SECTION I - GENERAL DESCRIPTION AND CONSTRUCTION

GENERAL DESCRIPTION

This book describes a packaged steam powered water heater that is a stationary, self-contained unit. The complete assembly on a standard unit consists of the storage tank, immersion heating coil, steam regulator, steam drip trap, condensate trap, steam strainer, condensate strainer, vacuum breaker, and an ASME rated combination temperature and pressure safety relief valve. Optional equipment may be supplied with your unit. Please consult the product drawing for details specific to your assembly. The unit is factory assembled, insulated, jacketed, primed, painted, piped, tested, and ready for service connections.

CONSTRUCTION

TANK

Standard Tank Construction:

The standard storage tank is constructed of all welded carbon steel, designed and built in accordance with ASME Section VIII and stamped, certified, and registered with the National Board of Boiler and Pressure Vessel Inspectors. It is internally lined with specially formulated Hydrastone cement to a 5/8- inch minimum thickness for superior protection and tank longevity.

Optional Tank Linings:

1.Phenolic – An epoxy coating applied in two coats to a total thickness of 10-12 mils. Typically used in process applications using low conductivity deionized (DI), distilled, or food grade water.

2.Copper – A 3lb./sq. ft. copper sheet approximately 0.0646-inches thick covers all interior surfaces. All copper sheet seams are factory tested to ensure long lasting protection of the steel vessel.

3.Flame-Spray Copper – Molten copper is sprayed on the interior surfaces to a thickness of 5-6 mils. The copper bonds to the steel, and an additional overcoat of Phenolic lining is applied on the copper to seal all pores.

4.Galvanizing – The steel pressure vessel is pickled and hot dipped in molten zinc to create a barrier which internally and externally protects the steel vessel for cold and hot water storage.

Optional Non-Ferrous Tank Materials:

1.Copper-Silicon – A copper-silicon alloy offers tremendous tank longevity due to its ability to withstand the cycling effects induced from changes in water temperature and pressure. This material is suitable for storage of hot potable water in a variety of commercial and industrial applications.

2.90/10 Copper-Nickel – A 90% copper and 10% nickel alloy similar to copper-silicon, but with added strength and corrosion resistance. Typically used in applications with corrosive environments (salt water) or critical applications.

STH, ST specifications

Hubbell ST and STH connectors are pivotal components in the realm of power and data transmission. Known for their durability and reliability, these connectors are widely implemented in both commercial and industrial applications. Their design caters to the need for efficient connectivity while ensuring safety and performance.

The Hubbell ST connector is engineered with a robust, user-friendly configuration that allows for quick and simple installations. It features a bayonet-style coupling mechanism, which ensures that the connection is secure and resistant to accidental disconnection. This design is especially beneficial in high-vibration environments, making it ideal for use in various industries, including telecommunications, aerospace, and manufacturing.

On the other hand, the STH connector is specifically designed for high-temperature applications and environments where harsh conditions prevail. It is made from high-temperature materials that can withstand significant thermal stress, thus ensuring consistent performance even in challenging conditions. This feature is particularly crucial for industries such as oil and gas, renewable energy, and any sector that relies on high-performance machinery.

Both ST and STH connectors utilize advanced technologies to enhance their performance. They incorporate precision-engineered contact surfaces that allow for optimal electrical flow, while minimizing signal loss. This is especially important in data-intensive industries where maintaining signal integrity is critical. Additionally, these connectors feature insulation systems that provide protection against moisture, dust, and other environmental factors, significantly prolonging their lifespan.

One of the standout characteristics of Hubbell connectors is their versatility. They come in various configurations and sizes, allowing them to cater to a wide range of applications, from telecommunications to industrial machinery. The connectors can handle different voltage levels and current ratings, thus accommodating the requirements of diverse operational setups.

In conclusion, Hubbell ST and STH connectors represent reliability and functionality in connectivity solutions. Their robust construction, advanced technologies, and adaptability make them a top choice for professionals looking for efficient and dependable connectors in demanding environments. Whether it’s ensuring seamless data transmission or providing power to critical systems, Hubbell connectors stand out as a preferred solution across many industries.
