Erciyas MSCL Pipe & Fittings

Steel pipes are the tried and true option for large scale infrastructure and construction projects such as distribution mains, and other large diameter applications.

Whilst steel pipes are used across a variety of markets, industries and applications, our range of steel pipes from Erciyas are engineered for superior water and wastewater pipelines.

  • Strength and reliability.

  • Proven track record in over 40 countries.

  • Long life expectancy.

  • Suitable for high pressure applications up to 6.8Mpa.

Overview

Clover and Erciyas maintain a higher level of compliance for the manufacturing processes and distribution of steel pipes. Key standards we adhere to in the manufacture of steel pipes for the Australian market include:

  • AS1579:2001 Arc-welded steel pipes and fittings for water and wastewater.
  • AS4321:2001 Polyethylene coatings and linings for pipes and fittings.
  • AS1281:2001 Cement mortar linings of steel pipes and fittings.

The range also offers standard proven polyethylene coated and cement lined pipes with alternate coatings and linings available to suit specific applications.

We also have a diverse range of joints types available: including Cylindrical Push-in (C-Joint & E-Joint), Spherical Push-in Ball Joint and Butt Weld Joint to suit specific applications.

Weld process for spirally wound pipe

Welding is carried out inside and outside via a continuous automatic submerged arc welding process. Welding is carried out to meet the requirements of AS/NZS1554.1 Part 1 Welding of steel structures: Category SP.

Joints

To maintain the integrity of the steel pipeline, the best joint is a welded joint:

  • Standard Joint system (Cylindrical):
    • Allows for easy, fast and clean installation
    • Innovative
    • Single Weld, Seal & Restraint system

Cylindrical C-Joint (Push-in Spigot/Socket)

A cement mortar lined pipe maintains a continuous lining without the need to reinstate the lining to maintain smooth fluid flow. The rubber stopper ensures no damage to cement lining during installation.

  • Easily jointing with single weld
  • No cement lining reinstatement required
  • Maintains smooth internal flow
  • Seal coating available

Cylindrical E-Joint (Push-in Spigot/Socket)

The E-Joint for Polyurethane and Epoxy lined pipe incorporates and innovative weldzone feature that ensures lining integrity is not compromised during welding.

  • Easily jointed with single weld
  • Innovative weld zone to ensure integrity of line system
  • Available for Polyurethane or Epoxy linings

Other Joint types are available to suit your application:

  • Spherical ball joint, angular deflection up to 10° depending on pipe OD.
  • Butt weld joint, for high pressure and larger diameters.
