 Classification of products and services in Vlist


 طبقه بندی کالا در وندورلیست

Our technical team has spent lots of effort and energy to study all products and services of petroleum and energy industries. Besides, they have studied a few Iranian and non-domestic well-known vendor lists. All these endless efforts and studies along with market studies make it possible to prepare a precise and comprehensive classification of products and services. This tree-shaped classification includes different types of a product or service regarding their usage in different fields. Tree-shaped classification has this advantage that you can search products or services related to each other and avoid those irrelevant ones that are similar in names, but different in usage. So, comprehensiveness and exactness of information are two unique and premier attributes of Vlist portal.

To have a better understanding, we compare Flow Meter classification of Vlist portal with some of well-known domestic and non-domestic vendor lists:

Flow Meter classification in KOMPASS website

KOMPASS is one of the most visited web sites about sourcing services. This website has not any tree-shaped classification and based on your searched words, it proposes some results. Because of this, if you search for Flow Meter in this site, it will give you some suggestions that are shown below. 2 first search results are medical equipment for blood pressure and flow that are in search results because of similarity of their names. Besides, gas flow meter and water flow meter are some general counter devices and in Vlist portal, they are apart from industrial flow meters. Another problem is that some items are shown together and client will be confused to find exact product. For example magnetic and electromagnetic flow meters are two different products and they should be separated from each other

Flow Meter classification in DIRECTINDUSTRY website

DIRECTINDUSTRY is one of the most famous B to B (business to business) companies in in the world. This web site has an almost proper tree-shaped classification that helps in search results. But there are some overlaps that may confuse clients. For example, volumetric flow meter is introduced as a product, but there is not such a product at all! Volumetric flow meter tells us how flow rate will be measured, like mass or volume or speed of flow. Besides, despite of Vlist portal, some of flow meter types are not available in DIRECTINDUSTRY.

Flow Meter classification in Pars Oil and Gas Company Vendor list (NIGCENG)

POGC is one of the most important EPC contractors and field management companies in Iran that plays a major role in petroleum industry of Iran. Its vendor list includes just 8 types of flow meters, regardless of their different types. For example, if we need an ultrasonic flow meter, it must be clear that what type of flow (liquid or gas) is needed to be measured. Each type needs its special flow meter and it may have different sources. This may encounter some problems of sourcing for procurement department.

Flow Meter classification in Iranian Offshore Oil Company Vendor list (IOOC)

Like POGC, this vendor list has not a detailed classification of product and procurement departments must consume lots of time and energy to find proper suppliers.

 طبقه بندی فلومتر در IOOC













Flow Meter classification in National Iranian South Oil Company Vendor list (NISOC)

NISOC includes just a general activity for flow control equipment that is incomplete and because of this, procurement must have two phases. It is necessary to ask all suppliers of flow meter if they have a specific kind of flow meter, and then they should negotiate with selected ones.
