Russian Metric System

Posted by Toni - September 20th, 2021

This is easily explained, since the Russian metric system is based on the outer diameter (for steel welded tubes), or the equivalent diameter (for water and gas steel pipes), while the system operates inch inner diameter. Get all the facts for a more clear viewpoint with Fred Lynn. Ie a 'pipe-inch' – it's the outer diameter of the pipe inner diameter which is about one inch ordinary. Accordingly, for the "real" outer diameter "pipe in." must be added the thickness of the walls of the pipe 2 (light weight, ordinary or rigid wall). Transcript inch system of ordinary water and gas pipes (translated to metric and vice versa): Tube 1 / 2 inch – 15mm (Pipe dn 15) Pipe 3 / 4 inch – 20mm (tube dn 20) Pipe 1 inch – 25mm (tube dn 25) pipe 1 1 / 4 inch – 32mm (tube dn 32) pipe 1 1 / 2 inch – 40mm (Pipe dn 40) 2-inch pipe – 50 mm (tube dn 50) The legacy of the inch system of units of Russia got to include not only water and gas pipes, and carvings, which they cut. Water and gas pipes according to gost 3262-75 made with 1) normal, 2) increased accuracy of rolling, and in both cases, tolerances by weight shall not exceed 8%.

The length of pipe in the production can be from 4m to 12m, depending on the tu manufacturer, rolling conditions, the length of workpiece (strip), the buyer's order, etc. Pipe dn 15 can be performed without the black coating and a galvanized coating that is applied by thermal diffusion or electrolytic galvanizing. The galvanized coating is better resists aggressive media, the process of rusting, and therefore the life of galvanized pipes higher than the usual black water and gas pipes. Accordingly, the cost of galvanized pipe is higher than the water-gas steel pipe. dn 15 pipe is used for piping (in the industrial and civil engineering), heating systems, in as a "box" for the laying of cables for electrical works, etc. cc anta has a wide range of water and gas pipes at our own warehouse at St. Petersburg, highway, 4. Pipe dn 15 are readily available at an attractive price.


XYZ Customer

We will consider a logical component of the XYZ-analiza.A it is here that just runs and further specification of the old customers. This group of customers is constant and is divided into more customers for three subgroups. The division is carried out by means of mathematical statistics on the basis of frequency of occurrence of the trait. Ie based on the processing of a sufficiently large number of sales data highlighted subgroups that are conventionally can be called as "often buy" customers, customers that buy, with an average frequency and "rarely buy." In this case, the subgroup, such as "often buy" can get not only customers who buy every month, and with some other frequency. It will all depend on the initial data. In addition, it also can be released and the new subgroup.

For example, a customer lost, ie a buyer who purchases the frequency falls below boundaries of the third category. And even if he occasionally does some shopping, then he still considered lost. While at the logical level a lost customer is one who already does not make purchases at all. "New" client in this case, too, has a frequency of purchases below the lowest, but he seems to rise from zero in the ascending as opposed to lost, which was already behind enough intense history of purchases. In general, the scheme breakdown of its customer base with XYZ-analysis can be illustrated by the following figure: Figure 2 Segmentation of the customer base by XYZ-XYZ-analysis analizOsobennosti Initially this method was developed for analyzing customer base, but then it was used for the analysis of product assortment.
