Restoration, processing and cleaning of used pipes

() | Преглеждания: 364 |

A distinctive feature of any used pipe from a new one is the mandatory restoration and restoration work. Such work includes cleaning the outer and inner surfaces, grinding, dismantling of fasteners, welding and welding, applying new chamfers. Processing can be either partial (affects only some areas) or complete (the entire body of the rolled product is restored). All these processes are divided into cheap and more expensive, and their application is dictated by wh...

Application of used pipes

() | Преглеждания: 345 |

Several decades ago, no one even thought about reusing old and dismantled pipes. The growth in popularity of used pipes was provoked by a significant rise in the cost of raw materials and the process of production of new rolled products. This was the impetus for the development of a new business for the restoration and sale of pipe products that were in use. Why is this beneficial? First of all, because a used pipe is several times cheaper than a new one. This is...

Situations are not uncommon when pipe metal products can be stored in a warehouse for a long time until they are sold. However, it happens that products do not go into use for too long and lose a number of their properties. In such cases, such a pipe from the new category falls into the used category, namely the old one, and cannot be used without undergoing special restoration work. What kind of negative changes might happen? The main and most significant is cor...

How to determine the mass of a forging from a drawing?

() | Преглеждания: 541 |

An accurate calculation of the weight of rolled metal according to the drawing is necessary for accounting, as well as determining storage and transport costs. In addition, this will allow the buyer to determine whether the product claimed by the manufacturer is true. Forgings can be different config. To accurately calculate the mass of such a workpiece, it is necessary to know two parameters: the density of the steel from which it is made, as well as the volume of the product. And if the density of s...

On what basis is a forging blank selected?

() | Преглеждания: 338 |

The forging itself is an intermediate rough workpiece obtained by one of the forging methods and intended for further processing in order to obtain a finished product. In turn, forgings are produced from primary billets, which are processed on forging or stamping units (presses, hammers, etc.) There are two main principles by which a blank for forging is selected: Minimum material consumption during forging and subsequent machining. Minimum labor costs and simplification of the technological proce...

Basic requirements for forgings

() | Преглеждания: 472 |

The range of steel forgings is quite extensive. They may differ in their profile, dimensions, material of manufacture, surface quality, heat treatment, etc. In turn, the characteristics of forged metal products are determined by its applications, so the requirements for forgings can be very different. In general, the technical requirements for the production and range of forgings are regulated by several established state standards. Here is a list of the main documents currently in force in Ukraine: GOST 8479-70 "Fo...

Forgings and stampings: differences and features

() | Преглеждания: 446 |

Forged metal is obtained in two main ways: forging or stamping. In the first case, the product is given the necessary shape through gradual processing with hammers, presses, etc. In the second – the workpiece is placed on the matrix, after which it is squeezed by the press. As a result, the finished product is received almost instantly. There are three types of forgings: Free forging on hammers and presses. Forging with the use of backing dies for the production of parts of a more complex co...

Application of forgings

() | Преглеждания: 578 |

Forgings – these are blanks obtained by forging methods and subsequently used for the production of various parts. The main feature of this type of rolled metal is that the forgings very accurately correspond to the products made from them. As a result, chip waste is kept to a minimum during metalworking, which saves material. In addition, the processing of a forging is relatively simple and often consists of only polishing and grinding the surface. Thanks to this, forgings are widely used in va...

Forgings – these are draft blanks, from which subsequently using the preliminary and final metalworking produce various parts. Advantages of forged rolled metal products: affordable cost and maximum conformity of dimensions and shapes to the required product. Due to the fact that forging exactly matches the prototype part, its processing is simplified and chip costs are minimized. What are forgings? First of all, this type of rolled metal is distinguished by its profile: they are round and rect...

Calculation of the weight and volume of the forging

() | Преглеждания: 2757 |

When drawing up design and technical documentation, as well as when placing an order for rolled metal, it is necessary to accurately calculate the required quantity. Since the weight of rolled products is the main equivalent when it is shipped, this parameter is determined. Forgings come in round and square sections. To determine the weight of a round forging, you first need to calculate its volume (according to the cylinder volume formula): V = πr2h, where r – forging radius (half the diam...

Forgings – quite demanded type of metal rolling. They are draft blanks that correspond very precisely to the dimensions and shapes of the part. To give the forging the required dimensions, it is subjected to mechanical processing, which is also called preliminary. In turn, heat treatment (hardening, tempering, annealing, etc.) is also called final. Types and features of pre-treatment of forgings Mechanical (roughing) processing of forgings is carried out in machine shops. They process workpiece...
