ABOUT US

The three major activities of Ricwil (Malaysia) Sdn Bhd are in manufacturing, contracting and

engineering trading.

Incorporated in 1984, Ricwil (Malaysia) Sdn Bhd, with 51% Malaysian Shareholders and balance 49% belonging to Ricwil Japan, is licensed to manufacture preinsulated pipes under the Industrial Co-ordination Act 1975. Currently it is 100% wholly owned by Malaysians.

Competent Japanese engineers in Malaysia trained our local technicians for one and a half years. Presently, Ricwil (Malaysia) Sdn Bhd provides services to Singapore, Indonesia, Nepal, Brunei, Philippines, Middle East, Hong Kong, Taiwan, Myanmar, Vietnam, Combodia, Sri Lanka, Bangladesh and Thailand.

Today, Ricwil’s underground and aboveground preinsulated pipes covering thousand of miles are functioning satisfactory in all areas of work. Through these ensuring years, Ricwil Malaysia has expanded its activities to mechanical contracting and trading, serving both the commercial and process industry sectors.

Having a track record of reliability, Ricwil ensure customer’s requirement are met and perform to their satisfaction. With its integrity proven over the years, Ricwil ensures consistency in its products. Coupled with the willingness and initiative of its workforce, Ricwil seeks to provide a service that surpasses the expectation of its valued customers.

OVERVIEWRigid polyurethane foam systems for pipe insulationRigid polyurethane foam has been used for the insulation and protection of pipes for more than 30 years. It is now more widely used than ever, increasingly displacing alternative materials. One of the most popular areas of use is for district cooling systems, where it is the insulant of first choice for many specifiers. Other common uses are in: 1) On and offshore oil and gas pipelines2) Heating and plumbing services for power stations, chemical plants and refineries3) Dairy industry applications4) District heating systems5) Other special applications i.e. swimming pool pipelines

Polyurethane foam’s popularity is based on its outstanding insulation properties, which prevent heat loss, or alternatively maintain temperatures in cold environments to prevent freezing or cracking. These energy conservation qualities improve the overall cost efficiency of customers’ networks.

Other important characteristics include high mechanical strength, adhesion, flexibility and good flow-ability, necessary for the consistent fill and insulation of pipe sections.

It is a material with a proven track record for reliability, durability and efficiency. Versatility is demonstrated by the ability to insulate over an extremely wide range of temperatures, from the extreme cold of -196°C to the intense heat of more than 150°C.

It is also suitable for applications ranging from small plumbing pipes 10mm in diameter, up to the largest heating pipes with 2,000mm diameters and 250mm of insulation thickness.

Pipe manufacturing techniques for effective insulationThere are two main forms of pipe production techniques; discontinuous and continuous. The method adopted by an individual manufacturer will reflect the particular operations and applications of that company’s business.

Discontinuous pipe manufacturing techniquesDiscontinuous manufacture involves filling of the void between, typically, a steel inner pipe within a high density polyethylene (HDPE) casing pipe. The gaps at both ends of the pre-assembly are sealed with tightly fitting caps equipped with injection and air venting holes. Standard steel pipe lengths for this process are 6 m and 12 m.

Why polyurethane is an excellent insulantRigid polyurethane foam demonstrates versatility both through its physical strengths and mechanical properties. These qualities enable it to be used in a wide variety of multi-functional building products which combine insulation with load-bearing, sealing, impact resistance, weight and space-saving, together with ease of maintenance.

Low thermal conductivity Rigid polyurethane foam has one of the lowest thermal conductivity ratings of any insulant, which allows efficient retention of heat or, alternatively, maintenance of a refrigerated or frozen environment.

StrengthRigid polyurethane foam provides a high level of compression and shear strength, which is bond enhanced by bonding with facing materials such as metal or plasterboard.

ProcessabilityRigid polyurethane foam can be made either under continuous block or batch factory production, or by on-site mixing for spray and injection purposes.

In-situ stabilityRigid polyurethane foam can be used in applications which experience exceptional extremes of temperature, from -200°C to +100°C.

AdhesionDuring the short period between mixing and final curing, rigid polyurethane foam is extremely adhesive, which allows it to bond effectively with a wide range of building facings. The adhesion is so strong that the strength is usually higher than the tensile or shear strength of the foam.

CompatibilityRigid polyurethane foam is compatible with a large number of building facings, including paper, foil, glass fibre, aluminium, plasterboard, plywood and bitumen. These can complement the inherent strengths of the foam, enabling use as semi-structural panels and cladding and allowing foam to accept cosmetic finishes such as plaster to operate effectively as moisture barriers in conditions of high humidity.

Water absorptionThe water vapor permeability of rigid polyurethane foam is low and is enhanced in most building applications by the incorporation of a moisture barrier of polyethylene film or aluminium foil.

Rigid polyurethane foams are usually used at lower thicknesses than other insulants, which means that their heat or fuel contribut ion to a fire is low compared to other, thicker insulating materials. The overall fire performance of an insulation panel can be significantly enhanced by the material that is used to face the panel - for example, steel.

Independently monitored, large-scale tests of buildings incorporating rigid polyurethane and polyisocyanurate (PIR) foam insulation carried out in the USA and Europe have concluded that, properly used, these materials do not add to the severity or serious hazard of fires.

LightnessAt low densities (e.g. 30kg/m3), the volume ofpolyurethane polymer in rigid polyurethane foam is around 3 per cent. The remaining 97 per cent of the foam is gas trapped within the cells, which provides the low thermal conductivity properties.

The lightness of the foam is an important aspect in terms of transportation, handling and ease of installation.

Chemical resistanceRigid polyurethane foam provides excellent resistance to a wide range of chemicals, solvents and oils.

PU FactorPolyurethane is an organic polymer formed by reacting a polyol (an alcohol with more than two reactive hydroxyl groups per molecule) with a diisocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives.

Polyurethanes are flexible foams used in mattresses, chemical-resistant coatings, adhesives and sealants, insulation for buildings and technical applications like heat exchangers, cooling pipes and much more.

The relation between temperature and thermal conductivity is indicated in the diagram below:
