          我們同時依據海外他國標準,制造生產多種標準封頭如下:

          We manufactures Heads according to PED 97/23 EC for pressure vessels. The stainless steel material is certificated according to Pressure Equipment Directive (97/23/EC).
    The dished and flanged heads are manufactured with PED/ TüV standard plates aiming the production of pressure machines.

    We proceed according to the following manufacturing laws: CODAP, ASME, ADM.

          We manufactures stainless steel tank heads, in order to avoid any pollution from other materials. This point represents another guarantee of quality for all our clients.

    - NF E 81-100 December 1997 – Dished heads, designation, tolerances.

    - German tolerances DIN28011 et DIN28013

     

    We manufactures the following type of heads:

    · PRC Small knuckle radius head N FE 81-101 or Shallow Head

    · GRC Large knuckle radius head N FE 81-102 or Torispherical head DIN28011

    · Elliptical head N FE 81-103 or Semi Ellipsoidal Head DIN28013

    · MRC Medium knuckle radius head N FE 81-104

    Edge machining and bevelling are made according to the N FE81-110.
