Choke and Kill Rubber Hose

Our choke and kill rubber hoses are especially designed for transporting acid medium and exerting pressure, passing performance test of Clause 9.14.12, API 16C. The framework is made of high strength steel wire rope. The inner liner adopts stainless steel spiral cover. Nylon canvas is used both in the inner liner and in the outer protection layer. As a key part, the seal layer of our choke rubber hoses utilizes a king of special synthetic chemical material which is hydrothion resisting. Furthermore, the external part of choke hose is fireproofing. If there is a need for powerful protection, we can add one more stainless steel spiral cover outside.

As an important part of the choke and kill system, this type is applied to resist spurt in well drilling on ground or underwater.
1. When it is infeasible to adopt normal cycle with drill string, API 16C kill rubber hose is used to pump fluid into the rockshaft.
2. When stratum liquid pool into the rockshaft and formulate a rush of blowout, we can use API 16C choke and kill hoses to exert back pressure to the stratum.
3. It can also be adopted to transport acid medium.
