Introduction

    BS 416 Socket and Spigot Cast Iron Drainage Pipes has long been employed by the building industry as a reliable and inexpensive drainage system.  Comparing with plastic pipes, cast iron is more solid and durable.  Furthermore, because cast iron has excellent noise suppression and fire resistant characteristic, it is every architect's choice for drainage inside the building.  Chung Wing Iron Works' BS416 and other cast iron products were first used in Hong Kong in 1952 at the North Point Healthy Village.  Ever since then, our products have now been used in over hundreds of building and civil projects.  This long history is a testimony to the quality of our products and sign of trust from our satisfying customers.

Manufacturing Process

    Our pipes from DN75 to DN225 are centrifugally cast; molten iron is poured into a spinning metal mold.  DN50 and DN300 pipes are cast using continuous casting machine; molten iron into a metal mold section which moved vertically.   Our pipe fittings are cast using sand mold.

Storage & Handling

          All of our cast iron products should be avoid direct contact with the ground.  Furthermore, whenever it is possible, they should be

covered to prevent any possible damages during storage before installation.

Laying Pipes in Trench

          If the pipes or fittings are needed to be laid in a trench, care should be taken when lowering into a tranch to avoid demaging the

pipes and fittings.  Furthermore, the trench should be clear of any large stones which may cause uneveness of the pipe line and inflict

demages on the pipes and fittings.

Jointing
          Our BS416 pipes and fittings have sockets for jointing by using caulk lead.

Cutting, Drilling, Tapping, and Repairing

          Cast iron has excellent machinability; therefore, our pipes and fittings can be cut, drill or tap.  For cutting, one can use a mechanical

saw, wheel cutter or powered disk cutter.  For drilling, one can use a powered hand drill or bench drill.  For tapping, it is common to use a

tapping saddle.    If a pipe or fitting has minor demage, which does not affect the structural integrety, one can repair it by welding or method approved by consultant engineer.  If there is any questions, one can contact our office for advise.
