UNION FLANGES FOR "SPIRO®" CIRCULAR DUCT

We manufacture a wide range of union flanges. Available in Galvanized Steel DX51 D + Z Z275 MA, from Ø 100 mm to Ø 3,000 mm, in 4 sizes. These are determined according to the rigidity required by each diameter. Standard version with screw closure (optionally with latch fitting closure). All the edges of the frames are finished (no sharp edges). The risk of getting any cut injury handling them is completely eliminated.

Since its design is formed by multiple folds, it has a great rigidity while adapting perfectly to the edge of the duct (no internal ripples = better airtightness). The “V” closure has a built-in polyethylene seal M-1 (closed cell).

It is also produced on demand with the specifications for High Temperature with ceramic gasket M-0 for 1,000 ° C with only an increase of the 15% over the price of the standard flanges. The entire range of diameters is also manufactured in STAINLESS STEEL AISI 304/316.

They meet the level C airtightness, test carried out by independent laboratories BSRIA, (according to the requirements of UK HVCA Specification DW 143 – DW 144).

Its components are also sold separately: € of a “V” closure =  € of 2 Frame Rings.

Innovative PATENTED design. Product totally designed and manufactured in Spain.

UNION FLANGES FOR OVAL DUCTS

PRESENTED AS A NEW PRODUCT AT:

EFFICIENCY

We have recently developed and patented an innovative joint system for oval ducts.

The oval ductwork combines the advantages of the best performance of the circular duct with the lowest height of the rectangular duct. Therefore, it is recommended for installations that, without having much space in height, require maximum efficiency..

INNOVATION

It is composed, just like the “SPIRO®” duct flanges, of 2 flange rings and 1 closure “V” ring that has the built-in sealing gasket. The union of the sections to be joined is done by tightening 2 nuts only. These 2 closures of the union are located diagonally opposite. This system evenly distributes the pressure of the gasket over the entire perimeter of the flange rings.

EXCLUSIVENESS

– The whole assembly, as it is, deserves its exclusivity to be a world novelty, since it allows the assembly of the duct being «stuck to the ceiling», having one closure accessible from below and the other is to be screwed laterally using a pipe wrench with extension.

This product is totally designed and manufactured in Spain.

DIVIDING RUBBER JOINT FOR DOUBLE DUCT SPIRO®

PRESENTED AS A NEW PRODUCT AT:

INNOVATION

  • Applicable in isolated double ducts, composed of straight sections and concentric accessories of equal lengths, with a difference between inner diameter and outer diameter of 50 m / m.
  • It’s made of M-1 rubber material.
  • Innovative PATENTED system that allows to completely eliminate the thermal bridge between inner duct and outer duct

EFFICIENCY

The complete joint, assembled as it is, has double sealing gasket: the first is formed by facing the 2 flange rings with their corresponding rubber gaskets and the second is the one that closes the assembly using the “V” closure with its own polyethylene gasket that is incorporated inside. The result obtained in this type of joint is of a maximum sealing level (CLASS-D level).

QUALITY

Stability tests have been carried out between the fixation of the two ducts placing vertically a section of 3 meters and suspending the assembly only from the outer tube. Several abrupt movements have been made to certify that the dividing joint holds the inner tube tightly in position.

RUBBER JOINT FOR THE UNION OF STAMPED ACCESSORIES

In addition to the RAMI-SYSTEM® flanges and for the installations of small diameters «SPIRO®» ducts, we have the UNION RUBBER JOINT M-1 (with double lip).

We have 2 options: with or without adhesive.

Used to joining the stamped accessories to the «SPIRO®» duct.

It meets the Class C airtightness level.

 

WITH THIS TYPE OF JOINTS YOU BENEFIT FROM 3 ADVANTAGES:

  • Simplifies the accessories of your stock to one single type, without duplicating them (with joint and others without joint).
  • Therefore, your investment costs are reduced.
  • On site, you can transform an accessory without a joint into another with a joint quickly and efficiently.

Due to the proximity of walls or corners inaccessible by the opposite part of the duct, sealing is impossible. This method becomes your best solution.

We recommend its use up to 300 mm diameter..
