Key Equipment in Seamless Steel Pipe Production - Pipe Billet Heating Furnace

图片
According to the different   seamless steel pipe   production processes, seamless steel pipe production equipment can be used in a variety of ways. However, whether rolling, extrusion, top pressing or spinning and other seamless steel pipe manufacturing processes are used, billet heating equipment is required. Therefore, in the seamless steel pipe production equipment, the billet heating equipment is particularly critical. Now let's discuss the billet heating furnace in seamless steel pipe production equipment. Seamless steel pipe round steel or billet heating furnace is one of the crucial equipment in the production of seamless steel pipe, which must be heated to 1150 degrees round steel after perforation to become gross, for the subsequent shaping, probing, marking and so on to do the most basic work. The basic configuration of seamless pipe billet heating furnace is as follows: 1. Medium-frequency power supply system: 200KW-6000KW, with an hourly output of 0.2-16 tons. ...

The Essential Equipment for Seamless Steel Pipe Production

图片
Seamless steel pipes   are manufactured by rolling steel ingots into round bars, then piercing them to create tube blanks (also known as rough tubes), which are further processed into seamless pipes through processes such as hot rolling, cold rolling, or cold drawing. The production of seamless steel pipes involves various production processes and equipment. Whether it is continuous rolling, cyclic rolling, mandrel rolling, or extrusion production processes, it is essential to heat the round bars or tube blanks to the required temperature using an induction heating furnace before feeding them into the rolling or extrusion machines to produce seamless steel pipes. Subsequent processes include straightening, cutting and marking the pipes, and bundling them for storage. The equipment for seamless steel pipe production typically includes a cutting saw, tube blank heating equipment, induction heating furnace, taper piercing machine, Accu-Roll mill, 8-stand three-roll micro tension redu...

The Differences between Hot-rolling and Cold-rolling of Spiral Pipes

图片
Both hot-rolling and cold-rolling of   spiral pipes   are processes for shaping steel sections or plates, which have a significant impact on the microstructure and properties of the steel. In steel rolling, mostly hot-rolling is used, while cold-rolling is mainly utilized for manufacturing small-sized sections and sheets. First, hot-rolling can disrupt the casting structure of ingots, refine the grain size, and eliminate defects in the microstructure, thereby making the steel texture denser and enhancing mechanical properties. This improvement mainly manifests in the rolling direction, making the steel to a certain extent no longer isotropic; bubbles, cracks, and porosities formed during pouring can also be welded under the action of high temperature and pressure. Second, cold-rolling refers to processing plates or strips into various forms of steel through cold-working methods such as cold-drawing, cold-bending, and cold-extrusion at room temperature. It features rapid formin...

The Difference between Hot Rolled and Cold Rolled Q235B Square Pipe

Q235B square pipe   is one of the products with increasing demand, especially in the fields of petroleum, chemical, power generation, automobile, shipbuilding, construction and environmental protection. The annual consumption is about 700,000 tonnes. Domestic Q235B square pipes have covered the variety specifications of the world's standards, and the specifications and varieties of shaped pipes are more than a hundred kinds. Next, we will discuss the differences between hot rolled and cold rolled Q235B square tube: 1, Cold-rolled structural steel allows for local buckling, thus better utilizing its load-bearing capacity, whereas hot-rolled structural steel does not permit local buckling of the cross-section. 2, Hot rolled steel and cold rolled steel residual stresses of different reasons, so they are also very different distribution of the cross-section. Cold-formed thin-walled steel section on the distribution of residual stress is curved, and hot-rolled steel or welded steel sec...

Understanding the Manufacturing Process of Alloy Steel Seamless Pipes

Alloy steel seamless pipes   play a crucial role in various industries due to their exceptional strength and durability. In this article, we will delve into the intricate process of manufacturing these pipes. Alloy steel seamless tubes are crafted by incorporating different metals and non-metals into carbon steel. The specific composition of alloy steel is tailored to meet the desired properties and performance requirements. For instance, the addition of manganese results in alloy steel with distinct characteristics compared to alloy steel infused with copper. The selection of additives is pivotal in determining the final quality and functionality of the alloy steel. The manufacturing process typically involves melting the base materials in a furnace at high temperatures to achieve a homogeneous mixture. This molten alloy is then shaped into seamless pipes through a specialized rolling or extrusion process. The pipes undergo multiple stages of heat treatment and precision machinin...
