What is Hot Expanded Seamless Steel Pipes

The hot expanding steel pipe is hot expanded seamless pipes, which is relatively low density but the contraction of the strong steel pipe (seamless pipe) can be referred to as thermal expansion. A process of skew rolling or drawing method to expand the pipe diameter.

Steel pipe thickening in a short period of time, can produce non-standard and special types of seamless tubes with low-cost and high production efficiency, the current international developments in the field of tube rolling.

Hot expand pipe is by expanding the diameter of pipe to finish processes - thermal expansion process of the production of steel pipe. Hot expansion pipe are commonly referred to hot expanded seamless steel pipes.

So far, the thermal expansion carbon steel pipe production technology is relatively mature, the level of equipment and methods of thermal processing also has made substantial progress. From billet to the basic technological principle is still tube rotary piercing or pressure perforation as a primary means of preparation of the waste pipe, and then by the subsequent thermal expansion of the process to achieve the reduction of wall and expanding.

As smelting, rolling pipe main line extension of the thermal expansion pipe, its production and practice has been a very wide range of applications to fill the major steel production at home and abroad the lack of some special models of large-diameter thin-walled steel pipe blank, but improved production technologies, and control various parameters of the thermal expansion pipe accuracy still requires further research and improvement of China's steel enterprises to strengthen cooperation to jointly research study to improve the thermal expansion of steel production standards, in order to further promote the development of China's steel industry.

Changsha Xiangjia Metal Materical Co., Ltd. the Steel Pipe Division of ADTO GROUP, is one of the leading manufacturers of steel pipe in China. We specializes in manufacturing seamless steel pipe, ERW steel pipe, square & rectangular steel pipe, OCTG pipe, ect. in various grades and sizes.

When Should Personal Protective Equipment (PPE) Be Used in Healthcare

Personal protective equipment (PPE) is disposable clothing worn to create a barrier between blood, bodily fluids, or respiratory secretions. PPE is often used to prevent cross-contamination, such as in food preparation or for safety when using chemicals. Because of this, PPE is extremely important in care homes and healthcare. When should PPE be used in healthcare? Most commonly, personal protective clothing in healthcare settings are used for infection control. PPE acts as a barrier between infectious materials and your skin, nose, mouth or eyes. This barrier has the potential to block the transmission of contaminants from blood, bodily fluids or respiratory secretions. PPE also helps to protect those at a high risk of contracting infections, such as those with a medical condition, for example immunodeficiency, from being exposed to potentially infectious materials brought in by staff or visitors. PPE is designed as disposable clothing so it can be effectively removed an...

The Difference Between Seamless Steel Pipe and Seam Steel Pipe

Seamless steel pipe , as the name suggests, is a pipe without a seam or a weld-joint. Seam steel pipe are generally welded with a seam. 1. Different Processing Technology: seamless steel pipe is made of high quality carbon steel or alloy steel. The processing technology of seamless steel pipes are cold drawn and hot rolled, and seam steel pipe are generally welded. 2. Different Uses: seamless steel pipes are mainly used as pipelines for conveying fluids, or structural parts in machinery industry, and seam steel pipes are mainly used in construction industry, such as low-pressure fluid, like water, gas, compressed air. But when must to use pressure pipes, seamless steel pipes is the better choice. 3. Different Pressure-bearing: the maximum working pressure that the seamed pipe can withstand is within 20 kg, which is the safest range of use. It is generally used for low-pressure fluids such as water, gas, and compressed air. Seamless steel pipe can withstand ultra-high pre...

Guidelines for Wearing Face Masks

If you’re considering wearing a mask to protect yourself against infections, there are two types you should know about. Surgical face masks and respirators Surgical face masks are fairly loose-fitting, disposable masks, these masks prevent large droplets of bodily fluids that may contain viruses or other germs from escaping via the nose and mouth. They also protect against splashes and sprays from other people, such as those from sneezes and coughs. But they aren’t enough to filter out viruses. Masks worn over the face are also unable to protect you from getting airborne virus particles, from a cough or sneeze, into your eyes. Respirators, also called N95 respirator masks, are designed to protect the wearer from small particles in the air, like viruses. The name comes from the fact that they can filter 95 percentTrusted Source of airborne particles. N95 masks are also often used when painting or handling potentially toxic materials. Respirators are selected to fit y...
