EN 14800:2007 STANDARD FOR FLEXSIBLE STAINLESS STEEL

HOSE

INSTALLATION OF FLEXIBLE METAL CONNECTIONS FACILITIES WORKING FOR HIGH TEMPERATURE FURNACE In accordance with the European Institute Standards, building systems and Equipment, working with gas in buildings, it is necessary ensure safe operation. In order to avoid omitted elements making up the system gas environment and the interior of buildings is requires connections to be made with flexible metal hose by welding (welding) (EN13133)

Due to the requirement of the standard in the past, when many buildings system for gas in domestic environments were built with rubber hoses (rubber base ). Nowadays it is impossible for such installation without the use of flexible metal hose. Another advantage of the flexible metal hose against rubber hoses is their high thermal, fire resistance and high operational reliability. These features, and many others displaced rubber hoses (EN 13501-1: 2006).

INSTALLATION OF FLEXIBLE METAL CONNECTIONS FACILITIES WORKING FOR HIGH TEMPERATURE FURNACE

WHAT DOES THE STANDART EN 14800:2007 MEAN?

This Standard applies to the installation of gas systems and appliances positioned in residential and commercial buildings and other indoor spaces. To ensure the safety of gas connections for which the use of flexible metal hoses for gas, standard covers materials and test methods for flexible metal hoses. According to this standard, in buildings where the gas pressure in the system is lower than 0.5 bar, flexible metal hoses are suitable for establishing the connection between the system and gas appliances. WHAT YEAR WAS ADOPTED STANDART? Standard EN 14800 was used for the first time in 2007, with the added improvements and development adopted its current form.

In many of the leading countries in Europe this standard EN 14800 is known and implemented.

IN WHAT OTHER COUNTRIES MUST BE USED FOR THIS STANDARD?

Member states of CEN (European Standards Institute) should apply this Standard:

Bulgaria Cyprus Denmark Estonia Finland Iceland Lithuania Luxembourg Malta Norway Slovenia Latvia

Building a safer system for domestic gas appliances, durable and long life standard EN 14800: 2007 is the best and most modern standard for Bulgaria in performing and creating gas systems and links.

STANDARD EN 14800 - FUNCTIONS AND FEATURES PROPERTIES

Flexible metal hoses conforming to standard EN 14800, superior standard gas pipes with: •Flexibility •Endurance •Minimum bending radius •Easy installation •Hygienic •Corrosion resistance Resistance to fire •Reliability •Strength •Traceability

WHAT ARE THE CONSTRUCTIVE IMPROVEMENTS HOSE?

Hoses meeting the requirements of standard EN 14800 have a three-layer structure.

Hose: Flexible Functional AISI stainless steel hose 316L (14404)

Braid: To improve the mechanical properties of flexible metal hose use of coating material stainless steel AISI 304 (1.4301).

PVC: Protective coating to ensure hygienic and easy cleaning external contaminants.

The fittings are made of stainless steel AISI 304 (1.4301).

Nut and PVC coating are marked laser.

PVC coating may be produced in different colors.

WHAT ARE THE CONSTRUCTIVE IMPROVEMENTS TO HOSE?

Hoses meet the requirements of standard EN 14800 have a three-layer structure.

BENEFITS

Only one hose in the world for natural gas, which is welded with laser, called '' Laser Welded ''. With laser technology welding errors which may occur under the influence of the human factor is minimized. Thanks to the innovative technology '' Laser Welding '' ensuring a high level of security against leakage of gas.

BENEFITS

Each product produced by the method '' Laser Marking '' is marked with the desired information. Due to the laser marking, after any accident or disaster occurred and found that it is caused by the product can be identified stages of the production process has been through the product itself.

BENEFITS

Due to the the PVC coating product is over - stylish, hygienic and safer! PVC coating prevents abraznivnite particles contained in detergents. Flame structure protects the pipe when exposed to direct flame and allow to ignite.

AYVAZ - EN 14800 ADVANTAGE OVER ITS COMPETITORS

With an annual production capacity of 20 million meters Ayvaz is the largest manufacturer of flexible metal hose for gas in Europe, conforming to standard EN 14800. As specified in the standard for the manufacturer to ensure compliance with the declared performance of marketed products should be implemented, documented and maintained FIC (Production Control System).

AT WHAT TESTS IS SUBJECTED HOSE EN 14800?

The hose according to EN 14800 tested in the laboratory of AYVAZ, the product is subjected to the following tests:

•Elasticity •Bending •Flexibility •Flammable •High temperature resistance •Corrosion resistance

•Operating temperature •Resistance to impact •Hardness •Torsion

WHAT SHOULD YOU PAY ATTENTION

CE Marking and Labels: • CE mark to the product must be in writing and number. • Font for CE marking shall be in accordance with specified standards. • The year of manufacture, batch and mark the hose must be of nut.

Nonconforming marking

Seal

EN 14800: 2007 standard for seals - they are non-metals. In European countries that use the standard EN 14 800 names with elastomeric sealants. Inconsistent klingerit

WHAT SHOULD YOU PAY ATTENTION?

Nut

• Material type and dimensions of the fittings should not differ, materials used in the product had to be consistent.

Mismatched fittings

WHAT SHOULD YOU PAY ATTENTION?

Braid: •The braiding on the product must be properly allocated. •During the bending of the flexible metal hose, the braiding must not deform. •The wire braid should not be in several layers on a flexible stainless steel hose. Unmatched braid

WHAT SHOULD YOU PAY ATTENTION?
