In fact, the name of flange is a transliteration. It was first put forward by an Englishman named Elchert in 1809. At the same time, he proposed the casting method of flange. However, it was not widely used in a considerable period of time later. Until the early 20th century, flange was widely...
The forged flange and the cast flange are two common flange types in the market. Cast flanges have low cost, low technical requirements, a short mass production cycle. Forged flanges have a slightly higher price and good quality. Let's focus on analyzing the pros...
In the production of forged flanges, it is often necessary to heat the flange blank at high temperature and then forge it by a hammer. Through constant blows, the density of the flange blank is continuously increased. And then the flange is produced by shaping and drilling. There are certain risks...
What is a Lap Joint Flange/Loose Flange? A lap joint flange is used to cover the end of a pipe with flanging, the steel ring and other processes. The steel ring or flanging is a sealing surface, and the function of a flange is to press them tightly. It can be seen that the lap joint...
The application of flange plays an important role in many aspects, including petrochemical industry, energy industry, scientific research and military industry. However, in the reactor of refinery, the production environment of flange is very bad, and the performance of flange must be excellent, because...
Nitric acid spot test: A notable feature of stainless steel flanges is inherent corrosion resistance to concentrated nitric acid and dilute nitric acid. This property makes it easy to distinguish from most other metals or alloys. 1. Copper sulfate spot test: Copper sulfate point test is the simplest...
A flange is used for attachment to another object, for instance, the end of a pipe. It can also be used for connection between two equipments, e.g. reducer flange, which is used for connection between the motor and the reducer, as well as the reducer and other equipment. According...
During flange casting, the liquid metal is filled with a mold and solidified while rotating. The flange casting has the following characteristics: liquid metal can form a freely selected hollow cylindrical surface in the mold, so that hollow castings can be cast without a core, thereby greatly simplifying...
Flange is a disc-shaped connecting part that is connected between pipe ends and closed at the same time. It is the most common in pipeline engineering, such as the connection of ventilation pipes. Flange materials include carbon steel, low alloy steel and stainless steel. Among them, stainless steel...
