Scaffolding

Scaffolding

Hai Leck is an Approved Scaffold Contractor certified by the Ministry of Manpower. Scaffolds are the primary mode of access in most large structures and are widely used by fellow contractors and plant owners for carrying out work and inspection of new constructions and maintenance works. The two main types of scaffolds that we provide are system scaffolds and tubular scaffolds. We have a sizeable inventory of scaffold materials which has enabled us to take on major construction projects and maintenance contracts in the oil and gas and petrochemical plants.


All our scaffolds are constructed by certified scaffolders under the supervision of our qualified scaffold supervisors and where necessary, certified by our professional engineers to be safe for use in accordance with Singapore Standard, Code of Practice 14: 1996.

Corrosion Prevention

Corrosion Prevention

Hai Leck specializes in corrosion prevention through application of industrial protective coatings. Our corrosion prevention services provide protection for metal structures in the oil and gas and petrochemical plants against oxidisation, erosion and rust which weakens the chemical bond and structural strength of these structures.


Prior to the application of protective coatings, we prepare the surface of the substrates primarily through grit blasting either through automated shot blasting or at site in protective enclosures. The types of protective coatings we offer include various epoxy, zinc silicate, polyurethane, thermally sprayed aluminium and glass fibre lamination.

Thermal Insulation

Thermal Insulation

Thermal insulation refers to methods and processes used mainly for heat transfer. Some of the common insulation materials we apply include calcium silicate, rockwool, pyrogel, cryogel and cellular glass.


In the oil and gas and petrochemical industries, fluids and gases in pipes, vessels and process equipment must be maintained at constant temperatures during the treatment process. Our thermal insulation application is applied to various parts of the oil and gas and petrochemical plants, such as pipes, vessels and process equipment, to reduce the energy needed to maintain the temperature of such fluids and gases, thus saving energy consumption and reducing operating costs.

Refractory

Refractory

Refractories are materials capable of withstanding high temperatures above 800°C and physical wear and corrosion by chemical agents. They are used to line high temperature furnaces, incinerators, reactors and other processing units.


We provide complete refractory packages including design, material procurement, installation, commissioning and maintenance of the refractory linings we supply to our customers.

Passive Fireproofing

Passive Fireproofing

In the oil and gas and petrochemical industries, the most common type of fires encountered is hydrocarbon fires which occur when hydrocarbon chemicals and fuels ignite. We provide passive fireproofing systems designed to restrict the effects of hydrocarbon fires on structures and equipment to protect steel structures and equipment in the event of a fire.
