Steam Fittings

Feb. 7, 2024

What do a gallon of gasoline, a ream of paper, and a can of corn all have in common? Each of these items requires steam for production. From oil, gas, and paper, to food, beverages, and textiles, steam is an important aspect of the manufacturing process for a variety of applications and industries.

History

The first steam engine was developed in England by Thomas Newcomen in 1712. By 1730, steam engines were common in western Europe. They were mainly used in mines to pump out water. 

In 1769, James Watt, a Scottish engineer, made significant improvements to the steam engine, making it more efficient than earlier models in terms of power and fuel consumption. Progress continued with the invention of the first locomotive steam engine in 1802.

The development of the steam engine played a significant role in history by sparking the Industrial Revolution. Semi-automated factories were created and the implementation of coal-fired steam engines on railways and ships expanded international trade.

 

Products Recommended for Steam Service

Although its history dates back hundreds of years, steam is still widely used today. While valves, fittings, and other fluid transfer and control products are useful in a variety of applications, it is important to note that not all products are designed for use with steam. Dixon offers a diverse product range that includes steam-safe products.

Boss® Ground Joint Fittings

boss-ground-joint Application
  • Boss ground joint complete couplings supply a convenient threaded fitting to connect two lengths of hose, or a single length to a female or female threaded outlet
  • Use with Boss clamps
Features
  • The stem part that is clamped to the hose is one-half of the Boss ground joint connection. The Boss ground joint spud part of the coupling serves as the other half and is usually fixed to the equipment. The two halves are connected or disconnected by rotating the wing nut of the spud. When connected they achieve both a mechanical and a pressure seal
  • A leakproof seal forms when the metal head of the stem makes contact with the patented polymer seat in the Boss ground joint spud
  • Easy to seal

Specification

  • Recommended for steam service up to 450°F (232°C)

Boss® Clamps

boss-clamps Application
  • Bolts in Boss clamps are designed to bend as they are tightened. This allows the clamp to conform to the hose's outside diameter (O.D.)
  • Always tighten bolts to their specified torque value
  • Periodic re-tightening of bolts is required due to the “cold flow” phenomenon present in all rubber hose
  • Designed for single use only. Once removed they are to be discarded

Features

  • 2 bolt and 4 bolt
Specifications
  • Recommended for steam service up to 450°F (232°C)

Boss® Crimp Steam Fittings

crimp-boss-steam-fittings Application
  • Safe and reliable steam fittings designed, tested, and Dixon-approved for use with the following steam hoses: Continental Flexsteel® 250, Gates Plant Master® Steam, and Texcel® Tex-Steam
Features
  • NO-skive fitting system for ease of fabricating hose assemblies
  • Bite-the-wire crimp ferrules for long-lasting fitting retention
  • Positive metal-to-polymer seal in ground joint couplings
  • Non-metallic polymer seal resists most chemicals found in manufacturing facilities
  • A leak-proof seal forms when the metal head of the steam makes contact with the patented polymer seat in the spud
Specifications
  • Temperature range: -40°F to 450°F (-40°C to 232°C)
  • Benchmark and ISO 4023/6135 standards
  • Test methodology simulates transfer applications as defined in industrial operations
  • Dixon steam test methodology and parameters available on request
