顶装式气相回收系统
Drylok™ Vapor Recovery Systems by OPW provide
the safest and most efficient solutions available for
the transfer of hazardous liquids and recovery of
potentially hazardous vapors.
OPW Engineered Systems offers two basic top-loading
vapor-recovery designs that can utilize the Drylok™
system over a wide variety of applications. The basic
designs include:
Piggyback Style Arm
This simple design is highly functional. It has a vapor line
welded to the product arm. The versatile arm also can serve
as an unloader by using the “vapor” line to pressurize a
railcar or tank truck equipped with a permanent deep pipe.
Dual Arm / Siamese Configuration
The most widely used vapor-recovery assembly style, this
system features separate arms for product and vapor that
are joined together at the inner boom structure. One of
the more popular variations of this design also has the two
counterbalance swivels and the outer arms joined together
in a side-by-side arrangement to minimize the overall vertical
dimension of the outboard assembly. On most dual-arm
designs, the product line feeds from beneath and the vapor
line from overhead.
whatever additional equipment may be required for your
particular application. Please contact OPW at 1-513-696-1500
with special requirements.
When loading tank trucks and railcars equipped with
permanent product and vapor connections, the end fittings Open Dome Loading
on the loading arm are typically quick- disconnect couplings,
unions, or flanges. The Drylok™ coupler system can be
outfitted for use on dual-arm and Siamese configurations.
OPW Engineered Systems offers a wide variety of vapor-
recovery components for applications where loading
takes place through an open dome. These include cover
plates, tapered hatch plugs/cones and the OPW Inflatable
Special Requirements
Hatch Seal.
OPW Engineered Systems vapor-recovery loading and
unloading solutions can be steam jacketed or traced,
equipped with automatic shut-off controls, or outfitted with
OPW Engineered Systems’ vapor-recovery assemblies are available in 2", 3", 4" and 6".
They also are available in steel, stainless steel, aluminum and specialty alloys.
Please consult the factory with your specifications and OPW Engineered Systems will design a
vapor-recovery loading system to meet your needs.
Hatch Cover Vapor Plates
Hatch cover vapor plates are used to retain and recover harmful vapors
and avoid excessive splashing (especially on tank wash arms). They also are
used to prevent dirt, moisture, insects and foreign objects from entering
the tank.
