Cast basalt lined steel pipe

The Cast basalt lined products are mainly used for material transportation links and storage equipment linings with heavy wear and corrosion.

Centrifugal casting moulding of cast basalt pipe

Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers. It combines the advantages of cast basalt and steel pipe, wear resistance, corrosion resistance, anti-high-pressure, transportation and easy installation. Water transport in plant ash and metal mine tailings pipeline hydraulic conveyance system applying this product can life up to 30 years. Cast basalt lined steel pipe is divided into straight tube, elbow, tee, reducer pipe.

There are always wear and tear of equipment and materials in industrial production.

With the rapid development of modern industry, the equipment running faster and faster, the wear rate is also faster and more serious. Equipment or material life has become an important factor which restricts enterprises to improve production efficiency.

In most cases, the biggest cost for a company is lost production time due to unplanned downtime. Effective use of suitable wear-resistant materials can reduce the frequency of unexpected shutdowns in the production process, extend production time, and reduce company costs.

According to statistics, each year in metallurgy, mining, electricity, coal industry, because of wear of equipment and materials caused losses amounting to 40 billion.

Although the wear and tear of materials or equipment hardly leads to catastrophic events, the accumulation of energy and material consumption is phenomenal. In many basic industries, material transportation and equipment wear and tear exist simultaneously.
The loss caused by wear and tear is not only the initial equipment investment, but the more serious loss caused by unplanned downtime is the swallowing of corporate assets.

Cast basalt process

The product processed from cast basalt is a new type of silicate crystalline material. Using natural rock (basic database, shale, etc.) or industrial waste as the main raw material components, smelting, casting, heat treatment and other processes are regularly arranged, crystalline, hard, and fine-textured metal industrial materials. Casting basalt has an excellent high abrasion and high resistance. Abrasiveness. Corrosion resistance.

Why Do I Need Wear Parts?

“Wear” is the last thing any business wants to experience with their machines. Apart from its unpleasant physicality, it could also be a sign that means your parts and/or components are about to break. You need wear parts to help prevent or prolong the wearing out of these parts and components – and that could be any type of wear parts such as pipes, liners, plates, etc.

What Kinds of Wear Plates Do You Offer?

Here at Sunny Steel, we put emphasis to the primary kinds and types of wear pipes and fittings – they include:
  • Ceramic Liner pipes and fittings
  • Ceramic tile lined pipes and fittings
  • Ceramic sleeve lined pipes and fittings
  • Cast basalt lined pipes and fittings
All of them have their particular uses, but these cover almost all the materials companies need to work on.

Merits and Salient Features
