In a desulfurizer production project in Huangshi, Hubei, the company needs to transport the desulfurizer powder through a pipeline system to downstream usage points. This conveying condition features high concentration and high flow rate, placing high demands on the wear resistance of the inner wall of the pipeline. Head Powder Company undertook the pipeline design and supply tasks for this project, providing a wear-resistant conveying solution tailored to the actual site conditions.

Customer Needs and Challenges

The customer encountered severe pipeline wear issues in the original conveying system. Ordinary carbon steel pipes develop partial perforations after about three months of operation, leading to frequent shutdowns for maintenance, which not only increases spare parts replacement costs but also affects production continuity. In addition, the impact angle of desulfurizer powder on pipelines and the uneven distribution of material particle size further exacerbate local wear and make maintenance cycles difficult to predict. The customer urgently needed a more durable piping system to reduce overall O&M costs and improve conveying stability.

Solutions and advantages

Head Powder designed a composite piping system lined with wear-resistant materials based on the customer's site parameters. The pipeline is laminated with a high-hardness wear-resistant layer on the inner wall of the metal base pipe, with a hardness of Mohs grade 7 or above, effectively resisting high-speed erosion of powder particles. By optimizing the curvature radius and lining thickness at the pipe elbow, the impact of materials on the back of the elbow is reduced, resulting in more uniform wear distribution. In practical applications, this wear-resistant piping system has operated for over 12 months without significant thinning, and the replacement cycle has been extended to more than four times that of the original system, reducing maintenance frequency and spare parts expenses for customers. At the same time, Head Powder provides installation guidance and regular inspection services, helping the client establish a scientific pipeline maintenance plan.
