How do these spacers provide cathodic protection?

The polyethylene material has low moisture absorption, which helps maintain cathodic protection for the pipeline.

What is the recommended spacing for the spacers?

Use two spacers back to back at the leading edge with 1.5m spacing along the pipe bore.

AI-Powered supplier vetting

SummaryLyfoo Industry Co., Ltd. is a China-based limited company described as both a manufacturer/factory and a comprehensive material-handling enterprise integrating manufacturing and sales. Its reported product scope includes cranes, hoists, lifting equipment, and high-pressure water pumps. The supplier reports ISO 9000 and ISO 9001 certifications, more than 10 production lines, 50 R&D engineers, 50 quality-control staff, and stated annual capacities of 10,000 overhead cranes, 8,000 gantry cranes, and 30,000 wire-rope hoists. It exports to multiple global regions, with exports representing 41%–50% of total sales, and lists collaborations with LUCKY Group and Guoming Ductile Pipe. Evidence is insufficient to confirm after-sales service systems, customization capability, or financial credibility. One recorded transaction is associated with MAXTER DE COLOMBIA S.A.S.

Supplier typeThe supplier is identified as a manufacturer/factory and a limited company, while another record classifies its company nature as a trading company. Its stated business combines manufacturing and sales in material handling, with products including cranes, hoists, and lifting equipment. This supports a manufacturing-oriented supplier profile but also indicates mixed classification across the records.

CertificationsThe supplier explicitly reports holding ISO 9000 and ISO 9001 supplier-management-system certifications. This is direct evidence of formal quality-management certification.

R&D capabilityThe supplier states that it developed multiple high-pressure water pumps ranging from 500 to 40000 bar and reports 50 R&D engineers. These details provide explicit evidence of product-development activity and an identified R&D workforce.

Production capacityThe supplier reports more than 10 production lines, 50 quality-control staff, and 50 R&D engineers. It also states annual capacities of 10,000 overhead cranes, 8,000 gantry cranes, and 30,000 wire-rope hoists, indicating substantial stated production capacity.

Client casesThe supplier reports in-depth international-market collaborations with LUCKY Group and Guoming Ductile Pipe. Separately, one recorded transaction links the supplier to MAXTER DE COLOMBIA S.A.S. in Colombia, but the evidence does not provide project scope, product details, delivery outcomes, or customer references sufficient to evaluate case quality.
