According to many customs' feedbacks, we find more than 90% leakages of straight pipes that belong to unilateral leakage. Due to adopting different material and size pipes, the customers need to keep more products in stock. Our company designed Wide-Range Strip Repair Clamp(Patent number: ZL 2015 2 1136082.9 ).It is mainly designed for unilateral leakage, can seal under pressure，break range limit and reduce stock. It has the advantages of flexible, convent and quick install. We adopt lengthen type rubber, break the limit of repairing length and bring the flexible leakage stop condition to customers.
As traditional repair clamp is full surround type, customers have to spend higher cost of full surround type even though meet unilateral leakage.CRK is more flexible, for example when meet the unilateral leakage of DN400 pipe，we only need to spend the cost of DN150-DN200 repair clamp to stop leakage, greatly reduce maintenance costs.
