Mining solutions

Construtec offers solutions for mining under the CONDUKMIN® brand. We transport mining fluids in a sustainable way, with solutions and products with a long useful life, with a 100% recyclable material such as ductile iron.

Our technical team supports you in the hydraulic design, supply of pipes, accessories and valves to channel mining fluids such as fresh water, process water, tailings and mineral concentrate, as well as construction supervision.

Collection of seawater and surface water

Seawater collection system for desalination plants, surface water collection to the mining operation, highly complex for installation conditions and benefits that are not achievable by other pipes on the market: high pressure, earthquake, unstable terrain …

Our iron pipes are coated with CERAMIC EPOXY of high resistance to abrasion and corrosion, with results backed by tests under ASTM standards. In addition, our range includes high-pressure service pipes up to 2000 psi, flangeless and field-weld-free, thanks to the Lok & Play® system. This allows to offer pipes for:

Process water channeling

Pipelines specialized in the transport of acidic waters and soft waters, with resistance to corrosion from pH 1 to 13.

Tailings pipeline

Pipes, fittings, accessories and valves with extraordinary resistance to abrasion and corrosion, which minimize the costs of transporting the tailings or mining pulp, guaranteeing a long useful life.

Mine pipelines or concentraducts

High pressure pipes for the transport of mineral concentrate by wet route.

Case of success

Abrasion test in copper tailings conduction
Ductile iron pipe with internal concrete coating with aluminous content

Typology

Pressure lines.

Tailings transport.

Lok & Play® technology: joints without welding or flanges.

Internal lining to abrasion and corrosion.

Location

Perú

Length

3.000 m

A field test is carried out for a major mining company in Peru for the transportation of abrasive copper tailings, using ductile iron pipes and fittings in diameter 8 ”with Lok & Play locking union, without flanges or welds, in order to evaluate the wear that occurs in the internal concrete coating of aluminous content as well as the behavior and performance of the bond with this fluid.

The test was initially carried out with 150 m of pipe and later, once the first results were obtained, the supply and installation increased, by another 3,000 m with the implementation of improvements and recommendations proposed by Construtec, reinforcing the weakest areas detected in the pipe line and accessories.

The results obtained showed that the Lok & Play® locking union without welding or flanges had a high constructive performance, easy assembly and disassembly and optimal functionality, so the mechanics used for the line worked effectively, to the satisfaction of the maintenance teams and operations.

Regarding the result obtained in the lining, although it improved the useful life of other materials, which until now were used in this mining company, it gave us a significant loss of internal lining in the pipes and accessories, the results not being completely satisfactory, which led Construtec to research and develop a better performance coating, with greater resistance to abrasion and corrosion than the
tested, resulting in the CONDUKMIN range of products, made of ductile iron with a high abrasion resistance CERAMIC EPOXY ECW coating (SHORE value D 85).
