Product Description

Self-aligning hydraulic butt fusion machine, suitable for welding under-pressure pipes for water, gas and other fluids. Built according to the international stands (UNI 10565, ISO12176-1). Includes:

-A machine body: built with a supporting frame, four clamps and four clamps and two hydraulic cylinders with fast non-drip coupling connections.

-A heating plate with a built -in independent thermometr, to check the working temprerature, and an high-precision electronic thermoregulator with digital display and reguating butons. Contingent probe’s failure led indicators to check if the machineis working nomally, contingent probe’s failures and/or temperate anomailies.

-Milling cutter to face the heads of the pipes and/or fitings. It includers a safety micro-switch and a thermal circuit breaker.

-An elctro-hydraulic gearcase potected from crashes and atmospheric corrosion by a plstic box. It includes a control lever, to open and close the clamps, maximum pressure and discharge vales, hydraulic connection hoses with non-drip fast coupling and timer. The machine is preset for the connection of electronic controller which come with a high-temperature -proof bag, which also protect the heating element from being scratched.

The mode is able to weld fittings like elbows ,tees, Y-branches and flanges necks.

WELDING PARAMETERS

9.1. PIPE / FITTING FEATURES

The classification of the pipe / fitting in SDR, Series (S), Nominal Pressure PN, and the welding parameters to be applied, they all depend on the size of the pipe / fitting to be used:

D: Outside diameter of the pipe / fitting;

s: Thickness of the pipe / fitting wall (use a calliper for this measurement).

The following formulas and ratios apply:

Standard Dimension Ratio

Series

SDR	41	33	27,6	26	22	21	17,6	17	13,6	11	9	7,4	6
S	20	16	13.3	12,5	10,5	10	8,3	8	6,3	5	4	3,2	2,5

PN (PE 80)	3,2	4	///	5	6	///	///	8	10	12,5	16	20	25

PN (PE 100)	4	5	6	///	///	8	///	10	12,5	16	20	25	32

PN (PP)	2,5	3,2	///	4	///	///	6	///	///	10	12,5	16	20

(Nominal Pressure at 20° C)

Herewith is a list of formulas used for calculating the welding parameters, and the tables of parameters (in compliance with various regulations for the most common diameters and thickness of pipes / fittings).

NOTE 1: The value of the approaching pressure P₁, which is equivalent to that of the welding pressure P₅, is to be set at the gearcase and is obtained by adding the corresponding calculated value (or obtained from one of the herewith given tables) to the value of the dragging pressure (P_t) measured by the oforator at the machine.

NOTE 2: Before consulting the tables herewith, the oforator must make sure that the real size, as measured at the pipe / fitting, actually corresponds to the nominal ones of that particular pipe / fitting. If not, and only in case the real dimensions of the pipe / fitting respect the regulated tolerances, the oforator must calculate the welding parameters by using one of the formulas herewith given. Use a callifor for this measurement.

NOTE 3: The values mentioned apply to a welding ambient at 20°C with adequate protection from adverse weather conditions.

NOTE 4: All calculations must be done in mm (pipe / fitting D diameter and s thickness).

A calculation referred to a commercial pipe (with a standard dimension) can be found next to the general formula, as an example.

Application

The ZYRD is an on-site welding machine equipped with a heating element for butt-welding of pipes and/or fittings made of Polyethylene (PE), Polypropylene (PP) and other thermoplastic materials intended for carrying combustible gas, water and other fluids under pressure.

The ZYRD can weld PE100 with the “Dual Pressure” method.

The use of this welding machine is only allowed to trained staff having the qualifications required by the regulations in force.
