Aviation Fueling Hose Measures

Handling fuel or chemicals is critical and potentially dangerous. It is important to take into consideration the quality of the materials, tools, and products that will be used in handling these chemicals not only for the handler’s health safety but for the smooth flow of the operation and process as well. When you purchased aviation fueling hoses and you noticed that you received the incorrect size hose assembly, this could lead to additional downtime causing lag in the process and operation workflow. At the very least, you will likely incur a restocking charge and more paperwork in addition to the delay.

The Proper Measure

In order avoid these untimely problems in the operation, learn to identify the Inside Diameter (ID) of the existing aviation fueling and/or defueling hose. The first step is to look at the serial number on the fittings of both end of the hose assembly. Hewitt aviation hoses are marked with either “HH XXXXX” or “HS XXXXX”. If you cannot identify the number, Hewitt, a division of Husky Corporation, is always open for you to call so we can check our records for a copy of the hose certificate. For hoses that are more than 10 years old, serial numbers are usually not available. Follow these assessments on your aviation fuel hose to see if you received the proper size of hose:

For instances where no serial number can be found, use at least two of the following recommended processes to validate the hose ID needed for ordering the correct size hose assembly.

• Check the embedded lay line on the hose. Hewitt aviation hoses show the size in the embedded lay line.

Example: HEWITT AIRCRAFT FUELING HOSE 2 INCH / 50 MM NFPA-407 ……..

• Identify the marks on the ferrules by checking the fittings. Ferrules should have the size markings visible. The list below shows typical markings.

• Measure the Outside Diameter (OD) of the hose at an area that has not seen significant wear. Compare your findings to the chart below. 

 

• Measure the OD of the male pipe thread at its widest point. Compare your findings to either column 1 or 2 of the NPT pipe sizing chart below

By following the methods listed, you can remove the mistakes of ordering the wrong size hose. Calling Hewitt is also an option to address your questions and concerns about aviation fueling products, hoses, and accessories at 800-325-3558.

Bulk Chemical Transfers Made Easy with SGA Loading Arm

When a toxic or explosive chemical is transferred from one container to another, it poses threats to the health of the handlers, safety of the workers, and the environment. Improper handling of hoses made to deliver bulk liquid and gas products to tanker cars, trucks, and vessels is just not an option. For the safety of the people and the preservation of the materials and installations, technology is needed. Fortunately, fueling products called hose loading arms were made to do the job safely and more efficiently.

Roman Selinger SGA Hose Loading Arms

Roman Selinger is a reputable brand in Germany that manufactures products that control and move liquids safely. Its SGA hose loading arm is vital to the aviation industry for the purpose of loading through a hose line between a stationary plant and a mobile unit. The loading arm makes fueling easier and more convenient as the operator doesn’t need to lift the hose. It features a special flexible joint mechanism which ensures that the loading arm radius doesn’t go beyond the minimum safe bending radius of the hose assembly. Other advantages with the use of hose loading arm are lower risk of damage, lower maintenance time, faster transfer rate, minimized operator risk for injuries, minimal effort by the operators, and longer hose life.

Hewitt is the authorized representative for Roman Selinger SGA hose loading arms in the U.S. These loading arms that are individually designed to provide ergonomically optimal handling ensure that your operations run smoothly and efficiently. The RS SGA loading arms along with the topnotch Hewitt assembled hose is the perfect combination for a low cost and low maintenance loading system. Rely on the SGA Loading Arm to guarantee easy transfer of chemicals in bulk and the safety of your workers and the environment.
