2, the implementation of standards: Spec 8C API and SY/T5035
3, Type Elevator Slip use of environmental conditions:
1) is allowed to use in the temperature condition of 70 DEG C - 18 DEG under.
2) to meet the harsh conditions of field operation of oil field.
4, slip type elevator works: slip type elevator with center opens the structure form, it is composed of a left main and right main body, a clamp, hinge, hinge axis, lock hook, card page torsion spring, slip body, slip teeth, a pressure spring, a pressure plate, a bolt and other parts.
The left and the right main body are connected by a hinge shaft, and the locking system is composed of a card page, a card page shaft, a lock hook, a locking spring and a lock tongue. When opened, as long as the lock hook pull handle, the locking hook is disengaged from the card page has been torn off. Pull the left and right main handle, open the elevator. Is closed, as long as the left and right handle body together, lock tight system in under the action of the torsion spring automatic elevators shut and locked.
Four pieces of Slip are installed on the main body of the left and the right through the bolt and the pressing spring respectively. Does not work, due to the action of the pressure spring, slip body to move upwards, slip teeth loose, is not working condition; work, the column moves and string collar pressed guide ring, slip slide down along the elevator around inside the body of a cone, move to the certain distance, the slip engaged hold column.
5, selection of materials: the main bearing parts are made of high strength and high strength steel.

9, Type Elevator Slip main quality control requirements:
1) each batch of material and casting of the chemical composition in accordance with the relevant standards.
2) the main bearing part 10% carries on the ray wave flaw detection, the high stress area satisfies the GB/T5677 grade II request, and the rest part meets the GB/T5677.
3) the main bearing mechanical properties of materials: not less than Rm = 860 PMa, RP0.2 = 690, Z = 15%, PMa,
A = 35%, AKV = 42J (- 20 C).
4) Type Elevator Slip size parameters in line with the 8A API specification and SY/T5035 standard requirements.
5) product 1.5 to carry out 100% times to witness the load test.
6) all parts for magnetic particle testing, high stress area to meet the requirements of GB/T9444 I, and the rest of the parts to meet the requirements of the GB/T9444 ii.
7 main bearing parts from raw materials to the use of the whole process of tracing back.
10, Type Elevator Slip maintenance, repair, see the instructions for use.
11, appearance requirements: slip type elevator non processing surface coated with anti rust primer coated with orange paint; machined surface coated with anti rust oil.
12, packaging: the use of wooden packaging.
13, shelf life: one for a period of one year.
