Our staffs and technicians are trained to work in high sour facilities under hard circumstances giving the best quality and taking into consideration that safety is first.

Purchasing

Why ASUT

ASU is charging 5% interest of the Capital price of any wanted tool or equipment taking into consideration that additional charges might be applied including transportation, taxes and commissions.

Delivery in ASU is fast due to the understanding of ASU members of the immature of time in project and for clients.

ASU management has experienced the criticality of the shortage of some equipment's, fitting, hoses and other consumables in Oil and Gas projects during construction and commissioning phases.

Accordingly, ASU is offering oil and gas contractors a rapid procurement procedure with standard prices and rates for any required equipment or material either from local or international market.

Construction Maintenance and Repairing Services

Why ASUT

Delivery in ASU is fast due to the understanding of ASU members of the immature of time in project and for clients.

ASU Crew members are expert in Both rotating and static equipment as well as electrical and instrument complains.

These services include troubleshooting, alignment (laser, dial gauges), mechanical seal and bearing repair and replacement, catalyst loading, chemical and media filling, internals installation, preservation, filter cartridges replacement, suction strainer cleaning and leak testing.

ASU can support in commissioning activities including mechanical run test (MRT), Surge mapping, introducing of sour and sweet gas and different commissioning activities.

Oil Flushing Services

Flow Velocity

When flushing, it should be noted that a turbulent flow regime is necessvary in each section of the sub- system. The flow rate must therefore be calculated on the area giving the lowest Reynolds Number. Flushing will not be successful when flow is predominantly in the laminar region. For pipes when Reynolds Number is less than 2000 the flow is laminar and above 4000 it is turbulent, the intermediate values indicate transitional flow.

A newly constructed system or the one that is already in use requires flushing after breakdown, repair or time-based maintenance to-remove debris such as scales, rust, sand dirt by filtration of lubrication oil, Different methods & techniques are deployed for when and how to perform oil flushing, depending upon practical limitations and overall requirements of individual machines.

A well-planned and well-performed flushing activity offers considerable return on investment.

For the client who has credible maintenance records & demands no tolerance for untimely equipment failure.

A routine filtration and high velocity/hot oil flushing services are a critical part of preventive maintenance of all rotational equipment.

Temperature

Temperature is another important factor to consider during oil flushing operations, the temperature should be kept as high as it is practicable. The fluid temperature should not exceed °60C if it is to be reused; a higher temperature may be used if the oil is to be dumped.

It is important that any change in viscosity due to temperature is substituted into any calculations.

Chemical Cleaning

Why ASUT

RHIP and YKP projects with PDO were the sources of experience for our crews and supervisors in additional to years of experience in different gulf projects.

All ASU methods of statements are prepared by well-trained engineers and supervisors that are familiar with high quality and on the required time frame and good safety records.

Chemical cleaning is usually performed on process piping and equipment to remove deposits like scale, loose rust, waxes, paraffin, oils, dirt or any other foreign materials that could result in operating and maintenance problems.

A newly built or operational plant requires chemical cleaning to remove all the rust to enhance the operation and heat transfer and to avoid any further corrosion in the plant

Chemical Cleaning Pump & Filtration unit

Chemical cleaning can be either operational or post operational

Below are the various Methods of System Cleaning where we can help our client:

Application of Specialist Treatments

Foam pigging Techniques
Preservation and Passivation
Preventing Rust Formulation after Cleaning
Flushing and Blowing of Pipe-work
High Velocity Air or Inert Gas Blowing

Traditional Cleaning

Application of Acids, Surfactants and Heated Fluid Treatments
High Pressure Water Jetting
Internal Pipe-wall and Vessel cleaning using H.P. Water
Specialist Process Cleaning Techniques

High Speed Flushing

Steam blowing

The chemical cleaning parameter as follow:

Used to remove Grease/Oil, Mill-scale and Iron Oxides

Treatment Types vary upon Specification and Objectives

Treatment Components include

Surfactant: Used for Degreasing Pipe work Surface

Inhibitor: Used to Protect the System from Acid Attack

Hydrochloric or Fluoric Acid used for Cleaning/Dissolving Mill-scale and - ron

Further to that, the type & quantity of chemical(s), contact period with the system and overall procedure will be determined on case to case basis and will differ from one system to another.

The method of treatment chosen will be based on system metallurgy, design & operating conditions, extent of contamination & compatibility of chemicals, end users requirements, cost & HSE issues.

Nitrogen Services

Chemical Cleaning Pump & Filtration unit

A homogenous mixture of nitrogen/helium (N2/He) is pumped into the system. A Zone II, sound proof Nitrogen Pump is used to convert liquid nitrogen to gas & pump the gas into the system at various ranges of ow rates, pressure & temperatures. This testing method is considered as the nal & most stringent form of leak detection, as it establishes the integrityof the system being operationally ready by identifying & quantifying leaks with the help of a mass spectrometer. All anged, threaded connections of piping and equipment within the test envelope are subjected to test.

Since Nitrogen is a colorless, odorless, nontoxic, nonreactive and noncorrosive inert gas it can be used for a variety of reasons within oil & gas industry. During startups & shutdowns operations nitrogen is the most preferred gas, Itis used to perform various activities like drying with Nitrogen, Nitrogen purging and packing, Nitrogen blanketing Inerting & Nitrogen pressure testing. Our experienced engineering and sales team will work with you to design customized solution for all of your nitrogen service requirments

Why ASUT

ASU has emerged as one of the leading companies in this segment and maintains an impressive inventory of equipment such as pumps, tanks, vaporisers and other ancillary equipment.

All equipment are certified for both onshore and offshore operations.

ASU provides nitrogen/helium (N2/He) leak testing and other associated nitrogen services on pipeline and process system during pre- commission phase & shut down activty. These services are provided to onshore / offshore installatices.

Salient Features of N2/ He test

A well-planned and well-performed flushing activity offers considerable return on investment.

For the client who has credible maintenance records & demands no tolerance for untimely equipment failure.

A routine filtration and high velocity/hot oil flushing services are a critical part of preventive maintenance of all rotational equipment.

Pipeline Cleaning Services

A crude oil, gas or water transportation pipeline can get blocked over a period of time as it flows various minerals and organic scales along with the product. If the debris or unnecessary components are left unchecked they will internal deposits & build up on the walls of the pipeline & will severely restrict the flow. These deposits can further be the most complex removal and mitigation factor.

A planned cleaning programme for pipelines can prevent the build-up of debris or deposits and thereby help ensure continuous product flow throughout.
