PVC fittings: the possibility of using the characteristics of materials | |
|
Despite more than 10 years of experience our company in the supply of industrial equipment from polymers still remain cautious when considering the polymer as an alternative to traditional steel systems. The main reasons for caution in going to the plastic, depending on the awareness, may include:
Over the long history of existence, our company has accumulated substantial experience in the supply of PEX & PVC systems (pipes, elbows, couplings, fittings, trees, instrumentation) in a variety of industries. Years of work in close cooperation with engineering companies and directly with end users have identified the main range of issues related to the transition to polymer piping systems. So, let's begin. Myth 1: Lack of experience in working with polymers in Canadian companies A number of Canadian engineering companies, such as Bow (Canada) and many others, have accumulated to date, some experience in design and installation of process piping made of polymers, in cooperation with the manufacturers of these systems have in Currently, substantial support to enterprises-customers. Very often, these companies do a better job with the design than the actual design institutes, since they receive more and practical experience in the activity. They are self-assembled engineered production lines, can evaluate and improve the result. Seminars conducted Representative for Glynwed Rush of 2009 in the leading Russian research institutes, suggests a tendency to "cure" the domestic industry. Years of experience of their staff, a willingness to consider new systems and materials, coupled with continuous information and technical support from our side will substantially upgrade the existing production, reduce production costs, increase service life of components and assemblies. Myth 2: "The absence of regulatory frameworks (Installation, regulations and rules) Indeed, the expansion of industrial application of PVC piping systems in Canada is seriously complicated by the partial (CH 550-82 still is) the lack of regulatory framework for the equipment made from polymers. Design institutes and engineers are graduates of high schools initially, as a rule, are not familiar with the peculiarities of the design and use of modern PVC pipes. This is due, primarily, with some lag the national science and industry, formed largely from the early 90's, while European companies have continued to actively develop the direction of technological pipelines of polymers. Currently, the main regulatory instrument for the design and construction of industrial plastic piping is CH 550-82 - "Instructions for the design process piping from PVC pipes. The manual design process piping from PVC pipes. Additional information can be found in a series of reference materials Publishers VNIIMP "" PVC pipes and modern technologies for construction and repair of pipelines, ed. These sources is still little known medical specialists. In large measure the information gap is filled materials provided by foreign producers directly concerned in the development of their products in Canada. First of all, it concerns the description of the types of polymers and polymer products, which are absent in the domestic sources, instructions for installation, data on the chemical resistance of polymers to various types of chemical compounds. Upon request, we are ready to send executives on designing piping systems on the example of PVC, which highlights the most frequently asked questions about the calculation of poles, installation of expansion joints, etc. To aid in the calculation and design of polymeric pipes are special software tools. Among them, a free program FIPlastiCAD - database of 3D models of products in 5 different formats (including. Dwg,. Dxf) with integrated technical catalogs and means of calculation supports, hydraulic shocks, changes in the length of the polymer pipe, depending on the temperature, etc. Another program designed to facilitate the design of polymeric pipelines - Kemy (electronic directory of chemical resistance of polymeric materials, developed on the basis of experimental data of the plant FIP (Italy). The above tools are free and are an integral part of our support of designers and engineers, in addition to complete technical catalogs. Myth 3: "The absence of Canadian certificates for products" The requirements of some industries to polymer pipeline systems presuppose the existence of not only the certificate of conformity, but also permits RTN on the whole line of products supplied. Not all foreign manufacturers of polymer piping systems find it necessary to have such permission. Our company is a confirmation of the reliability of the delivered elements of the pipeline (pipes, fittings, valves, instrumentation of the polymers) conducted a comprehensive product certification, and has in its arsenal, on the use of equipment in areas with increased seismicity. Myth 4: The absence of full-fledged Canadian technical catalogs " An important factor in the transition to the design of polymeric pipes produced by the foreign manufacturer, is the presence of French language technical catalogs. We are often faced with a request to send catalogs, and as a result, in 2009, were technical catalogs fittings and accessories made of PVC, CPVC, PP (PPH100), PVDF *. * More listed polymers and their properties will be described below. Myth 5: "Polymer - unacceptably brittle material", or "The Myth of ubiquitous Vasya-mechanics, and an adjustable wrench" Argued that the polymers - a fragile, unreliable material. Here are some examples of the general properties of polymers and supporting the possibility of industrial application of PVC pipe, CPVC, PP:
