Fire Pipe

Fire pipe products are specifically designed for pressure reticulation in fire systems within commercial and industrial buildings. At United Steel, we ensure that our fire pipe products are sourced from top-quality steel manufacturers, adhering to specific safety standards. Our fire pipe products are certified to the ActivFire® scheme, managed by the CSIRO (Commonwealth Scientific and Industrial Research Organisation).

The ActivFire® scheme evaluates and pre-qualifies products for fire protection systems, and all CSIRO-evaluated products are listed on the Register of Fire Protection Equipment. Fire pipe products are commonly identified by their distinctive red paint finish, but they are also available in a galvanized finish. These products are easy to weld and paint, and they are used in closed pipework systems. They are typically suitable for roll groove and threaded jointing products. Please discuss your requirements with the United Steel team. We can supply you with ORRFIRE® pipe products manufactured by Orrcon Steel.
