ROTATING JOINTS AND SIPHON SYSTEMS For The Paper Industry w w w . d e u b l i n . c o m

Effective solutions for optimizing paper machine steam systems and dryer sections. As fuel costs rise, paper producers focus on maximizing machine efficiency. Considering that the dryer section is the largest consumer of steam energy in a paper machine – typically accounting for 55% of the total machine energy cost – an optimized steam and condensate system increases production capability and improves machine efficiency, leading to lower drying costs and increased profits. Dryer optimization solutions therefore focus on steam system and condensate removal technologies, encompassing rotating steam...

FSU STEAM JOINT/DELTASINT STATIONARY SIPHON SYSTEM Self-adjusting Seal Cartridge Mating Seal Components Bell Support Vertical Support Curved Stainless Steel Siphon Pipe Optional Sight Glass Journal Flange Working closely with world-class paper manufacturers and machine builders, Deublin revolutionized the paper industry by pioneering stationary siphon technology for removing condensate from high-speed paper machine dryer sections. With more than 17,000 successful installations world-wide, Deublin stationary siphon systems have become the system of choice with many of the world’s most productive...

FSU STEAM JOINT/DELTASINT STATIONARY SIPHON SYSTEM • Immune to centrifugal force effects Unlike a rotating siphon, a stationary siphon is not affected by the centrifugal force of the rotating dryer. It will remove condensate even at a differential pressure of less than 2 psi, without risking • Improved heat profile control for better product quality Picking and related problems can be a result of high differential pressures. When the dryer’s surface is too hot for the moisture content of the sheet, it flashes – then picks, drags and flutters out of control. Eliminating the need for high differential...

H SERIES STEAM JOINT H SERIES STEAM AND HOT OIL UNIONS The H Series is Deublin’s most popular self-supported rotating pressure joint, engineered specifically for steam and hot oil applications common in the paper, plastic and textile industries. Especially suited for open gear machines, where external mounting surfaces are not available, the self-supporting design of the H Series features two widely-spaced, self-aligning carbon graphite bearings that distribute the load more evenly, reducing wear and promoting longer seal life. The high nickel and chromium content of the Ni-Resist seals provides...

ROTATING/STATIONARY SIPHONS SL STATIONARY SIPHONS FOR SPEEDS UP TO 700 MPM (2300 FPM) The SLTM is designed for low-speed open gear machines in which the typical condensate behavior is puddling or light cascading. The system is installed inside the dryer (thus requiring manhole access to the dryer cylinder) using a head-mounted spider support, which utilizes an internal bushing to buttress the horizontal siphon pipe. The vertical pipe is joined by means of a heavy-duty reinforced 90° elbow that provides additional rigidity. Typical installation of SL Stationary Siphon. The special pick-up shoe...

STEAM JOINTS FSB SERIES STEAM JOINTS Pioneered by Deublin, the FSBTM is a self-supported steam joint that features ball bearings and a balanced mechanical seal applicable to (in tandem with a stationary siphon) high-speed open gear machines. With the FSB, many older open gear machines may now be upgraded to utilize stationary siphons that offer the benefits of reduced differential pressure and blow-through. When teamed up with a stationary siphon, the FSB Series steam joint offers an opportunity to increase production on dryer limited machines while reducing downtime and maintenance costs. The...

STEAM JOINTS DMS SERIES STEAM JOINTS The DMSTM Series rotating joint has dual seal assemblies in which the seal ring is attached to the rotor, which is bolted to the rotating journal. The seal ring contacts the counter seal attached to the stationary joint body, which is rigidly secured to the machine frame by an external support and remains fixed throughout the life of the seal. The DMS also features balanced mechanical seals that operate with reduced contact pressure at the seal faces. This reduces wear and extends seal life. Seal wear is fully compensated automatically through designed axial...

COOLING APPLICATIONS F SERIES COOLING SYSTEM JOINTS The F Series joints feature a self-supported design. Its rotor is attached by a flange to the rotating cylinder journal, while the joint body is attached to stationary inlet and outlet piping. Two ball bearings support the rotor and allow it to rotate within the joint body. OPERATING DATA MAX PRESSURE MAX TEMPERATURE MAX SPEED A bell-supported version is also available. SIPHONS FOR COOLING AND SWING CYLINDERS The cooling cylinder must reduce the sheet temperature uniformly across the web. To ensure uniform heat reduction, an effective cooling...

CALENDER JOINTS 6000 SERIES Cartridge Water Unions The 6000 Series joint is a self-supported design with the rotor attached to the rotating cylinder by means of a heavy-duty flange, while the joint body is attached to stationary inlet and outlet piping. Dual ball bearings support the housing and allow the rotor to rotate within the joint body, which remains fixed. Sealing is provided by a mechanical seal which uses a flat-faced Carbon Graphite (standard) or Silicon Carbide (ELS) steel-banded floating seal ring that mates against a Tungsten Carbide seal ring face. The 6000 uses a balanced mechanical...
