General Engineering – Volume 5 – Issue 1


There are many standards developed for various products and services and manufacturing. For e.g IS, BS, DIN, AWS, Agg Mark and so on . They basically serve the purpose of some agreement between buyer and supplier. When a manufacturer manufactures a product to a certain standard , it gives assurance to the buyer, minimum quality of the product. ISO 9000 is not a standard for a product but it has series of management system standards, that have been created to help organisations ensure that they meet the needs of their stakeholders, such as customers, shareholders, personnel, etc., while at the same time complying with statutory and regulatory requirements. This is becoming very popular now to get organization certified to ISO standard. In our first article we are focusing on this ISO standards in details.

We come across lot of civil structures while traveling on any road. The bridge is a very important component of any road. We come across number of such structures in our life. When something goes wrong with such structures, our life became miserable. To avoid such incidences lot of effort are being taken by various engineers. In our next paper we are discussing the issues related to the type of bridges, their design, construction and maintenance.

Textile industry is a very huge industries with various processes, right from making yarn / fibers , dyeing, knitting, weaving and so on .In last few issues we have seen some aspects like Dyeing, Pre-treatment etc. Because of impurities, even after desizing fabric have pale appearance.This is mainly due to the presence of natural coloring material like pigment .These pigment cannot be removed easily. The only way to tackle these pigment, is to decolorize them using suitable oxidizing agents. This will make the fabric in a super white form.This process of discoloration of natural pigments is called bleaching. In this issue we are discussing this interesting process of bleaching .

Heat exchanger is a device , which is used for transferring heat from one fluid to another through a separating wall. These are extensively used in chemical, food and process industries. In our last issue we have studied the various types heat exchangers that are being used today. In this issue , we will look in to the design aspects of heat exchangers particularly Shell and tube type heat exchangers.
