust, mill-scale from newly installed pipeline and even cold cut materials in any open or enclosed areas that are difficult to access. At 4,000psi, hydro jetting systems has the power to burst open the toughest blockages and at the same time scours the full diameter of the pipe, flushing debris, leaving a clear surface.
These techniques have been used in practically every industry especially in cleaning of internal and external walls of pipelines, heat exchanger, boiler tubes, air fin coolers, tank, vessel, drainage etc. Hydro jetting cuts away clogs and slugs to prepare surface materials for repainting and removes grease build-up, rust, rubber, chemicals or other heavy build up without causing damage to the surface below it
Pressure Testing (Hydrostatic / Pneumatic)
Pressure testing ensures that pipelines or vessels are leakage free and complies with international safety standards or as per defined specifications.
The test involves filling the system with air, nitrogen, water, glycol or hydraulic oil, which is then pressurized to a specified pressure and hold for a period of duration depending on its standards or specification. The procedures are documented in the operation manual and equipment certificates are included.
Flange Management (Bolt Tensioning and Torqueing)
Specialized bolting equipment used for bolt tensioning and torqueing ensure the correct controlled bolt load are achieved for all bolted joints during construction and for all subsequent maintenance & repair operations.
We provide the following services:
- Full joint survey
- Calculated and Controlled Bolt Tensioning / Torqueing
