ERW Steel Pipe

Azerbaijan’s economy has been rapidly growing over the past few years, thanks to the country’s vast oil and gas reserves. With its strategic location between Europe and Asia, Azerbaijan has also become an important hub for the transportation of oil and gas. This has led to a significant demand for high-quality steel pipes in the country, especially those that are coated for added protection against corrosion and other environmental factors. One such product that has gained popularity in Azerbaijan’s coated steel market is Xinyue’s 3LPE (Three Layer Polyethylene) spiral welded steel pipe. This type of steel pipe is designed to withstand harsh environments and is commonly used in applications where corrosion resistance is essential. The 3LPE coating consists of three layers – an epoxy layer as a primer, a polyethylene layer as a middle layer, and another polyethylene layer as an outer layer. This triple-layer coating provides excellent protection against corrosion, impact, and abrasion, ...

Steel pipes are used in a variety of ways, primarily to carry heavy loads in concrete pile casings, protect electrical wires, water and gas, and even support scaffolding. Over time, these metal products wear out. It's best to have a proper maintenance program in place to ensure they last longer. We've listed some simple tips for maintaining the integrity of steel pipes so they last. 1. Avoid Metal-to-Metal Contact It is important to note that when you are laying steel pipe for the first time, you need to have a strategic plan for placing the steel pipe in a way that minimizes contact with other metals. Continued contact of the tube with other metals can cause frictional damage such as scratches and dents. In addition, metal-to-metal contact can also cause corrosion. Keeping seamless pipes a reasonable distance from each other will help prevent this from happening. 2. Reduce Seamless Pipe and Steel Movement Loosely-arranged or dangling pipes are another reason for early damage t...

Outer Diameter: DN80-DN2000MM Type Of Connection: T type, NⅠ type,NⅡ type, K type, self-anchored, Flange type, etc. Application：Potable water distribution, wastewater treatment, industrial piping, irrigation systems, mining, etc Ductile iron pipe (DIP) is a type of cast iron pipe that is stronger and more flexible than traditional gray iron pipe. It is made by adding nodular graphite to molten iron, which creates a material that is both strong and ductile. The resulting pipe has a high tensile strength and can withstand heavy loads and high pressures without cracking or breaking. Ductile iron pipe is commonly used in water supply, sewer systems, and industrial piping applications due to its durability, corrosion resistance, and versatility. It is also environmentally sustainable, as it is made from recycled scrap iron and is itself fully recyclable. With a lifespan of up to 100 years...

Kyrgyzstan’s steel market is steadily growing, driven by the country’s infrastructure and construction projects. With the increasing demand for high-quality steel pipes, Xinyue Steel has been providing a r...

For carbon steel pipes (cs pipe), it should be degreased first and then pickled, because grease is insoluble in acid. If pickled first, neither the oil stain nor the rust covered by the oil stain can be removed. Degreasing and pickling method for seamless tubes: At present, the tank soaking method is often used in construction, and the liquid level exceeds the outer surface of the pipe by more than 50mm during soaking. Since the oxygen pipeline needs to be degreased, pickled and passivated, generally 4 tanks are made according to the actual pipe diameter. That is, degreasing tank, pickling tank, neutralization tank, passivation tank. Oxygen pipeline degreasing and pickling process is: degreasing→water flushing→pickling→water flushing→neutralization→passivation→water flushing→drying. 1. Degreasing The formula of the degreasing liquid is: every liter of the solution contains 20g-30g of sodium hydroxide, 35g-50g of sodium nitrate, and 3g-5g of sodium silicate. The operating process requir...

1. Before molding work Raw materials that strip, wire, flux. We must go through rigorous physical and chemical testing before it is put. Strip head and tail docking, single or double wire submerged arc welding, in rolled steel by automatic submerged arc welding. 2. The molding process Electric contact pressure gauge to control both sides of the conveyor pressure cylinder pressure to ensure the smooth delivery of the strip, the host is centrally located, so you should always check to adjust the vertical roll (especially around the head), to ensure delivery of the strip edges strict according to the process specified route runs through the meshing point design. By external or internal control roll forming, checking the perimeter, pipe ovality, straightness and other compliance standards, do not meet the requirements, will have to continue to make adjustments until the desired date. 3. The welding process The weld gap control device to ensure the weld gap to meet the welding requirements,...

Precision seamless pipe is a high-precision steel pipe material processed by cold drawing or hot rolling. Due to the characteristics of no oxide layer on the inner and outer walls of the precision steel pipe, no leakage under high pressure, high precision, high finish, no deformation in cold bending, flaring, flattening and no cracks, etc. Therefore, it is mainly used to produce pneumatic or hydraulic components, such as cylinders or oil cylinders. It can be seamless pipe or welded tube The chemical composition of precision steel pipe The strength and hardness of precision seamless steel pipe materials increase, and the plastic deformation recrystallization temperature increases, but the plasticity and toughness decrease. Also known as work hardening. The reason is that during the plastic deformation process of the precision seamless steel pipe, the grain slips, dislocation entanglement occurs, slender, broken and fibrous grains, and the internal residual stress of the precision seamle...
