FIELD: oil, gas and coke-chemical industries.
SUBSTANCE: invention relates to oil and gas industry, mainly to production equipment, namely to design of well completion equipment, which is installed in well after drilling, wherein completion includes filters, packers, suspensions and other equipment. Fixation of elements on pipe used in production of components of well completion equipment includes lower clamping ring and upper fixing ring. Fixation ring is ring with minimum inner diameter smaller than outer diameter at clamping ring in free state, and clamping ring is made with possibility of reduction of diameter when fixing ring is put on it.
EFFECT: higher force required to break the attachment, higher strength at bending loads, easier completion.
