Deliveries and Collections
How do I arrange collection of EffecTech cylinders?
In order to arrange collection of cylinder(s), please contact us with full collection details (as shown below). We will be able to advise if there is an outstanding collection for the cylinders, or quote to arrange the transport back to us.
Information required to arrange a collection
- Pallet/frame dimensions
- Photo of the packed pallet/frame
- Cylinder details – size and contents (or certificate numbers)
- Collection address and site contact name and telephone number
General rules for cylinder collection
- Cylinders must be packed securely onto a pallet prior to arranging the collection
- Couriers will not wait for cylinders to be packed and unpacked
- All cylinders should be fitted with valve caps or guards and ideally also have cylinder plugs in the valve outlets
- Cylinders should not overhang the ends of the pallet
- Collections are charged per pallet
Is it ok to pack cylinders lying down?
Yes, wherever the contents are entirely in the gaseous phase. A gas will always fill the container it is in and exert pressure on all areas of the cylinder wall equally, regardless of the orientation of the cylinder. Therefore, there is no increased safety risk from the cylinder contents if the cylinders are packed horizontally for transport. In fact, due to the cylinders low centre of gravity, packing horizontally provides more stability during transport.
The only increased risks for horizontal cylinders with entirely gaseous content are due to the physical position, size and shape of the cylinders. i.e. manual handling to lift the cylinders on and off the pallet or more potential for damage to the valve when they are low to the ground.
Valve damage is mitigated by the use of valve guards and caps and personnel should be fully trained in the correct manual handling technique.
Please note this advice may not be applicable for cylinders which contain both gas and liquid and so each type of cylinder used/stored should be assessed separately.
Do you collect cylinders from outside the UK?
It is generally preferable for customers overseas to arrange cylinder return themselves. However, if you require any advice or assistance, please contact us and we can make some enquiries with regards to what services are available.
What is the UN number and HS code for my calibration gas mixtures?
The UN number for all of our flammable calibration gas mixtures is UN 1954. The HS code is 27112900. These will be the codes for dangerous goods purposes. Please enquire should your mixture be non-flammable or a pure gas.
Disposables, detectors and alarms
Do you supply disposable cylinders?
No, EffecTech does not offer disposable cylinders.
Do you supply detectors, instruments, alarms etc?
No, EffecTech does not offer instrumentation or gas measurement equipment but can offer services to calibrate instruments and sensors used in natural gas quality measurement.
Cylinder sizes available
What size cylinders do you stock?
Requesting a quotation and placing an order
What information do you need to provide a quotation?
For a calibration gas, we require a full composition, cylinder size and usage temperature in order to provide a quotation. If you require EffecTech to arrange delivery, please also include a full delivery address.
For ISO 10723 evaluations, we would only require the site name and instrument details for instruments we have calibrated before. For new instruments we require completion of a client questionnaire for each instrument – please contact us for more information.
How do I place my first order?
We require a purchase order detailing the delivery address, pricing and invoicing details. We require all first-time customers to pay in advance via a proforma invoice. We do not accept credit cards.
What are reference conditions and why are they important?
Reference conditions are the conditions (e.g. temperature and pressure) at which properties are calculated. Your certificate may include physical properties (e.g. calorific value, density) that have been calculated at primary and secondary reference conditions. The inclusion of both primary and secondary reference conditions enables different customers that may have different reference conditions to calculate and compare results.
What are cylinder storage and usage temperatures?
The certificate of calibration should state a usage temperature range. This is the temperature the cylinder must be maintained between when in use, in order that the contents remain homogenous.
The certificate of calibration should also state a storage temperature range. This is the temperature the cylinder must be stored between when not in use, in order that the contents remain in a single (gas) phase.
Is it possible to change valve type once I have placed my order?
No, it is not possible to change a valve once it has been fitted to the cylinder and filling has commenced.
What’s the difference between ISO 10723 and ISO 17025?
The International Standards Organisation (ISO) describes the two standards as follows:
ISO 10723:2012 Natural gas — Performance evaluation for analytical systems, is a standard which specifies a method of determining whether an analytical system for natural gas analysis is fit for purpose.
ISO 17025:2017 – General requirements for the competence of testing and calibration laboratories, is a standard that allows laboratories to demonstrate that they operate competently and generate valid results.
EffecTech are accredited to ISO 17025 by UKAS to calibrate natural gas analysers in accordance with ISO 10723.
