Quality & Safety Department  [ Return towards  Services  ]

We provide a wide range of services and equipments to ensure the safety and quality of Gas Distribution Systems:

Base-built and hook-up certification

Continuity Test

We ensure that the assigned inlet matches the desired outlet for the distribution system. This test is highly important if there is a wide range of gases which includes flammable and also corrosive gases.

Pressure/Pressure Decay Test

We find out if gross leak exists and also test the distribution system at a certain relief pressure.

Helium Leak Test

We look for extremely “fine” leaks (< 1 x 10-9 atm cc/sec) in the distribution system and also check for leaks on welds and as well as mechanical connections. 

Particle Test

We certify that the particle count in the distribution system complies with the client’s desired specification.

Moisture Purity Test

We certify that the moisture content in the distribution system complies with the client’s desired specification.

Oxygen Purity Test

We certify that the oxygen content in the distribution system complies with the client’s desired specification.

Surface Finish (RA) Test

We verify that the surface finish of Ultra High Purity Products comply with established SEMI specification.

Quality management

We never compromise with the quality of the service that we provide. This is established through stringent qualification and control of subcontractors employed to carry out all aspects of the work. This includes gas piping welders, electrician, life safety technicians and chemical installation workers.

We also have a strict weld inspection and control system that ensures that all welds meet our strict requirements.

Our quality management includes a set of UHP procedures that is required to be complied by all our workers and sub-contractors. We also provide UHP training to let the workers familiarize with the procedures that they have to follow. With the UHP Procedure, the quality of our workers and also sub-contractors work are ensured.   We conduct incoming Quality Control for all the tubes, valves, fittings and the rest of the components that we use during the certification of your distribution system. This is done in our Class 10 clean room with Class 1 workbenches that is situated in Tuas.

Continuous quality control (CQC) systems

Continuous Quality Control (CQC) systems are used to monitor the purity of the gases in the distribution system. Different customer will have different requirements so we design and build the system accordingly to satisfy the specific customers’ requirements. We also provide expertise recommendations to suit your systems.

Safety management

In SOXAL, safety is a line function and every manager and employee is responsible for their own safety and the work environment. The safety officers’ roles are to assist the respective Project Management Team and Project Manager on the measures to be taken in the interests of safety and health of the employees and contractors at their respective projects. We have implemented the Safety Management System which is in accordance to Code of Practice CP79 and also enforced duties that are in accordance with Factories (Registration and Duties of Safety Officers) Regulations. Contractors are also made responsible for the safety and health at the respective projects sites through regular contractor meetings and safety training and awareness promotion programs.
