Steel Wire Wound UHMWPE Composite Pipe
cross helically wound steel wires reinforced ultra-high molecular weight polyethylene composite wear-resistant pipe(SRUP)is a composite pipe formed by taking the ultra-high molecular weight polyethylene (UHMWPE) inner pipe as the matrix,using the high-strength steel wire wrapped with adhesive resin as thereinforcementand the high-strength polyethylene as the protective layer. The matrixreinforcement and protective layer are tightly connected with adhesive resinand are formed by melting composite.

Abstract According to the China Federation of Logistics and Purchasing, the China Manufacturing Purchasing Managers Index (PMI) rose to 50.8% in May, marking an increase of 0.2 percentage points compared to the previous month. This suggests continued expansion in the manufacturing sector. Among the key sub-indices, the production index climbed to 53.3%, up 0.7 percentage points from April, reflecting stronger output activity. The new orders index also improved slightly to 51.8%, indicating a modest rise in demand. Meanwhile, the purchase price index surged by 5.0 percentage points to 45.1%, signaling a notable increase in input costs. Out of the 21 manufacturing industries surveyed, 14 reported PMI levels above 50%, showing that the majority of sectors are operating steadily. These figures highlight a positive trend in the Chinese manufacturing landscape, with most industries experiencing growth or stability. The data underscores the resilience of the sector amid ongoing economic challenges.
