Pig launchers and receivers for oil and gas pipeline cleaning devices are intended to construct stationary and temporary launchers and receivers for pigs, diagnostics, sealing and separation devices in linear sections of oil and gas lines along with looping and/ or oil and gas line branches.
Launchers and receivers are manufactured with DN up to 1400 inclusive and rated for nominal pressure up to 16 MPa.
By design, launcher or receiver is comprised with two cylindrical casings: one with diameter equal to main line (nominal part) and another with larger diameter (extended part) – connected with eccentric or concentric adapter fitting and installed on supports.
To ensure repaid opening/ closure and access to internals, launchers or receivers have quick-release end gates.
Depending on design, there are the following kinds of scope of supply for launchers or receivers:
- separate (no extra equipment in scope),
- packaged where we may offer kicking device, tray, hoist with roping assembly and tailor maintenance platforms, or
- portable launcher / receiver (installed on common baseframe with bypass line, piping, gas sampler assembly, hoist and roping system fixed on the housing or basefarame, pig kicker (for launchers), tray (for receiers) and (if needed) a tray and set of maintenance platforms.
The design service life of launchers and receivers is 30 years.
