Saw blade for efficient orbital cutting Kinkelder has developed the smooth cutting TubeMaster ® saw blade for orbital cut off applications. Its special tooth-geometry cuts a large range of thin to thick wall tubes. cutting thin wall (<4mm) tubing, thereby achieving an excellent blade life.”

Tubes for oil and gas as well as structural pipes and hollow sections form the primary market for TubeMaster saw blades. Even high hardness materials such as X80 can be cut efficiently thanks to the type of carbide used. The PVD coating protects the tips against the high temperatures developed during the cutting process. The USA, south European and South American countries were the first to discover the advantages of the new blade, and the popularity of the flying

The saw blade concept allows using one set of blades with medium tooth pitch to cut tubes with wall thickness from 3 to 9mm, and on some machines up to 12mm. For wall thickness 9 to 30mm, a coarse pitch is defined. TubeMaster saw blades are available in diameters from 300 to 420mm for all types of orbital cutting machines, such as MTM, Otomills, Elmaksan, Kusakabe, Linsinger and SMS.

“Key features of this TubeMaster saw blade are a special carbide grade and a high tech PVD coating,” said Kinkelder application engineer Leo Molenaar. “This, combined with a special cutting geometry, does not require much force for chip removal, assuring a milled like finish of the cut surface. This special geometry also reduces vibration when

cut-off concept is growing in other countries as well.

Ductile iron pipe earns SMaRT certification

95 per cent recycled content. It is designed to last up to a century or more. “DIPRA member companies are dedicated to protecting the health and wellbeing of its employees, its neighbours and the customers of the utilities that use ductile iron pipe,” said DIPRA president Gregg Horn. “This commitment to environmentally sound practices only adds to the long- recognised value of our product. We are proud to be a leader in the field of sustainable water and wastewater infrastructure.”

Sustainability categorised ductile iron pipe with its esteemed Gold rating thanks to the pipe’s rankings in the following categories: safe for public health and environment; renewable energy and energy reduction; bio- based or recycled materials; facility or company requirements; reclamation, sustainable reuse and end of life management; and innovation in manufacturing.

The Ductile Iron Pipe Research Association (DIPRA) has announced that ductile iron pipe, a durable and environmentally friendly choice for water utilities, has earned the coveted SMaRT © Sustainable Product Certification, an independent rating system for the sustainability of a product throughout its life cycle. Ductile iron pipe is only the second product in the buried infrastructure industry to earn this certification. The Institute for Market Transformation to
