Scarfing longitudinally welded tubes During the last 15 years, Saar-Hartmetall und Werkzeuge GmbH has reinforced its team, dedicated to techniques of scarfing longitudinally welded tubes.

stencilling and colour banding. Being able to produce a stamp and stencil that can print the correct information as well as being visible at the end of the mill process is a difficult task. Brandt works closely with customers to understand the environment and correctly choose the appropriate inks and paints. Stencilling is accomplished with either a travelling stencil carriage attached to an overhead truss, or by moving the pipe and keeping the stencilling equipment stationary. Stencilling will brand each pipe with customer- specified information such as length, weight and any logos that may be required. Further solutions can include application of barcodes for quick and accurate pipe tracking. A turning roll is used to turn the pipe during the application of a colour band. Paint is supplied to automatic spray guns via large pressure pots with agitators to ensure the equipment is usable on demand. Stamping is another option that customers can choose to add to the WMMS. Brandt Engineered Products Ltd – Canada www.brandt.ca Saar-Hartmetall’s partnership with a coating centre allows the company to improve all kinds of specific scarfing problems. New products include short inside scarfing tow bars, and a new hydraulic power pack with pre-selected pressures and return button to accelerate the ‘out of cut’ movement. The company has also produced a new impeder filtration and pressure station with easy handling. Saar-Hartmetall und Werkzeuge GmbH – Germany tube@saar-hartmetall.com www.saar-hartmetall.de

The company’s staff have completely revised its range of products, and have made important innovations in the design of the tooling and in the quality of the carbide inserts concerning geometry and carbide grades. The company is always involved in specific projects and customised equipment. Its hydraulic inside scarfers start from 19mm inside diameter, and its mechanical tooling from 14mm ID.

Inspection, length measurement and weighing

to each station. Each unit has the option for inspection, length measurement, weighing, pin stamping, stencilling and colour banding pipe. Each of the steps is recorded in a custom data logger, sent to the customer’s database and available on screen for instant observation. Lengths and weights need to be measured accurately and repeatedly. Brandt has been able to employ photo sensors and high-resolution encoders that can ensure lengths are measured and recorded within the guidelines of associations such as API. The weigh station is able to maintain defined tolerances over repeated use.

Brandt Engineered Products has provided finishing floor solutions for the tube and pipe industry for over 30 years. During that time it has engineered ways to ensure its equipment produces high quality pipe, while being robust enough to withstand the difficult environment that it operates in. The company’s Weigh Measure Mark Stencil (WMMS) provides a quick and accurate way to help ensure that customers are receiving material that adheres to their strict standards. The WMMS uses a PLC to automatically move pipe and capture measurements. It uses a walking beam to transfer pipe

Shock absorbers and load cells are designed to ensure that the weights are measured precisely over a wide range of lengths and diameters, often within ±0.5 per cent. Labelling the pipe with a visual record of specifi- cations and information observed during testing is accomplished by stamping,
