Pigging systems with a difference! Customers associate AWH's products with being innovative, modern and cost-effective. To AWH, optimum quality is not a question of price. AWH is not engaged in plant construction. This allows our partners, namely plant manufacturers, to discuss their projects openly with AWH at any time. The experience gained by AWH in the use of pig products is channelled directly into their further development. As a partner you can rely on us. This quality is naturally also evident in pigging products that are required at short notice. Achieving success together in our...

Technical Details Pigging Technology Pigging is a displacement technology that is used for completely emptying pipelines. The pig is a displacer that fits the pipe accurately. It travels through the pipe and pushes the content in front of it. The pig is driven with external power. The drive medium can be a gas (compressed air, nitrogen, etc.), a liquid (water, solvent, etc.) or a secondary product. In an open pigging system the pig is inserted at the sending station and removed at the receiving station. In an enclosed pigging system the pig oscillates backwards and forwards between the...

Technical Information Pig Pipelines and Installation Guidelines Pipes, full Passage The pig is an elastic, solid body with low adaptability. The piggable pipeline must therefore exhibit the same circular cross section throughout. Reductions are not permitted. AWH tolerance for the inner diameter: ± 0.5 % of the nominal diameter AWH tolerance for the ovality of the pipe: ± 0.5 % of the nominal diameter Pipe standards We recommend longitudinally welded pipes with seam smoothing according to DIN EN 10357, series A with internal roughness Ra < 0.8 μm on the longitudinal seam Ra < 1.6 μm. Also...

Technical Information Pig Pipelines and Installation Guidelines T-branches Pigs with at least 2 sealing lips run over T-branches. The distance between the lips must be greater than the diameter of the branch, otherwise the drive medium will pass over the pig and to the front. A longitudinal guide on the branch prevents the pig from falling into a “hole” when travelling. AWH tangent pig: AWH lip pig: Branch NS = pipe NS Branch NS = one NS smaller than the pipe NS Pipeline length The length of the pig pipeline is not restricted. Hoses Hoses are piggable with AWH pigs if they: - have the same...

Technical Information Pig Dynamics Leakage Pigs are tight-fitting and squeeze through the pipe. They seal off the pipe securely on a straight stretch. Leakage can be caused when travelling around a bend depending on the shape of the pig. The tangent pig from AWH features a spherical segment that seals off the pipe reliably at a bend. Service life The friction that develops between the pig and the pipe wall results in gradual wear. This depends on the operating conditions and the “lubricating properties” of the product. When operated properly and used with non-lubricating media, AWH pigs...

Technical Information Pig Dynamics Gaseous drive media The pigging operation can be significantly disrupted as the pig pipeline stores the compressed propellant gas. The most common control errors include: - driving with constant pressure The propellant gas escapes from a fixed pressure regulator. The pig is accelerated over the entire run length and ultimately reaches an uncontrollably high speed. - driving with insufficient flow rates The propellant gas escapes from a pressure regulator, whose standard flow rate is too low to maintain the driving pressure in the pig pipeline. This results...

Technical Information Pig Dynamics Dissipation of driving pressure When the pigging process has been conducted it leaves behind an excess of driving pressure in the pipeline, which has to be dissipated. The frequently practised, sudden release of pressure is only acceptable for propellant liquids. When using compressible propellant gases it is better to gradually dissipate the exhaust gas via a throttle valve and to extract any entrained fluid residues in a downstream separator. The advantages of this method are: - gentle dissipation of driving pressure - low noise level - unpressurised...

Technical Information AWH Pig Components The main fields of application for AWH pigging systems are: - product ejection to increase the yield - product separation to prevent mixed phases - gas ejection for venting and bubble-free filling processes AWH offers a tried and tested modular programme for pigging technology. This includes: - pig components DN25 - DN100 - chamber fittings that are free of dead space for low cost applications - mechanical drive controllers for constant pig speeds - compact cyclones for gradual dissipation of driving pressure - non-contact pig location through the...
