Chemical, PVC & Process Lines

Melbourne

Installation, repair and replacement of chemical dosing lines and PVC, ABS and other process pipework for industrial plants. Correct materials, proper supports and tested joints.

Chemical, PVC and Process Pipework for Industrial Plants

Process lines carry the chemicals, treated water and product that production depends on. A failed joint on a dosing line can stop a process, damage equipment and create a safety incident. Choosing the wrong pipe material for a chemical or temperature leads to early failure.

SWR Plumbing installs and maintains chemical, PVC and process lines in industrial plants across Melbourne. We work from the site’s specifications and chemical data, select compatible materials and install pipework that is supported, labelled and tested before it goes into service.

Process Piping Services

  • Chemical dosing lines: supply and replacement of dosing lines, valves and injection points.
  • PVC and ABS process pipework: solvent welded systems for water treatment, chemical transfer and process water.
  • Plant room piping: pump sets, manifolds, filters and valve assemblies.
  • Process water and recycled water lines: supply, return and reuse lines within the plant.
  • Repairs and modifications: leak repairs, reroutes for new equipment and removal of redundant lines.
  • Supports and labelling: pipe supports at correct spacings and line identification so the system is safe to maintain.

Materials, Supports and Testing

Most process piping failures come down to three things: the wrong material, poor support or a bad joint. We check chemical compatibility, temperature and pressure before selecting pipe and fittings, and follow manufacturers’ jointing procedures.

Plastic pipe expands, sags and stresses fittings if it is not supported correctly, especially near pumps and on long horizontal runs. We install supports at the right spacings, allow for expansion and isolate vibration where needed.

New and modified lines are pressure tested before commissioning. Where work involves hazardous chemicals, we work to your site’s safety procedures, isolations and PPE requirements. Larger replacements are planned for a shutdown.

  • Industrial experience: process and chemical lines in operating recycling and manufacturing plants.
  • Careful with chemicals: isolation, flushing and PPE managed to site rules.
  • Tested before handover: pressure tested and documented.
  • Licensed and insured: with contractor documentation supplied for onboarding.

Process Piping FAQs

Which pipe materials do you work with?

Mainly PVC, ABS, polyethylene, copper and stainless steel, depending on the chemical, temperature and pressure. We confirm compatibility against your specification or chemical data.

Can you replace a dosing line while the plant is running?

Often yes, if the line can be isolated and bypassed. Where it cannot, we schedule the work with your team for a planned stop.

Do you pressure test new process lines?

Yes. New and modified lines are pressure tested before going into service and results are recorded.

How much does process piping work cost?

It depends on the material, length, fittings and access. We quote fixed prices for defined scopes after a site measure.

Do you follow our site chemical safety procedures?

Yes. We work under your permit system, isolation procedures and PPE requirements, and supply SWMS for the work.
