COMMERCIAL MARINE

The greatest natural threat to the structural integrity of a marine vessel’s hull is corrosion, but a well-selected anode is a powerful ally against this threat. To help combat the corrosive effects on the vessel’s hull, zinc and aluminum marine anodes are commonly used. Zinc anodes have a long history of use in the industry, but are most suitable for saltwater, while aluminum is suitable for salt, fresh, and brackish water. The type of vessel and which component needs protection (such as hull, rudder and heat exchangers) will also play a role in the selection of the type of anode, as well as its format.

OIL & GAS

Anodes are essential to the oil and gas industry for controlling the corrosion faced by submerged structures. High-grade zinc anodes are most effective in saltwater, a critical need for the petrochemical industry, while high-quality aluminum anodes are preferred for fresh and brackish waters, but are also effective in saltwater. Many production vessels such as heater treaters, storage tanks, pressure vessels, heat exchangers, skimmers, and oil-separation vessels, rely on treater anodes in zinc or aluminum, which are cylindrical, easy to replace, and suitable for challenging conditions (e.g. produced brines with elevated temperatures). The wide-ranging needs of this industry require experienced and precise selection of these parts.

PLUMBING

Given the applications of solder in the plumbing industry and its potential contact with drinking water, regulations call for lead-free solders. Some typical types of solder used in plumbing are tin, silver, and various alloys, all of which are specially selected to be resistant to oxidation and have the necessary low melting point. However, lead solder is still widely used, and coveted for its low melting point, in other appropriate applications. In plumbing situations where there is no contact with drinking water, such as in the transportation of wastewater, extruded lead pipes, tubes, and plumbing joints are considered a useful and safe material.

CONSTRUCTION

On the market today, lead flashing is considered a durable weatherproofing material for use in construction and roofing projects. Its inherently malleable and flexible nature makes it easy to use and suitable for a diverse number of roof types. As lead is a non-ferrous and non-reactive metal, it is naturally resistant to corrosion and will not rust. From an aesthetic point of view, its muted, silver -grey finish complements a variety of building materials such as glass, concrete, and brick. These same weather resistant benefits of lead, along with its density, also make it a compact and resilient option for counterweights on heavy construction equipment. Lead because of its density, is also used as the filler in pile driver hammers.
