      我們同時根據海內他國尺度,制作臨盆多種尺度封頭以下:

      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.

 

Referenced norms:

- 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
