Breather valve are designed to protect low pressure storage tanks from excessive pressure(or vacuum) created by thermal expansion(and contraction) and product movement into(out of) the tank and at the same time minimizing costly product evaporation/loss
Vaccum valve - Prevent passage of flame into cargo tanks and to relieve pressure and vacuum during cargo loading and unloading or ballasting or thermal variations and gas freeing purposes on cargo tanks
Benefits:
- Includes gas freeing vent cover
- Easy maintenance
- Saving of the gas freeing vent and pipe post cost.
Our Steel Walkway System (Catwalk Systems) are a walker attached to the roof system by means of SC-8 oppressors that do not pierce the SSR sheet. It oers a non-slip and safe surface to travel on the roofs and perform maintenance activities on A / C equipment, extractors, etc.

Cal galvanized material. 14, 16, or 18.
Easy and fast installation.
Without SSR roof perforations.
Maintenance free.
Optional safety rail.
Special oppressors for dierent types of panels.
CATWALK SYSTEM
Prefabricated, yet custom metal catwalk designs.
Custom decking options for foot-traffic, pallet jacks, building codes, and more.

5. PROCESSING:
Types 304 and 304L cannot be hardened by thermal treatment. Annealing: Heat to 1850o F to 2050 o F and cool at sufficiently high rates through 1500oF to 800oF to avoid precipitation of chromium carbides. Stress Relief Annealing: Cold worked parts should be stress relieved at 750oF for ½ to 2 hours.
