BSTFLEX multi-layer stainless steel mesh flange guards combine an external metal band with a layered stainless steel mesh insert around a flanged connection. The mesh-lined construction is intended to interrupt a concentrated release from the joint, making the internal mesh arrangement an essential part of the guard specification rather than an optional description of the outer cover.
These stainless steel flange spray shields are specified against the connection dimensions, process medium and required protective function. The band, mesh and closure form a complete assembly that must be selected together.
Explore our Flange & Valve Protection Covers range for related flange guards, valve spray shields and removable insulation covers.
The outer band surrounds the flange perimeter, while the multi-layer mesh is positioned on the inside of the guard around the joint. Its purpose is to interrupt and distribute a concentrated leak jet rather than leave the release acting directly against a plain metal surface.
The protective result depends on the complete construction, fit and service conditions. Mesh grade, arrangement, coverage and retention should therefore be included in the agreed product specification. A material grade or an external photograph alone does not establish spray-control performance.
This product is an external spray guard, not a pressure-retaining enclosure or a repair for a failed flange connection. It does not replace the sealing function of the gasket, flange faces and bolting.
The formed metal band fits around the outside of the flange assembly. Its diameter and width are matched to the connection so that the guard can be positioned without interference from bolts, nearby equipment or existing insulation.
The internal mesh distinguishes this construction from a guard specified only by its outer band. The mesh must remain correctly positioned in the assembled cover. Its dimensions, arrangement and attachment details are defined in the approved configuration.
A latch closure allows the assembly to be opened for fitting and removed during planned maintenance. Closure design and component materials are confirmed together with the band and mesh requirements.

| Intended Function | External flange spray protection; not leak repair or pressure-tight containment |
| Service Conditions | Process medium, normal and maximum temperature, and pressure to be reviewed for the proposed assembly |
| Testing and Documentation | Required acceptance criteria and documentation must be identified before order confirmation |
Specify the required stainless steel grade for all relevant components, including the mesh and latch. Do not assume that identifying the outer band material automatically defines the material of the complete guard.
Steam, fuel oil, lubricating oil and diesel systems are examples of duties for which mesh-lined flange spray shields may be considered. Each application requires review of the medium, operating conditions, connection geometry and protection objective before a configuration is selected.
For projects with special environmental, marine or inspection requirements, include those requirements in the initial inquiry. Any required qualification or test documentation must apply to the supplied assembly and its stated conditions of use.
Provide the flange standard, nominal size and pressure designation together with a drawing or measured dimensions. The outside diameter, assembled width, bolt projections and surrounding space are important inputs for sizing the guard.
Photographs should show the front and side of the connection, including nearby supports, insulation and operating mechanisms. For multiple installations, identify each connection on a flange schedule so that different sizes and access restrictions can be reviewed separately.
For comparison with the outer-band product configuration, see our stainless steel band-type flange guards. For the product on this page, the internal multi-layer mesh must also be included in the specification.
Installation must follow the approved assembly instructions and the site's safe-work procedures. Have authorized personnel make the connection safe before fitting or removing the guard. Do not approach an active leak to install or adjust a cover.
Check the guard size and position the mesh according to the approved drawing. Secure the closure without forcing the band or displacing the mesh. Keep any specified inspection, drainage or venting provisions unobstructed.
During scheduled inspection, examine the band, mesh and latch for damage, corrosion, contamination or displacement. Continued use must be assessed against the condition of the complete assembly.
The construction described here combines an outer metal band with an internal multi-layer stainless steel mesh insert. The mesh and the surrounding band are specified as parts of one guard assembly.
No. Performance must be assessed for the actual materials, mesh arrangement, coverage, fit and service conditions. A mesh insert alone is not evidence of a particular pressure rating or mist-control result.
No. The flange designation identifies the piping connection. Any required spray-shield performance or testing must be specified separately for the complete guard assembly.
They are not offered as leak-repair devices. A leaking connection requires the appropriate isolation, inspection and repair procedures. Spray protection does not restore the integrity of the flange seal.
Send BSTFLEX your flange standard, dimensions, material requirements and quantity. Include the process medium, operating temperature and pressure with clearly stated units, together with the required protective function.
Attach connection drawings or photographs and identify any specified mesh construction, testing, inspection or material documentation. For a multi-size project, include a flange schedule and the requested delivery date.
