As a manufacturer of a variety of Drilling Elevators, we thought that it might be helpful to share with you everything that we think you might want to know about Single Joint SJ Series Drilling Elevators.
This center-latch elevator which hangs from a swivel suspension assembly, is used to replace unsafe rope slings for hoisting collar-type pipe into position. Its design helps crews to handle pipe properly, avoid damaging pipe threads, and when used properly—can significantly reduce accident and injury.
The elevator’s latch system consists of a latch that locks as the elevator is closed and a latch lock pin affixed to the elevator, that when engaged assists with preventing the latch from opening.
To ensure that you are receiving a quality elevator it is highly recommended that you only buy API certified equipment. The American Petroleum Institute (API) licenses “Drilling and Production Hoisting Equipment” manufacturers under API Spec 8C, which covers elevator links, tubing and drill pipe elevators, sucker rod elevators, spiders (if capable of being used as elevators) and various other types of handling tools.
API is a globally recognized certification and licensing leader in various industries, and also has extensive experience licensing and certifying regular elevators as well. Any manufacturer with the API seal of approval is compliant with API standards and has the proven capability to manufacture to API Product Specification Requirements.
Purchasing equipment from a supplier with API Certification ensures you are buying quality equipment that meets API industry standards.
Of all the tools on a drilling rig, elevators are one of the most stressed pieces of equipment. Due to this, they require regular inspection. KET's operation manual lays out the necessary inspections that must be performed for optimum performance.
There are 2 types of inspections the MRA and TMA Operating manual advise--daily inspections and inspections every 6 months.
**When greasing of pins make sure to pump grease until it comes out of both ends.**
We recommend to maintain the elevator as prescribed below in the periodic Actions/Examinations chart.
Every 6 months a full NDT (Non-Destructive Testing) inspection of all primary-load carrying components should be performed as defined by the manufacture, in addition to the daily checks specified above.
Only KET manufactured parts should be used on KET Elevators.
Upon noticing damaged parts, you should contact Keystone to talk with a sales rep. to discuss and order the proper parts.
It is important to remember that a simple routine visual inspection can end up saving your rig hundreds of thousands of dollars throughout its lifetime, and most importantly help you to keep your team safe.
The purpose of re-certification is to verify and document that the equipment's condition and properties are congruent with API 8B Standards. The standards stipulate the acceptable tolerances of critical components, as well as the criteria for its proper performance.
The verification process documents the steps performed to re-certify the equipment. This documentation shows specific load tests performed and the results of these tests, ensuring your elevator performs according to API Standards.
Re-certifying your elevator is necessary to guarantee it is operating correctly.
This ensures the continuity of your daily operations and employee safety, but it can also assist you in preventing legal prosecution in case of an accident.
Contact KET to see about re-certifying your elevator and to get their recommended re-certification timeline and the details regarding the process.
