Welding defects are generated in a welding job due to the faulty or poor technique used by the inexperienced or unskilled welder or due to fundamental difficulties in the welding operation. An ideal weld or good weld should be such that adequate fusion exists between the filler metal and edge preparation together with good penetration. FUSION EQUIPMENT For Thermoplastic Pipe Installations. Our welding equipment is designed and manufactured according to the American international standard ASTM F – We have a specialized team with knowledge in fusion procedures and maintenance experience.

Acrobat A versatile machine designed for butt fusion of 63mm to mm (2" IPS to 6" DIPS) pipe and fittings. Learn More; Acrobat™ A compact design for tight indoor work spaces, the fuses pipe and fittings from 63mm - mm (2"- 10”). Book Pipe Fusion Consulting Ted Hutton - Plastic welding and thermoplastic welding consultant Ted Hutton is a thermoplastics expert specialist with over 50 years of experience in the industry.

You will be trained to perform butt-welding using high force and low force parameters within factory environment. Understanding calculations, you will set up welding equipment and work area. Performing multiple welds using different pipe sizes, you will monitor . PE pipe used for water systems is typically designed for mechanical fittings, which requires that it be I.D. (inside diameter) controlled. This pipe would not work well for fusion (especially socket fusion), since the fusion fittings depend upon a consistent O.D. (outside diameter). HDPE must be specifically designed for heat fusion and for.

Study of the butt fusion welding of thermoplastic pipes by Stephen Shillitoe Download PDF EPUB FB2

A study of the butt fusion welding of thermoplastic pipes. Author: Shillitoe, Stephen. Butt fusion welding is the name given to hot plate welding of thermoplastic pipes. It is one of two main techniques for the fusion joining of polyethylene gas and water pipes. There are five elements in the butt fusion joining process: Bead-up - The trimmed and aligned pipes are pressed against the heater plate using the 'initial' bead-up pressure.

The pressure is maintained until the pipe begins to. Topics: 13K - Pumps, filters, pipes, tubing, valves, pressure vessels, 13E - Couplings, fittings, fasteners, joints, 11I - Plastics, A study of the butt fusion welding of thermoplastic pipes [ Welding of plastic pipes!]Author: S Shillitoe.

(First received 31 August ; accepted in revised form 22 January ) Abstract The study of the butt fusion welding of thermoplastic pipes. book up stage of the butt fusion welding of plastic pipes is modelled by treating the melt layer as a squeeze film contained between two parallel annular rings to Cited by: 8.

Butt fusion welding is the most reliable and unobtrusive method of joining PE pipes (and spigot fittings) of virtually any size-except perhaps the smallest where other methods are usually preferred. It is the dominant method of jointing both medium and large pipe. Butt Fusion Welding of HDPE Pipes Work Procedure A pipeline is as good as its weakest point.

Accordingly it is not only important that quality pipes and components are used in a piping system, but also the methodology used to join the pipes and other components. Butt Fusion is the most important and widely used method of connectionFile Size: KB. the fusion type and for the sizes of pipe and fittings to be joined.

Butt Fusion Extrusion welding or hot air welding is not recommended for pressure applications. Butt Fusion Socket Fusion 2. INCLEMENT WEATHER PE has reduced impact resistance in sub-freezing conditions.

Additional care should be exercised while. Butt fusion welding is the name given to hot plate welding of thermoplastic pipes.

It is one of two main techniques for the fusion joining of polyethylene gas and water pipe. The Process. The heating phase, sometimes referred to as 'bead up', is where the pipe ends are. hot air (hot gas) welding, or extrusion welding techniques and joining by pipe threading are not recommended for pressure service.

Canadian regulations When used to join Uponor Infra polyethylene gas pipe and fittings, Uponor Infra fusion joining procedures are qualified in accordance with Canadian Standards Association Regulations. Butt Welding Butt Welding is the name given to hot plate welding of thermoplastic pipes.

This involves the simultaneous heating of both ends of the pipeline that is to be joined until a molten state is achieved on each contact surface in the bead up process. Butt Fusion The most widely used method for joining individual lengths of PE pipe and pipe to PE fittings is by heat fusion of the pipe butt ends as illustrated in Figure 1.

This technique produces a permanent, economical and flow-efficient connection. Quality butt fusion joints are produced by using trained operators and quality butt fusion.

@article{osti_, title = {Inspection of Fusion Joints in Plastic Pipe}, author = {Reichert, Connie}, abstractNote = {The standard method of joining plastic pipe in the field is the butt fusion process.

As in any pipeline application, joint quality greatly affects overall operational safety of the system. Currently no simple, reliable, cost-effective method exists for assessing the quality.

High productivity butt fusion jointing of PE pipes. Author(s): Cartwright, Troughton, Hinchcliff, Bowman, Jenkins Edinburgh. For the butt fusion joining of PE80 polyethylene pipes on site, long heat soak and cooling times predominate in the United Kingdom and other countries.

Introduction: A Welder's Guide to HDPE Pipe Fusion. A guide primarily for men and women working with HDPE pipe, whether in landfill gas systems, domestic water supply or otherwise.

Ask Question. Description. FUSION EQUIPMENT For Thermoplastic Pipe Installations. Hayes Industrial Solutions Inc. has specialized in providing world-class butt fusion machines that weld thermoplastic pipes such as polyethylene HDPE and polypropylene PPR, which in turn give consumers high quality, exceptional durability and commercial-grade butt fusion machines that deliver a superior weld with ease of use.

The manual butt-welding machine model S Hand can be used for butt fusion of thermoplastic sheets (e.g.

PVC-U, PE-HD, PP, PVDF). The. This specification covers polyethylene (PE) butt fusion fittings for use with polyethylene pipe (IPS, DIPS, and ISO) and tubing (CTS). Included are requirements for materials, workmanship, dimensions, marking, sustained pressure, and burst pressure.

DELTA TRAILER is a self-aligning fusion machine, suitable for welding thermoplastic pipes for the transport of water, gas and other fluids under pressure, up to Ø mm (36" IPS/DIPS). Machine can fuse pipes according to the ISO High Pressure standard.

Electrofusion welding and butt fusion welding are common methods for joining polyethylene pipes used for water and gas distribution. Because of the wide use of these two methods in infrastructure engineering, welded pipe joints and pipe materials should be.

Generic Butt Fusion Joining Procedure for Field Joining of Polyethylene Pipe. TR Decker Court, SuiteIrving, TX Phone: Fax:. A third method of thermoplastic welding is called sidewall fusion, or saddle fusion.

Sidewall fusion is, like butt fusion and socket fusion, another process based on hot plate welding. Sidewall fusion differs from either socket, or butt fusion methods by performing fusion into the side of the pipe wall in a transverse orientation to the main.

Experimental and Optimization studies of Electro-fusion and Butt-fusion welding of HDPE pipe material have been conducted and the welded specimen are Tensile tested using UTM. The optimised results obtained from Grey based Taguchi and ANOVA optimization techniques are depicted through Table 8, Table 9.

Table 8.piping systems can use heating element socket welding, heating element butt welding or the no-contact infrared (IR-Plus®) fusion technology developed by GF. The internal pressure resistance is ensured through long-term testing in accordance with EN ISO and certified with the value of MRS 10 (minimum required strength).
