DMD (16-48″)

DMDdrawing_24 pipeline pig apache pipeline products

Looking for more effective cleaning and sealing capacity? Then look no further than the Series DMD. Every pig in the series is equipped with two sealing discs and two Series M Cups. These multiple sealing components create a positive seal between dissimilar fluids, while simultaneously providing a bigger surface area. As a result, its sealing capacity, scraping capability, and overall cleaning ability is greatly improved.

Designed to negotiate 1.5D bends, the Series DMD pig moves reliably through piping systems.

Features & Benefits:

  • The DMD pig is configured to offer a sealing arrangement that is used to separate dissimilar fluids, and to lightly scrape pipelines during longer distance operations.
  • Given that anomalies are a fairly common feature of a pipeline scheduled for maintenance, it’s reassuring that pigs mounted with conical cups can traverse pipeline anomalies of up to 20% without damaging essential inline auxiliary equipment.
  • Every Series DMD pig is equipped with Apache Series M cups. As with all of Apache products, the Series M cup was especially developed to perform efficiently and reliably. To maximize durability, it’s made from Reliathane, Apache’s special blend of wear-resistant polyurethane.
  • Every Apache DMD 16”- 48” pig is manufactured with by-pass ports. These ports feature threaded plugs that can be removed, should by-pass be required. By removing the by-pass plugs, a portion of product flow is redirected through these openings. The debris is suspended in the turbulent flow and transferred ahead of the pig.
  • Standard bumper noses cushion the pig and in-line auxiliary equipment, preventing damage.
  • To use a Series DMD pig for different applications, cups can simply be added or reconfigured.

Options Available:

  • Circular flange brushes in the following types and trim materials:
    1. Trim types – flat wire or pencil.
    2. Trim material – carbon steel, stainless steel, plastic or tin-coated.
  • Aluminum or steel gauge plates in slotted or standard styles.
  • Transmitter housing to accommodate electronic tracking equipment.
  • Magnets can be used to either collect ferrous and other construction debris, or they can be used to provide a change in magnetic field required by non-intrusive pig signaler detection devices.
  • CARVER discs.
  • Rattlers.
