API BOWLS
BOTH API spider and API split master bushing have the same inner diameter with of 4”/ft on the diameter tapper. The spider body is made of high quality ally steel and heat-treated especially. The spiders are not so heavy and easy to operate. They are designed and manufactured according to API SPEC 7K standard for drilling and well servicing equipment.
MODEL | TUBULAR OD inch | RATED CAPACITY(short tons) |
8 5/8 API spider | 2 3/8- 8 5/8 | 100 |
9 5/8 API spider | 9 5/8- 10 3/4 | 150 |
ROLLER KELLY BUSHING
Roller kelly bushing is a necessary tool for drilling. It is to drive kelly spinner by matching with master bushing. Through rotating of four rollers, the friction between rollers and kelly pipe is reduced and service life is extended. For different sizes of kelly pipe and hexagonal pipe only need to change corresponding rollers. To connect with rotary table, there are two transmission styles (square and pin). The product is designed and manufactured according to API Spec 7K “Specification for Drill Equipment”.
