Hume: Concrete Pipe

COMPANY BACKGROUND

Hume Industries (M) Berhad, formerly known as Hume Far East Ltd., set up its first precast concrete factory in Prai, Malaysia back in 1929. From this humble beginning, Hume has grown to be the premier manufacturer of precast concrete products in Malaysia with five factories strategically located around the country. It is Hume's firm belief and commitment towards R&D and its foresight in forging strategic alliances that have made Hume the leader in the precast concrete industry today.

In 1961, Hume Industries (M) Berhad was incorporated and became one of the very first companies to be listed on the Kuala Lumpur Stock Exchange in 1963. Hume was subsequently acquired by the Hong Leong Group (Malaysia) in 1982.

Hume has a network of well equipped factories strategically located throughout Malaysia. Hume factories are located in Prai (Northern Region), Beranang (Central Region), Pasir Gudang (Southern Region), Kuantan (Eastern Region) and Kota Kinabalu in Sabah.

Our years of involved in the precast concrete industry has resulted in an extensive network of distribution and comprehensive understanding of the industry, enabling us to meet our customers' needs promptly and efficiently.

MANUFACTURING PROCESSIn our quest to serve our valued customers efficiently, Hume has adopted various concrete pipe manufacturing processes which are briefly described below:

CENTRIFUGAL SPINNING PROCESSThe centrifugal spinning process was invented by Hume in Australia. It has since been adopted by many manufacturers in many parts of the world. By combining centrifugal force and vibration to spin pipes horizontally, the compaction of concrete is achieved.

Pipes with diameters ranging from 450mm to 1950mm are being produced using this process.

VERTICAL CASTING PROCESSIn recent years, Hume has also adopted vertical casting process in manufacturing concrete pipes which can be classified broadly into two sub-categories:

i. Dry cast process

By using the principle of core vibration to vibrate concrete and hydraulic compaction to form close tolerance joint profiles, pipes are produced vertically at various machine stations using low slump concrete.

Pipes produced using this process are marketed under the following names :l VIHY pipes

The diameter range is from 150mm to 450mm for both normal drainage pipes and porous pipes as well.

l Vertical cast pipes (VCP pipes) The diameter range is from 450mm to 1800mm for RRJ pipes.

ii. Wet cast process By using the principle of outer form vibration to compact concrete, pipes are being produced vertically with individual mould sets using high slump concrete, Pipes produced using this process are marketed under the name of LDP pipes (Large diameter pipes) with diameter range from 2100mm to 4800mm.

QUALITY CONTROLQuality control of all materials and components in our manufacturing facilities are undoubtedly an essential part of Hume's precast concrete pipes. Manufactured under stringent Quality Control conditions, our pipes are able to comply to the strictest guidelines made by the civil and structural engineering authorities in the country.

The Quality Management System implemented at Hume is designed in accordance to MSISO 9002: 1994 and have undergone numerous third party audits by SIRIM and other independent consultants. It has been upgraded several times to facilitate continuous improvement in our processes in order to meet the relevant requirements and standards.

Incoming raw materials are inspected and tested in accordance to the relevant BS or MS standards to ensure product quality. A supplier development program has been established to ensure consistency of raw materials supplied and this function is being audited from time to time by internal and external auditors.

Load tests are also carried out on specified batches of pipes as stated in our SOPs which conforms to the relevant BS, MS and AS standards.

SELECTION OF CONCRETE PIPES To select the types of concrete pipes for a particular project, the designer must first determine the required pipe diameter and the maximum fill height over the top of the pipe.

Other important factors that need to be considered includes:-

a. Installation condition in trench or under embankment. b. Types of bedding c. Types of fill material d. Superimposed load -Traffic loading

Hume: Concrete Pipe

APPLICATIONSDRAINAGE For normal drainage and culvert application, Hume offers spun and vertical cast pipe in the range of 375mm dia. to 1950mm dia.

Depending on the type of soil bedding and design criteria, both rebated and rubber ring joints are available for selection.

In addition, Hume also produce vihy pipe to meet the demand for drainage pipes in the range of 150mm dia. to 450mm dia.

For larger pipe sizes requirement, Hume has now extended the range of pipes from 2100mm to 4800mm diameter. Besides for application as drainage pipe, these Larger diameter pipes (LDP) can be used in an exceptionally wide variety of situations such as service tunnels, water tanks, storage tanks, silos and pump well.

For special applications and requirements, please consult our sales team.

SUBSOIL DRAINAGE Hume manufactures concrete porous pipes for use in subsoil drainage by using the vertical cast method. The pipes are produced to take a minimum crushing test load of not less than 20.2 kN per metre length of pipe. The pipes are available with rebated (ogee) joints in 150mm and 225mm internal diameter sizes.

Hume: Cocnrete Pipe

APPLICATIONSSEWERAGEHume concrete sewerage pipes are manufactured to provide a corrosion barrier to withstand corrosive attack while maintaining flexibility to withstand decades of severe services.

Advantages :-l Resists hydrogen sulphide and other sewer gases, acids, alkalis and salts. l The interior lining prevents the disintegration of the concrete. l Resistant to wide variety of chemicals. l Unaffected by fungus or bacterial action.l Unaffected by continuous exposure to high humidity or water.

Design and specification Hume sewerage pipes are available in sizes and classes similar to those of culvert and drainage pipes. Hume sewerage pipes come in different categories or protection lining;l Using a 12mm (1/2") thick layer of High Alumina Cement which conforms to the K.L.

City Hall requirements for sewerage pipes.l Using Sulphate Resisting Cement to British Specification BS 4027 - 1966.l For aggressive corrosive conditions, the pipes can be lined internally with a blanket

of PVC sheet. This is the Hume "Plastiline" pipe, which is used extensively in Australia and Singapore.

l Using sacrificial concrete lining of 20mm or 38mm.

Hume sewerage pipes utilize the Rubber Ring Joint for water tightness and protection from the surrounding environment. Other type of joints are not recommended.

Hume: Concrete Pipe

APPLICATIONSJACKING (Drainage & Sewerage) Hume Jacking Pipes permit the installation of pipe culverts for drainage or sewerage purposes under major highways, roads and railway lines without the need for open excavation which invariably disturbs traffic flow. Recommended joint type is that of a butt joint with an external rebate accommodating a steel collar. (see figure)

For sewer lines, Hume Jacking Pipes can be made: 1. with an internal lining of 12mm thick High Alumina Cement 2. from Sulphate Resisting Cement (SRC) 3. with an internal PVC lining (minimum diameter 750mm) 4. with sacrificial concrete lining (20mm or 38mm)

TYPES OF JOINTSSPIGOT & SOCKET JOINTAlso commonly called the Rubber Ring Joint (RRJ). RRJ provides water tightness and protection from the environment, and flexibility in concrete pipelines. A certain degree of linear deflection can be accommodated with this type of joint.

REBATED JOINTAn internal rebated joint is used for pipes of diameters 750mm and above while external rebated joints are used for pipes of diameters 600mm and below.

This is a rigid joint and deflection due to soil settlement occurring after installation may cause cracks in the joint, thus permitting leakage. These joints are not recommended where water tightness is critical.
