VCI Powder provides continuous protection for the interior metal surface of an enclosed system against corrosion. Lay-u, preservation, and mothball applications protect the internal cavities and recesses. The powder prolongs the lifespan of the equipment undergoing hydrostatic testing for storage and shipment. Nox-rust powder ensures that the machinery remains in excellent working condition for immediate restoration of production. It is water-soluble, silica-free, safe, and environmentally friendly and does not contain heavy metals, phosphates or nitrite. The powder can also be applied by sprinkling, dusting or fogging enclosures with a low-pressure air hose or applied as a solution.

VCI Powders are designed to provide interior metal surfaces of enclosed systems with corrosion protection which are often used for:

  • Lay-up, preservation, and mothball applications to protect internal cavities and recesses
  • Preserving equipment that requires hydrostatic testing before shipping and storage
  • In a mothballed facility, the VCI powder keeps machinery in working conditions, so that production can be restored whenever needed

Stream Peak’s VCI Powders are available in:

Nox-Rust VCI Powder 1000SF

The Nox-Rust VCI Powder 1000 SF is designed to protect ferrous metals from corrosion-causing elements. Silica-free and water-soluble, the 1000SF protects equipment during storage, lay-up, and hydrostatic testing. Available in two different forms:

  • Nox-Rust 1000SF Loose Powder

Apply the powder by fogging, dusting, or dissolving it in water to protect metal surfaces. The 1000SF does not require any form of removal before the restart of the protected equipment. The Nox-Rust 1000SF Loose Powder is sold in 5-lb & 25-lb boxes.

  • Nox-Rust 1000SF Pouch Emitter

Each 8″ x 11″ pouch contains Nox-Rust 1000SF powder, capable of protecting up to 900 cubic feet of enclosed space. Place the powder inside boilers, tanks, void spaces inside vessels, turbines, and stream or condensate pipelines. Upon application, the breather polyethene sealed bag then diffuses slowly, protecting ferrous metals of equipment during inactivity, storage, or lay-up over a long duration of time.

  • Silica free
  • Water-soluble
  • Suitable for dry application (dusting and sprinkling)
  • Suitable for wet application (fogging or aqueous application)
  • Pouch emitter placed in spaces (slow diffusion)
  • Protects ferrous metals
  • Protects equipment in storage, during lay-up or hydrostatic testing
Nox-Rust VCI Powder 1000SFG

The Nox-Rust Powder 1000SFG is a finely grounded version of the 1000SF, featuring similar functions. However, unlike the 1000SF, the 1000SFG is ideal for applications where a fine powder is needed.

Nox-Rust VCI Powder 1010SFG

Silica-free and water-soluble, the Nox-Rust VCI Powder 1010 SFG is a finely grounded powder, ideal for ferrous metals. It is also compatible with other metals such as copper, brass, and galvanised steel. It can be used wet or dry. The powder does not require any removal before the restart/usage of the protected equipment.

Nox-Rust VCI Powder 1015

Water-soluble & silica-free, the Nox-Rust VCI Powder 1015 protects ferrous metals in equipment during storage, lay-up, and hydrostatic testing. The Nox-Rust 1015 Pouch Emitter can protect up to 15 cubic feet of exposed metals inside an enclosure. Each pouch emitter eliminates the need to fog or spray powders when such methods of applications are not ideal or not possible.

Application

Apply VCI Powders by dusting, sprinkling, or fogging into enclosed spaces with a low-pressure air hose or dissolve in water. Safe and environmentally friendly, our VCI Powders are free from phosphates, heavy metals, or nitrates. There are two ways to apply VCI Powder as a coating, wet or dry application. For dry application, the anti-corrosion powder can be applied by dusting, fogging, or sprinkling. The powder can later be removed by compressed air or water. For wet application, mix with water and then apply the mixture by either spraying, brushing, or dipping the equipment directly into it. The VCI Powder can be used in:

  • Equipment protection after hydrostatic testing
  • Internal surfaces of compressors, turbines, engines, tanks, boilers, heat exchangers
  • Parts, components, and completed assemblies during
  • Shipping and storage
  • Tubular structures, pipes, and vessels

Water-soluble and silica-free, the VCI Powders are specially designed to protect the interior metal surfaces of enclosed systems such as:

  • Boilers
  • Compressors
  • Drilling equipment
  • Heat exchangers
  • Mining equipment
  • Power generation equipment
  • Turbines
  • Tubes, pipes
