The forgewelding process is one of the most efficient methods of making tube and pipe from 12 to 24 in. diameter, but its not limited to this range. An ERW mills capability can be expanded by adding a coldstretchreducing section, allowing it to make smaller diameters.
The mother tubes, which have been reheated and descaled using a water blast, are deformed in a stretchreducing mill with 28 stands, until they have the final desired diameter and wall thickness. Various controls ensure optimal yield of the mother tube and that the required tolerances are met.
The seamless pipe and tube making process begins with a steel plug, steel slug or billet that is heated to molten temperature and pierced on a piercing mill to initiate the elongated and hollow nature of pipe. The pipe then passes through a stretch reducing mill to further resize and work the metal.
Stretch Reducing Mill SEAMLESS TUBE MILL After dozens of installations of Piercing Mills, Rotary Expanders, Sizing Mills Stretch Reducing Mills, Pipe Straightening Machines, Hot Pilger, Accu and Assel, China has emerged as a more and more important supplier for 2roll retained mandrel mills MPM and 3roll retained mandrel pipe mills.

Stretch reducing mill. The stretchreducing mill represents the third main forming step of seamless tube production. The heated hollow is stretched to achieve the final diameter and wall thickness by up to 30 driven roll stands without internal tool through several driven roller stands.
This paper shows the drive solution, the speed references calculation and the automatic control of all speeds range for the assembly of the 24 stands belonging to a stretchreducing mill for

The potential of process optimization in stretchreducing mills Automation in seamless tube production with CARTA neo When it comes to planning and optimization in the production of seamless tubes, the CARTA system has made a name for itself on the market in over 30 years.
The following points highlight the six main mills for reducing tube thickness and sizing. The mills are 1. Pilger Mill 2. Mandrel Mill 3. Plug Mill 4. Reeling Process 5. Assel Mill 6. Stretch Reducing Mill. 1. Pilger Mill The tubular shells produced in piercing process are further processed. Pilger mill is commonly used after rotary piercing.
Steel Pipe and Manufacturing Processes Introduction. The advent of rolling mill technology and its development during the first half of the nineteenth century also heralded in the industrial manufacture of tube and pipe. Initially, rolled strips of sheet were formed into a circular cross section by funnel arrangements or rolls, and then butt or
apparition the first reducing mill was built in 1920 the stretchreducing mills construction was improved successively, with remarkable consequences in terms of pipe quality and productivity. Thus, modern stretchreducing mills allow a pipe wall reduction of up to 3540 without any interior tool and an outer diameter reduction of
Hot Stretch Reducing. Hot Stretch Reducing is an additional process for ERW products. This process involves taking the ERW tube, heating and passing the product through a series of rollers that reduce the size of the tube in one relatively fast operation. This is advantageous for customers, improving size ranges that PTC Alliance can offer.
