Abstract
Embodiments of the present disclosure include a pig ramp for receiving and supporting a pig in a pig receiver includes a frame portion having an inner diameter, the inner diameter of the ring being larger than an outer diameter of a pig. The pig ramp also includes one or more ramp segments extending longitudinally away from the frame portion, the one or more ramp segments being coupled to a back side of the frame portion at a lower portion and positioned to receive and support the pig when positioned thereon to elevate the pig above a bottom of a tubular.
Claims10
A pig ramp to receive and support a pig in a pig receiver, the pig ramp comprising:
- a frame portion having an inner diameter, the inner diameter being larger than an outer diameter of a pig;
- and
- one or more ramp segments extending longitudinally away from the frame portion, the one or more ramp segments being coupled to a back side of the frame portion at a lower portion and positioned to receive and support the pig when positioned thereon to elevate the pig above a bottom of a tubular, the one or more ramp segments each comprising a first segment, a second segment, and a third segment coaxially arranged and coupled together, the second segment having a transition that positions a third segment surface at a lower elevation than a first segment surface.
A pig ramp to receive and support a pig in a pig receiver, the pig ramp comprising:
- a frame portion having an inner diameter, the inner diameter being larger than an outer diameter of a pig, the frame portion being substantially ring-shaped;
- one or more ramp segments extending longitudinally away from the frame portion, the one or more ramp segments being coupled to a back side of the frame portion at a lower portion and positioned to receive and support the pig when positioned thereon to elevate the pig above a bottom of a tubular;
- one or more holes extending radially inward from an outer diameter of the frame portion;
- and
- one or more fasteners extending through the respective one or more holes to couple a proximal seal to the frame portion.
A pig ramp to receive and support a pig in a pig receiver, the pig ramp comprising:
- a frame portion having an inner diameter, the inner diameter being larger than an outer diameter of a pig;
- one or more ramp segments extending longitudinally away from the frame portion, the one or more ramp segments being coupled to a back side of the frame portion at a lower portion and positioned to receive and support the pig when positioned thereon to elevate the pig above a bottom of a tubular;
- and
- a groove formed along an outer diameter of the frame portion, the groove receiving a seal that extends radially outward from the frame portion and facilitates coupling the frame portion to an inside diameter of the tubular.
