For example, depending, at least in part, on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in the singular sense, or can be used to describe a combination of features, structures, or characteristics in the plural sense. Additionally, the term "based on" can be understood as not necessarily intended to convey an exclusive set of factors, but can instead, depending, at least in part, on the context, allow for the presence of other factors that are not necessarily explicitly described.

[0025] As used herein, the term "nominal / nominally" refers to an expected or target value for a characteristic or parameter of a component or process operation set during the design phase of a production or manufacturing process, as well as ranges above and / or below the expected value. Ranges may be due to slight variations in the manufacturing process or tolerances. Indicates a value of a given quantity that may vary based on a particular technology node associated with the subject semiconductor device. Based on a particular technology node, the term "approximately" may indicate a value of a given quantity that varies, for example, within 5%-15% of the value (e.g., ±5%, ±10%, or ±15% of the value).

The outer protective layer 1 prevents bumps and scratches, the inner thermal insulation layer 2 plays a buffering and thermal insulation role, and the inner pipe 3 realizes the main transportation function of the blowout preventer. A closed space is formed by the inner pipe 3 and the inner thermal insulation layer 2, and the closed space is filled with air. The heat conduction capacity between molecules of still air is relatively weak, so it can play a thermal insulation role. In addition, a protrusion 4 is arranged on the outside of the inner pipe 3, which plays a supporting role of the inner thermal insulation layer 2, and a water heat pipe 5 is spirally arranged in the gap of the protrusion 4. The circulating heat pump 14 heats the liquid and circulates the liquid in the water heat pipe 5, which can actively heat the inner pipe 3 and ensure the normal operation of the blowout preventer pipeline in extremely cold weather.
