Five commonly used wellhead tools - Hanger

 

Structure and Principle  The hoisting ring is a specialized wellhead tool used for suspending the hanger during drilling and well repair operations. It must have strong bearing capacity, be resistant to impact, be lightweight, and be safe and reliable. The upper ears of the hoisting ring are attached to the side auxiliary hooks of the large hook, and the lower part is attached to the hanger of the hanger. The connection parts between the hoisting ring, the hanger, and the large hook comply with the provisions of SY5288=2000.

  The hoisting ring is of two types: single-arm and double-arm. The double-arm hoisting ring is commonly used in shallow wells and has a bearing capacity not exceeding 1350kN. The commonly used hoisting rings in drilling and production equipment are DH1350 and SH1350. The single-arm hoisting ring is forged as a whole, and the material is ultra-high strength steel. The double-arm hoisting ring is forged and welded from high-quality alloy steel. Both types of hoisting rings undergo meticulous heat treatment and surface treatment, resulting in high strength and toughness levels.
