Hexmesh

Hexagonal mesh or Hexmesh as it often referred to is a honeycomb pattern of steel bars used to retain refractories in
anti-abrasive and anti-corrosive thin wall linings used in the oil, petrochemical, metallurgical, chemical, and cement industries.

VICO-Still® hexmesh

Hexagonal mesh, Hexmesh or Hexmetal as sometimes referred to is a honeycomb pattern of steel bars used to retain refractories in anti-abrasive and anti-corrosive thin wall linings used in the oil, petrochemical, metallurgical, chemical, and cement industries.

The VICO-Still® range of hexagonal mesh comprises many different styles with or without protruding lances to meet the specifications set by process engineering companies and refractory suppliers.

It is manufactured in a honeycomb configuration by using shaped metal plates joined together by a special locking system (often referred to as “tight clinch”) to guarantee high stiffness even after rolling.

VICO-Still® hexagonal mesh can be supplied in flat panels manufactured from 19 or 25mm thick plates and supplied in panels 2000x1000mm or rolled and tailored for welding to the walls of cyclones, reactors, furnaces and vessels.

VICO-Stillflex

VICO-Stillflex is a complementary product made from shaped metal flat wires connected with rods to guarantee flexibility in one direction and eliminating the need for rolling prior to installation. This characteristic means that VICO-Stillflex available in 1020mm wide rolls is most suitable for small diameter cylinders, such as cyclone diplegs, ducts, fan casings and small cylinders. Most material requirements are for AISI 304H, 410s & 310s, but others are available as are different widths against specific request.

Advantages

Petrochemical and Chemical Industry

  • Can be supplied in rolled and tailored form to suit vessel configuration and wall contours.
  • Stock availability of VICO-Still flat rectangular panels 2000×1000 mm in 19 or 25mm thick.
  • The easy rolling capability of VICO-Stillflex simplifies armouring pipes of small diameter.
  • VICO-Still accepted as a preferred supply source by leading process engineering companies.
  • VICO-Still hexagonal cells supplied with or without lances and central or staggered lances.
