Product Description
API standard Non-hinge stop collar, stop collar

Our Puyang Zhongshi Group Co., Ltd is special manufacturer of Non-hinge stop collar, many types of stop collar are available, like stop collar with nails, stop collar with bolts, non-hinged stop collar, hinged stop collar, etc..

This has welded on one side and these premium quality bows have a high restoring force with uniform hardness all over. The slip on centralizers comes with a direct installation pipe meant for slipping on. It has a high tensile strength, absorption shock value and great impact value.
The welded centralizers can never be smooth due to single piece centralizer. The welding can be overlapped or little exposed. This allows friction to fluid while running in the hole but the single piece centralizer has a corner radius that allows the fluid to pass due to low friction. The centre allows special Iron Phosphate which prevents it from getting rust. It is available in all ranges starting from 4½" to 20".
