Before passing on to examine each hose type, please remember that the pressure resistance increases as the rise of the wall thickness and length of the corrugations in contrast, flexibility falls with the rise of these two parameters. Each type of hose produced by Ayvaz is given with the relevant product table. Some values given in these tables can be identified as follows. Operation Pressure: The operation pressure given for the stainless steel in the tables expresses two different pressure values.

1. Permissible Operation Pressure: It is accepted as the pressure value at 20 °C and static loading circumstances with no movement. Safety factor of bursting is 3.

2. Nominal Pressure: It is defined as the maximum permissible pressure value according to DIN 10380. The maximum permissible pressure should meet the safety factor of 4 against bursting and average flexibility of 10.000 load cycles in U-bend.

Following data for the correct design of the hoses are required;

• Nominal Diameter (DN)
• Bending shape
• Minimum and maximum operating pressure
• Temperature range
• Materials

Following additional information help to increase the design quality accordingly;

• Transported fluid
• Maximum permissible pressure
• Maximum permissible temperature
• Length of the hose
• Flow rate
• Fluid movement and vibration type

We see the product quality is the key factor of our company’s success. Ayvaz’s quality management system allows us to keep up with and meet current quality levels, meet the consumer’s requirement for quality, retain employees through competitive compensation programs, and keep up with the latest technology. AYVAZ is permanently monitoring and improving the production quality.
