The company DWT is a family owned company, located in the industrial heart of Germany. The head-quarter is situated in Bottrop, where production and central stock is located. The company was founded 1987 as main supplier of the German mining companies. Nowadays we deliver products all over the world to different markets and for many different applications. Today we are focussing on the following business units:

• Sales & Service of industrial production equipment in the German market

• Production and sales of nitrogen generators for diffe-rent applications

• Production and sales of pipe beveling equipment under licence of BABCOCK worldwide

DWT Babcock

Ten years ago DWT has taken over the production of pipe beveling machines from the German steam boiler manufacturer „Deutsche Babcock“, who has developed the machines based on their on-site experience of their own engineers. The advan-tagesoflowweightandahighdegreeofflexibilityandcapacityprovedtheproductacceptability in the market. The ergonomic design for on-site use and low spare part need added to the advantage and created an unique product range.

Boiler Manufacturing Seminar

In this seminar effective solutions for productive manufacturing and repair of water wall boilers, water wall panels headers and heat exchangers have been presented. Theoretical lectures and practical demonstrations combined with factory visits made the seminar to a unique event for the boiler industry. In 2009 the seminar took place in Finland and already more than 80 boiler manufacturers were part of it. Also in the year 2011 a seminar took place in Essen, Germany in the factory of DWT GmbH. More than 100 steam boiler manufacturers from more than 30 countries and 5 continents have been invited by DWT.

Subsidiary

Since 2002 DWT has built up the export business of the pipe beveling and cutting market. Our application engineerswithsales&serviceofficesarelocatedinSingapore,Indonesia,MiddleEast,France,Malaysia,India, UAE, Spain and Russia to support our fast growing business all over the world.

Type CPC

CONCEPTchain type pipe cutting machine

The chain type pipe cutting machine is the perfect tool for cutting and beveling of pipes made of different material. Ductile Iron, Concrete, Cement, Clay, Plastics, PE, PVC and GFK can be cut and beveled. The chain driven pipe cutting machine is available with a pneumatic drive unit or with a hydraulic drive unit. For using the hydraulic pipe cutter we recommend our hydraulic unit DHP18E.

DESIGN AND DEVELOPMENT

The pipe cold cutting and beveling machine is designed in a compact way with aluminium al-loycomponents,whichgivehugebenefitstotheenduser:

• Compact design for limited access on pipe and pipeline work

• Reduced weight for more ergonomic work• Split frame technology for cold cut of endless

metal pipes• Designed for heavy wall pipes up to 80 mm

WT

Developed with German universities our tool tip solutions for pipe cutting and beveling provide an outperforming result in pipe cutting techno-logies:

• High metal removal rate for cold cut and bevel

• More durable cutter, reduction of consuma-bles

• Low cost of tool tips

The drives of the clamshell pipe cold cutter are a basic component of the pipe cutting machi-ne. All motors are west european standard. An adapter allows easy exchange of all motor types and sizes (pneumatic, hydraulic):

• Modular design• Easy exchange on-site• Reduced investment

DLW clamshell pipe cold cutter

The portable pipe cutting machine for steel pipe machining of pipes on-site is able to perform beve-ling and cutting of steel pipes as well as stainless steel and high alloyed steel pipes. The machines are reduced in weight and dimensions. The accessories allow multiple operations, like beveling and cuttinginoneoperation,insidebeveling,flangerepairofflangefacing.Theclamshellpipecutterisavailable from 3 - 57“. The pipe cutter can do all kind of pipe weld preparation by use of different tools.

INSERTS FOR MF PIPE BEVELING

The TiN duplex inserts are coated with titanium nitrid and are field-provensincemanyyears.Duetogeometryandcuttingedge of the insert they do a lotter better job than standard solid bits. Easy to be turned or changed on-site the extremely durable bits assure low costs, more precise operations by ge-nerating less heat and faster cut times increases productivity. The duplex TiN inserts are interchangeable in between seve-

ral machines and cut down the operating expenses.

Better Capacity and Quality Go Hand in Hand

Our partner is able to provide you tools to increase the capacity and quality of end product and thus raise your competitiveness. All lines are modular and designed based on customer’s production ca-pacity needs.

Toensureyourproductioncapacityfromrawmaterialtoaninspectedfinalproduct,youcanrelyonafully integrated systems. The integrated system from one supplier does not only ensure the capacity, but also gives the guaranteed quality.

High Output Panel Production in Mass Production

The panel welding line with two stationary panel welding ma-chines is designed for mass production of water tube panels. Theflexibleandmodulardesignofthelinemeansitcanbebuilt according to customer requirements. A line with a double stationary welding machine system produces up to over 3000 meters of weld in one shift.

The panel welding line with two welding machines and inte-gratedtubeandfin-barprefabricationsystemsisacompletepackage for high-productivity requirements. The line can be utilized with all necessary components for water tube wall pa-nel production from raw material handling to ready-welded panels. Standard panel widths are 2000, 2500 and 2700 mm. Other widths are also available on request. The length of the panel is set accor-ding to the customer needs.

Variable Layouts and Flexible Panel Production

PIPE AND PIPELINE WELDING EQUIPMENT

• Useful accessories for daily work on-site• Pipe welding clamps• Pipe Stands• Pipe Carts• Pipe Alingment Clamps

PIPE AND PIPELINE WELDING EQUIPMENT

• Single chain or double chain available• Clamping range: 8-60“• Max. wall-thickness: 15 mm• The chain is adjustable to all pipe diameters in the range

Pipeline chain clamps

Often pipe stands for pipe welding are still built in the workshop. Bet-ter, more safe and cheaper is the purchase of a professional pipe stand. The marking of pipes and the preparation of pipe ends for wel-ding becomes much easier. We offer a huge range of pipe stands for each pipe handling application for pipes with a weight up to 2 t.

Pipe stands

The Cricket pipe cart is for pipes up to 0,4 t and 6,1 m length. It is perfect for transport of material on-site and is delivered directly with lashing strap and fail-safe tyres.

Pipe carts

With pipe welding clamps easy installation and alignment of the pipes for welding is provided. Very well suited for use with different pipe materials like aluminum or stainless steel. Very interesting for use on- site due to lightweight design. For accurate alignment and clamping of pipeswithnolengthlimitationaswellaspipebends,flanges,t-fittings,reducersandotherfittingsforpipes.
