1,Reliable seal function ,the body seals and under joint is mental to metal to metal and the seal flexible combination of s

Application

HY hydraulic grade hoop designed has characters of opening different size of two sets end this operation could allow HY hydraulic operate classified .the character of operation allows the HY –type hydraulic grade hoop fit to high pitch wells,  horizontal wells classification cementing operation in some application fields. Could be used with tube packer, isolate and selective cementing.

Characteristics :

    1,Reliable seal  function ,the body seals  and  under joint is mental to metal to metal and the seal flexible combination of sealing

2,Short body length , the maximum degree of reduction of full stress

    3,Bypass seals doesn’t change the position during the operation, the greatest reduce the opportunity of seals destroyed

4,The special closure design of bypass hole could save the problem of  turning off liquid compression between close plug and gravity plug 

5,Reliable lock ring design could make bypass hole permanently closed

6,Simple bite lock to prevent the rotating parts when drilled , save the drilling time(drilled to save time)

7,Easy to drill  the minimum volume drill  design  drilled to save time

 8,The all kinds parts of grade hoop don’t exit welding

9,Could provide the high performance steel products and anti-sulfur products

10,Open the pressure can be adjusted assembly , to meet with other hydraulic tools combined

11,A cementing grade hoops to open immediately after the bypass hole

12,Provide a variety of special –type buckle
