    Effective in the removal of construction debris, weld slag, sand, oil, dust, rust and mill scale from critical systems prior to plant start-up. We optimize our steam blows with quality engineering, and by utilizing the best equipment. Determining pipe sizing and design, pipe routing, steam conditions, noise level, thermal cycling, water quenching, and condensate generation are all factors that – with our proper planning – will ensure a successful steam blow operation. WHY PERFORM STEAM BLOWING ?When pipe is fabricated during hot working, a heavy oxide layer forms. This layer is known as mill scale and must be removed from critical systems before putting them into service.The steam blow method is similar to the exhaustive air blow technique, but the boiler is fired to generate the pressurized steam used to clean the steam path. Specialized quick opening valves and a detailed procedure, along with the design of temporary spools, steam quenching devices, silencers, and debris containing equipment are required to perform this service.Dry Silencers are designed to vent up to 900 KPPH of steam while maintaining a 85 dB noise rating or less at 50 ft. from the discharging steam. Other benefits include eliminating or greatly reducing hot water discharge associated with traditional silencers, eliminating fall-out of moisture experience when quenching a traditional steam blow, and reduced equipment requirements and associated construction costs.ANPAM ENGINEERING can engineer and perform several different types of steam blow methods depending on our clients needs. System piping is modeled and analyzed for proper velocities, pressures, and disturbance factors. Modeling the system leads to verifiable results and compliance with all client and OEM specifications.ANPAM ENGINEERING has invested a tremendous amount of time and capital in designing our steam blow equipment to ensure we offer the most effective and safest equipment available to our clients. A strong inventory of equipment is readily available worldwide to serve both small scale and large scale projects.

    We are offering Start-up Vent Silencer made from high-quality raw material. These Start-up Vent Silencers are produced in compliance with the rules and lodes followed in the industry as per the specification. Our vent silencers are used to control the harmful and environmentally unacceptable high-frequency noise while venting the highly pressurized air, nitrogen, natural gas, and other hydrocarbon gases into the atmosphere during the production process in industries.Procedure for sizing Vent Silencers :

    ANAM ENGINEERING’s Acoustics silencers, can size any gas or steam vent application when provided the following data.
    • Vent media (Steam or type of gas)
    • Mass flow (Preferably in pounds per hour or kg per hour)
    • Temperature and pressure of upstream of the control or relief valve
    • Line connection to the vent silencer
    The steam or gas is vented out to the atmosphere through the startup vent valve,

    during startup of boiler. This noise produced due to the pressure variation can be effectively reduced through Startup Vent Silencers. Design of Startup Vent Silencer is very similar to that of Safety Valve Silencer. The inlet pressure of the gas stream is reduced to atmospheric pressure using a diffuser without reducing the exhaust flow rate.

    Product Description :
    Residual media steam or gas is let out to the atmosphere through the Start-up Vent valve, during startup or shutdown of a system. This noise produced due to the pressure gradient can be effectively reduced through ANPAM ENGINEERING’s Startup Vent Silencers. Design of Startup Vent Silencer is very similar to that of Safety Valve Silencer. The inlet pressure of the gas stream is reduced to atmospheric pressure using a diffuser without reducing the exhaust flow rate and causing pressure build-up at the relief valve. The number and size of the diffuser sections depend upon the inlet pressure of the medium and the acoustic requirements. The pressure drop across the diffuser is selected based on the flow conditions of the media to offer a cost-effective silencer design. After the pressure is reduced, the medium is sent through a muffler for better noise performance. Design of our diffuser assembly is in compliance with ASME section 8, Division 1 standards. Depending on the size of the diffuser and the silencer muffler up to 70dB of noise can be reduced. Typical applications for Start-up Vent Silencer include boiler blowdown lines, air compressor vents, and gas plant vents.

    ANPAM ENGINEERING offers an elbow type motor silencer employing aerodynamically designed long radius elbow baffles (CR = 0.5) for maximum attenuation and minimum pressure drop. Motor silencer connections are selected to exactly fit the motor fan inlet diameter and the internal silencer area is matched to the connection area so that there are no changes in air velocity. The fans on TEFC motors can often result in noise levels approaching 95 dBA, which is considered unacceptable in most industrial settings.

    The noise reduction for this line of Motor Silencers is between 15 dBA and 35 dBA for standard sized. Higher noise reduction levels are available.
    Motor Silencer accessories includes :

    Acoustic inlet coversInlet screensSupport legsInspection panelsNoise generated from the electric motor is mainly due to cooling air movement, bearing noise, magnetic noise due to cyclic variation of magnetic forces. Mounting the silencers on ventilation intake & outlet opening reduces the noise considerably. Larger capacity motors tend to emanate noise from the casing due to magnetic forces which may require acoustic hood.
    ANPAM ENGINEERING designed, manufactured and delivered electric motor silencers in the capacity of range of 600 KW to 4500 KW.

    Noise in some safety and control valves generates levels above 150  dBA / dBC, a situation that is a concern for the technical operations and maintenance of the plant. Our silencers reduce the noise generated during atmospheric expansions of steam or gas (vents) during the activation of valves, blowdowns, and ejectors. Noise exposure increasingly limits system and profitability productivity. Silencers are used to reduce noise in safety valves (PSV), Relief Valves (PRV), starter valves, blow valves, blowdowns, ejectors, and discharge tanks.To understand the noise limits or target in sound pressure level.

     represents leading companies in the industry to complete our product line, offering complete solutions for high demanding security industrial installations.Rarely is a more complex fabrication designed that also requires an outstanding corrosion resistant coating both internally and externally.  The owners felt this complex fabrication had to have an extremely corrosion resistant coating due to its location in a coastal chemical plant. Multiple corrosive atmospheres could attack nearly every coating considered.  These large Discharge silencers also had to have a corrosion resistant system that would provide a long corrosion free life.  Hot-dip galvanizing was chosen as the best system. Internal baffles made a coating with any other corrosion protection system nearly impossible.  A full immersion dip in the galvanizing bath provided complete coverage at the most competitive price.Every industry makes use of  Safety Valves to protect systems against overpressure when these safety valves are opened to vent steam, gas  or vapor it  is often accompanied by excessive noise levels. Noise  level  as  high  as  150  to  160  dB (A) are not audible / unacceptable. It will affect the hearing level of employees and complaints may also be received from surrounding residential areas or factories.  ANAM  ENGINEERING’s   Acoustics   Safety   Valve Silencer will reduce such noise  to environmentally acceptable levels.  [Such as 85 dB (A) ] as specified by Indian pollution control boards.The following process values are required to make the appropriate selection.
