37° JIC Flare Fittings

Stainless steel flare fittings are used in areas where strong vibrations, high pressure peaks and high mechanical loads occur. Flare fittings guarantee a high level of safety in the pipe system. The main areas of application include shipbuilding, mechanical engineering, the petrochemical, offshore, paper and hydraulics industries.

Important information on technical changes, applications, standards and guidelines

Technical information on the connection of a 37° Flare Fitting to a threaded coupling to DIN 3853 with 24° cone (Port Form W to DIN 3861) .

Operation

In order to connect a 37° flared pipe to a 24° inside cone, a flare adaptor, BV-202 should be used. This adaptor has the respective angles of the fitting and of the pipe and is fitted with an O-Ring on both sides so that a high quality elastomer seal to both sides is made. The Flare Nut has a metric thread, allowing connection to the standard compression fitting. The pipe has to be flared in accordance with ISO 8434-2, Table 5, ensuring that the O-Ring on the Flare Adaptor is fully covered by the flare. The flare dimensions are given in the table below.

Assembly

Press the Flare Adaptor BV-202 by hand into the 24° Cone as shown in the diagram above. Slide the Flare Sleeve, BV-203 and the Flare nut, BV-201 onto the flared pipe and hand tighten onto the Stud Coupling. Then tighten the Nut with a spanner approximately 1/4-1/2 turn. The coupling should be held with a second spanner.
