As a evelopment partner we have alreay introuce countless innovative prouct solutions into this market segment. Millions of our metal hoses an expansion joints for gas applications are use throughout Europe; they have proven themselves base on their problem-free an safe operation. Safety an quality In orer to meet these requirements, we have an extensive testing facility with various test evices which correspon with the relevant German an international stanars. Witzenmann gas hoses for connecting to househol gas evices are absolutely resistant to aging an, in contrast to rub- ber hoses, o not have to be replace on a regular basis. Our success in implementing these quality stanars is evience by the certifications our proucts have receive from the most important national an international testing institutes. An ultimately also by the satisfaction of our customers, who helpe us become the European market leaer not just in the gas sector.

other gas hoses stainless steel pressure hoses Gas meter connection hoses Gas house connections, unergroun installation Prouction series LA, RS DIN 3384 Example of use gas meter connection Hyragas meter connecting hoses allow easy an safe connection of gas meters without laborious installation works by solering or weling technology or by means of threae fittings. Particularly uner narrow installation conitions, e.g. in plastic boxes which are common in many European countries, huge cost benefits are achieve in comparison to conventional assemblies. Due to the flexibility of the Hyragas meter connecting hose, require bens can be realize without aitional angular fittings or pipe sections to be bent in avance in narrow places. Hyragas meter connecting hoses are mainly use in nominal iameters 20 or 25, partly with yellow plastic covering. Application example gas house connection Plastic gas lines for house connections may be installe up to the builing. The material transition from plastic to steel, for example, may be protecte against outer impacts by means of stainless steel corrugate hoses. In case the meium-carrying plastic line is amage, gas is prevente from being able to enter the cellar room or to get unerneath the founations. Example of use - unergroun installation House supply lines an connections to the house s inner lines are particularly critical points in gas supply networks. In areas prone to later subsience amages or earthquakes an flooing, or in areas with heavy-loa traffic, there might occur non-calculable plate movement. Due to this, gas pipes installe unergroun are inamissibly subjecte to bening. In extreme cases, this might lea to the gas line breaking. This movement is compensate for by installing flexible HYDRA stainless steel gas hoses, thus essentially increasing the safety of the gas pipe network. wel-on T section main supply line fitting length. 0.995 nominal length house connection line HYDRA flexible connection in gas pipes for unergroun installation Apart from an extensive range of stanar versions, which can be supplie ex stock (types LA230, LA201, LA241), HYDRA metal hoses can be freely assemble with ifferent kin of fittings in any length. The Witzenmann prouct range consists of a wie spectrum of metal hoses from 6 to 150, which are approve by DVGW acc. to DIN 3384 for gas applications up to a nominal pressure of 16 bar. Depening on the application an operation, the hose moels are available with an without braiing. Long service life, simple installation an absolute safety are the main features of HYDRA stainless steel pressure hoses for gas applications.

R R ld R axial expansion joints for gas applications axial expansion joints for gas applications Stock program Properties an fiels of application HYDRA expansion joints for gas applications ensure stressfree an safe pipe installation. They absorb system vibrations an movements an thus protect the piping network against amages. Axial expansion joints for gas applications reuce impact noise transmission via the piping an avoi vibration an oscillation transmission. Sample applications Drying stoves, gas engines, gas control paths: The absorption of thermal expansion ensures the trouble-free operation of machinery Gas supply lines or gas burner supply lines (gas an air): Here, vibration is compensate, ensuring safe an lasting operation Reuction of force an torque transmission in the area of en fittings an technical ata The expansion joint consists of a multilayer stainless steel bellow. Depening on the relevant case of operation, the bellow is available in the stainless steel materials 1.4571, 1.4541 or 1.4404. Assemble with the require connection fittings, the expansion joints are elivere reay to be installe. The stock program consists of axial expansion joints with common en fittings up to nominal iameter 100. Quality HYDRA expansion joints are approve by the DVGW as per DIN EN 30681 for use in the gas area. Millions of these expansion joints have proven their absolute safety an reliability in practice. HYDRA expansion joints as per DIN EN 30681 with DVGW approval are available in the following nominal withs: Axial expansion joints: 15 to 500 Universal expansion joints: 150 to 500 Angular expansion joints: 50 to 500 Lateral expansion joints: 50 to 500 Expansion joint type escription nominal iam.
