BASALT PIPES AND ELBOW

MDSJ Products made of cast basalt have an almost unlimited service life, are resistant to moisture, acids and alkalis of any concentration, are not subject to corrosion and do not require protective paints and do not lose their useful properties due to atmospheric attacks. Therefore, the use of stone casting is much preferable to special cast iron or steel.

MDSJ Basalt pipes and elbows cannot be used directly in a pipeline capacity; therefore, they are placed in welded or seamless steel pipes. The manufacture of basalt products, including the creation of design documentation, is provided by our company. Cast basalt-lined steel pipes and elbows and plates made of basalt are used as ready-to-use building materials. Cast basalt-lined steel pipes can be made with a flanged connection, designed for flange welding and possibly with a collar.

After measuring the exact length and angles of the pipeline, the designer will offer you absolutely wear-resistant pipes and elbows according to your specific order. MDSJ Basalt pipes and elbows are made by reinforcing thermosetting resin with continuous basalt fibers, which gives the pipe superior strength, corrosion resistance and durability. Basalt pipes have many advantages over traditional pipes made of materials such as concrete or steel:They have a longer service life due to their high resistance to corrosion and mechanical stress. They are lightweight, which makes them easier to handle and install. They have a low coefficient of thermal expansion, which reduces the risk of damage due to temperature changes. They have a smooth inner surface, which reduces friction and allows for better fluid flow. They can be customized to meet specific project requirements such as diameter and length.

Exceptionally high wear resistance.

Unlimited resistance to humidity.

High compressive strength.

Resistance to almost all acids and alkalis.

Completely corrosion resistant.

The right material for the job Basalt is significantly more wear resistant than iron or steel.In fact, over time, as the pipe experiences more friction from the media being conveyed, the coefficient of friction increases, creating even more beneficial flow results.Ready for anything Basalt-lined pipes are perfect for many applications, including slurry lines for all mineral processing and hydraulic conveying. They are typically used for fines conveying.Cast basalt is a versatile, cost-effective, and adaptable lining material that extends equipment life.

Where does it fit best?

  • Pneumatic conveying is a strong option for cement, fly ash, mineral powders, and fragile bulk-solids transfer where closed handling matters.
  • On long routes, multi-turn lines, and silo transfers, it can offer a more compact solution than mechanical conveyors.
  • Where dust control and housekeeping matter, it supports a cleaner process environment.

Selection criteria

  • Particle size, bulk density, abrasiveness, and fragility are core design inputs.
  • Line length, bend count, air velocity, and pressure regime must be assessed together.
  • The choice between dense and dilute phase should balance energy, wear, and product integrity.

Operation and maintenance notes

  • Feed stability, airlock selection, and line build-up behavior should be monitored routinely.
  • Bend wear, plugging tendency, and blower/compressor loading are the main maintenance themes in the field.
  • If velocity is too high, wear rises; if too low, build-up and plugging become more likely.

Frequently Asked Questions

How do you choose between dense and dilute phase?

The decision depends on material sensitivity, line length, wear expectations, and the required transfer regime.

Is pneumatic conveying suitable for every material?

No. Material flow behavior, fragility, and tendency to build up all affect whether pneumatic transport is the right fit.

Which components deserve the closest maintenance attention?

Feed equipment, bends, airlocks, and the blower/compressor package usually need the closest monitoring.
