products & developments Lightweight and durable alternative

For pipe clamps in the Standard Series as per DIN 3015 (Part 1), which are designed for easy and secure fixing of metric or inch pipelines with outer diameters from 6 to 102mm, Stauff offers an aluminium alternative for all dimensions of mounting hardware such as cover plates and weld plates. Even in the Heavy Series as per DIN 3015 (Part 2), certain components and sizes are available in aluminium. The dimensions and material thicknesses of the aluminium components correspond to the standard surface-treated designs generally made of steel or stainless steel, and therefore facilitate the use of bolts of conventional types and lengths, using the usual recommended tightening torques. Due to the low tendency to corrosion when in contact with aluminium, the use of bolts with the standard Stauff zinc/ nickel coating (material code W3) is possible. The retention forces of the tested pipe clamps in direction of the cover plates, which were tested and documented under controlled conditions at the Stauff in-house laboratories, met the requirements.

higher malleability and lower residual stress of aluminium components.

Stauff has introduced aluminium mounting hardware for pipe clamps for the ship construction industry. There are numerous benefits of using aluminium in machine and plant construction. Although aluminium is considered to be a light metal with a density of 2.6 to 2.8g per cm 3 , which offers a potential weight saving of up to 66 per cent compared to steel and stainless steel, it still has exceptional strength considering these properties. However, the design and concept of steel constructions can often not be transferred one-to-one, due to the Heavy Series pipe clamp with cover plate made of aluminium

An additional benefit is the aluminium’s inherent resistance to corrosion. When exposed to oxygen, the light metal forms an oxide coating, which is immediately regenerated upon permeation. Standard processing methods, such as MIG, TIG and CMT welding, can easily be used on aluminium, particularly on substrates that are also made of aluminium. In some instances, they can be carried out more easily, more quickly and using simpler equipment. The

magnetic neutrality can also be a beneficial side effect of using aluminium. There is an increasing trend towards using special seawater- resistant, high-strength aluminium alloys for com- ponents and assemblies on sailboats and yachts. These materials, which contain small portions of magnesium, manganese and silicon in addition to aluminium as the main component, are popular due to their quality and attractive appearance. In contrast to wood, they do not require continuous treatment or sealing.

Flexible rubber tubing Artel Rubber Company manufactures and fabricates silicone and rubber tubing and hose. The company’s flexible rubber tubing withstands repeated bending, stretching and pulsating forces, and is stocked in various sizes for fast delivery.

is seamless, uniform and smooth for maximum flow. All ingredients are non- toxic and conform to FDA standards. A variety of fittings and clamps are also available. Synthetic latex and reinforced wire tubing is offered as a custom item. It is made without the allergen-causing protein found in natural latex. ISO 9001:2008 accreditation ensures quality for the rail, automotive, food, pharmaceutical and defence industries.

Known for its flexibility, latex is among the most elastic rubber materials in use. Resiliency is another quality of latex tubing, allowing it to maintain memory after repeated elongation, distortion and pulsation. Artel’s latex tubing also withstands repeated sterilisation with steam, ethylene oxide or gamma radiation. There are no added plasticisers, coagulants or fillers to migrate and contaminate the stream or cause tube hardening, and the tubing remains flexible even at cold temperatures.

The natural latex rubber tubing, for applications requiring repeated flexing and stretching, is used by the health care industry, car and bus/truck companies, large food manufacturers, train companies, MOD, heating (boilers), engine companies, high- end car companies, large equipment companies, marine, construction and wind turbines.
