This standard is revised on the basis of SY/T5110-93 casing scrapers. In this revision, the following contents have been modified, deleted and supplemented 1. The original standard Chapter 3 "Type, Model, Series and Basic Parameters" was changed to "Classification and Model", and the basic parameters were put into the technical requirements.
2. The mechanical properties of some metal parts materials were modified by the factory. 3. The performance of the rubber cylinder material has been redefined. 4. The reference to "General Technical Conditions for Oil Drilling Machinery Products" has been deleted. 5. The commitment to users in Article 7.5 of the original standard has been deleted. 6. The judgment rules for factory inspection and type inspection have been supplemented. 7. The life requirements of the cutter body have been supplemented.
This standard replaces SY/1 5110-93 from the date of entry into force. This standard is proposed and managed by the National Technical Committee for Standardization of Oil Drilling Equipment and Tools. The drafting unit of this standard: Tonghua Oil Tools Co., Ltd. The main drafters of this standard are Tu Limei, Chen Min, and Li Dongxing. This standard was first issued as a professional standard ZB/TE92010-89 in July 1989. It was confirmed through review in 1993 and changed from ZB/TE92010-89 to SY/T 5110-93. This is the first revision. 1 Scope
