PulseGuard Incorporated & Limited Pulsation Dampers Supply Terms and Conditions

GENERAL TERMS and CONDITIONS OF SUPPLY - (by legal advisors to the company) The word "goods" shall mean equipment provided by the company. The "Company" shall mean the company that provides the price quotation.

1. Customer's special Terms and Conditions may be accepted but only if the customer has written by letter to the company and has obtained the company's agreement in writing to the customer terms and conditions prior to the quotation, which will other wise state a price and delivery based on these terms, as will our confirmation of your request for the supply of the goods or services.

2. Prices quoted may be based on estimated or advised annual usage. (a) Increases in the rate of call-off or total per annum (whichever shall be the lesser per annum rate) will be subject to a retrospective discount payable by us to you, for which you must apply when your quantity reaches another supply bracket. (b) Decreases in the rate of call-off or total per annum will be subject to an automatic percentage increase in prices invoiced or additional invoice at the end of the supply period where your quantity falls to another supply bracket.

3. (a) Price lists and quotations are only issued by the company in accordance with these Terms and Conditions and may be subject to alteration, in which case the company will notify regular customers and the price ruling at the date of despatch wil l be invoiced. (b) Prices are for the goods only and do not include for drawings, transparencies, operating instructions, parts lists, survey, inspection, testing, certification, precharging, special labeling, marking, or painting, packing, carriage, duty taxes , or extra documentation, all of which will be charged extra.

5. Every effort will be made to meet delivery dates which are quoted in good faith but the company will not accept responsibility for the consequence of any delay resulting from late supply of raw materials or subcomponents or industrial action.

Nota Bene

The designation of the unit and the parameters governing its selection are to be found on the companys web sites snd in the company's literature. The formulae and technical parameters discussed on those web sites and in the companys literature are for your guidance only and we earnestly suggest that unless you are absolutely certain of the designation of the units you require hat you complete and sign our Questionnaire.

Hydropneumatics products supplied by us are normally designed to be precharged with clean dry oxygen free Nitrogen 'OFN'.

Warning

In view of the Occupational Safety and Health Legislation of 1970 we advise you to order units with the gas rupture disc for safety overload protection at between 1.7X and 3X working pressure. The ratio between the designed burst pressure and working pressure of any industrial unit pressure may be as high as 4.4:1 and fail-safe leak off pressure and working pressure is 4:1. Units are thus designed to lose their energy storing gas before a total failure pressure can be reached. They must not be clamped or mounted in any way which will restrict this fail-safe, but this in no way relieves the necessity to install a direct acting relief valve which must be able to fully open by 1:1x working pressure adjacent to any pressure vessel. The maximum stated working pressure must not be exceeded at any time. One unit per batch of bodies or one percent of like units produced are tested to destruction. Units are generally inspected for corrosion at least every 20 months depending on environment. Each unit is pressure tested to 1.5 working pressure, before shipping, and is also gas leak tested. Any additional over-pressurization is expressly not permitted under the guarantee or products liability policy.

SUITABILITY FOR PURPOSE - Please GOTO link [ /terms/conditions.html ]

SUITABILITY FOR PURPOSE

I. When dealing with Applications or Project Engineering, it is assumed that they are aware of what is normally expected from hydro-pneumatic and/or pressure products and their parts of any particular type. In such dealings, the company's engineer an d sales personnel merely state the nominal volume, the maximum working pressure and the port size of the unit involved; there is no guarantee of the performance or safety of the unit supplied under such circumstances unless the company's questionnaire has been fully completed and signed.

II. When dealing with procurement executives and their assistants we must assume that they have been fully briefed by their engineering staff.

III. In cases where a total concept design study does not appear to have been undertaken. If the customer requires a guarantee on the performance or a certificate on the safety of the unit, a full disclosure of all the facts known by the customer and his user and all the sources of information which will help to complete the disclosure, must be given to the company. Pressure products are generally capable of exhausting or accepting their full rated volume at any rate of flow entirely dependent upon the pressure rise or fall in the system to which they are attached. Their specific performance is, therefore, dependent on:-

PARAMETERS

1. The liquid to be used. (a) The information given in the company's catalog, sales literature, drawings, quotations, or by its sales and engineering personnel as to compatibility is offered only for your convenience, consideration, investigation and verification. The company and/or its personnel cannot accept liability for chemical attack as our clients or their consulting engineers being main system engineers or main component contractors are taken to be far more conversant with the compatibility of materials to their process, than this company's. Advice passed on by us as a result of any membership of Rubber & Plastic Research Association shall not incur us OR that association any liability. In the event of any doubt we will be happy to supply at a nominal charge samples of suggested materials of construction for immersion /temperature/compatibility tests to be carried out. (b) Its specific gravity. (c) Its viscosity. (d) The temperature range over which it works. (e) The acidity - alkalinity - abrasiveness - solvent nature and general compatibility.

2. The fluid pressure supply. (a) Its flow rate or multiples of flow rate. (b) The time taken for its unloading and loading valves to respond. (c) The pressure differential which it is capable of creating. (d) The maximum pressure to which the direct action relief valve or burst disc can be set and its position in the system.

3. The pipework or ducts which are connected to it. (a) Its length or multiples of length. (b) Its diameter or multiples of diameter. (c) The flow friction that it may create, dependent upon the number of bends, elbows, etc.

4. The position of the unit. (a) Whether it is fitted into the duct or (b) Whether it is 'T'd' off from the duct.

5. The draw off from the system. (a) The number of outlets that are drawing off. (b) The pressure drop/flow rate which occurs at these outlets. (c) The instances of these requirements. (d) The total cycle time relationship in which these instances occur. (e) Any dwell time between cycles. (f) The speed with which the outlet control valves work. (g) The number of times per annum that the system will be shut down.

6. Boyle's Law (isothermal) or adiabatic (dependent upon the flow rate involved). (a) The total gas volume contained in the units. (b) The total gas volume contained in the units plus the total gas volume contained in any attached back up vessel system.From the above parameters, the proposed supplier will draw a suggested design specification which may be altered, re-dra wn or amended by the customer, but must be signed by the customer, after which it shall form the basis of the supply contract between the companies or individuals involved.

The above procedure is merely normal practice for the supply of pressure vessels to the codes which have been drawn to cover them. As there is no code in existence specifically covering pulsation dampeners, shock alleviators, pump controllers, liquid line silencers, accumulators, sample bombs, and similar hydro-pneumatics equipment, this has been compiled, it is not in any way mandatory, but it forms part of this Company's Standard Terms and Conditions of Supply.
