Can the Heavy-duty screw clamp with movable bridge for heavy loads SUPRA HEAVY DUTY W4 be used in marine and food industry environments without corrosion issues?

Yes. The Heavy-duty screw clamp with movable bridge for heavy loads SUPRA HEAVY DUTY W4 is suitable for marine and food industry environments: it is the W4 version made entirely of stainless steel and specifically intended for demanding applications where high corrosion resistance is essential â including marine applications and the food industry. The band and bridge are AISI 304 stainless steel, and the screw and rollers are AISI 302 stainless steel, offering good general corrosion resistance. Note the clamp is RoHS-compliant and designed for heavy-duty use with uniform sealing and reliable pressure. Consider application specifics: AISI 304/302 perform well in many food and marine settings but may be susceptible to pitting in highly chlorinated or very aggressive saltwater environments; for extreme seawater or prolonged direct salt exposure, higher-grade stainless (e.g., 316) may be preferable. Also respect the recommended tightening torque (avoid pneumatic tools) to prevent housing deformation.

Is the Heavy-duty screw clamp with movable bridge for heavy loads SUPRA HEAVY DUTY W4 suitable for saltwater exposure and seafood processing?

Heavy-duty screw clamp with movable bridge for heavy loads SUPRA HEAVY DUTY W4 is suitable for saltwater exposure and seafood processing. The W4 version is made entirely of stainless steel and is intended for demanding applications where high corrosion resistance is essential - specifically for marine applications and the food industry. However, the band and bridge are AISI 304 while the screw and rollers are AISI 302; both are stainless but 304/302 offer moderate corrosion resistance in chloride environments. For prolonged, continuous exposure to aggressive saltwater or highly corrosive seafood processing conditions, consider higher-grade stainless (e.g., AISI 316) or frequent inspection and maintenance to prevent corrosion. Maximum working pressure up to 45 bar depends on hose type and clamp diameter.

Does the Heavy-duty screw clamp with movable bridge for heavy loads SUPRA HEAVY DUTY W4 resist corrosion in chemical or industrial cleaning environments?

Yes. The Heavy-duty screw clamp with movable bridge for heavy loads SUPRA HEAVY DUTY W4 is designed for demanding applications requiring high corrosion resistance. Its W4 construction uses stainless steel throughout: the band and bridge are AISI 304, and the screw and rollers are AISI 302, making it suitable for corrosive environments such as marine settings and the food industry. It is manufactured to RoHS standards and provides robust, uniform sealing and high working pressure (up to 45 bar, depending on hose and diameter). Note: while corrosion-resistant, AISI 302/304 stainless steels have limits in highly aggressive chemical environmentsâcompatibility with specific chemicals and concentrations should be verified before use.

Additional information

Material	SS – stainless steel

High-quality, strong clamp with a hinged closure for heavy loads with turned-up edges of the band, recommended for securing thick-walled, reinforced industrial hoses and pipes. The unique design ensures uniform pressure around the entire circumference, providing optimal sealing. The movable bridge allows for multiple installations without the need to remove the hose. Manufactured in accordance with the RoHS Directive 2002/95/EC. Three-point welds on the band, a high-strength screw with a spacer along with securing half-rollers guarantee maximum and reliable pressure. The clamp features markings on the band for minimum and maximum diameter as well as the material from which it is made. The W4 version of the clamp is made entirely of stainless steel and is intended for demanding applications where high corrosion resistance is essential – for marine applications and in the food industry. The hexagonal head of the screw allows the use of commonly used tools such as flat wrenches, socket wrenches, and adjustable wrenches. Important! Exceeding the tightening torque value will cause the screw housing to bend; the use of pneumatic tools for installation is not recommended. The band and bridge are made of AISI 304 steel, while the screw and rollers are made of AISI 302 steel. Maximum working pressure up to 45 bar depends on the type of hose and clamp diameter.
