High strength The welding neck flange is the strongest weld in the pipeline connection. Its strength can be equal to or even exceed the strength of the pipeline itself. Excellent sealing Weld-Neck Flange has high strength and high sealing precision. It is a very solid whole with very uniform stress distribution, so it has high

Recently, major players in the construction world released their financial reports for the second quarter of 2025. Here’s the rundown. Quick Facts • Caterpillar/CAT saw an increase in revenue year over year of $34 million, with a total profit of $137 million. • Deere saw a decrease of 9% in net sales and revenue year

Uncoiling: Hoist the raw steel coil onto the uncoiler for flattening and straightening Accumulating： This step is to achieve uninterrupted production. The uncoiled pipe head and tail are welded together to form an uninterrupted steel strip, and the steel strip edges are trimmed to provide the precise strip width required in the forming and ERW

Bucket teeth are one of those parts that you tend not to think about replacing as much as you would a final drive or sprocket. However, not replacing them as they wear down can compound into higher costs. Worn teeth are less effective at pushing into material and thus can lead to more strain being

Radiators and oil coolers are essential components of any heavy-duty machine’s cooling system. While most people associate radiators with overheating issues in their personal vehicles, the same principles apply—just on a much larger scale—when it comes to bulldozers, excavators, wheel loaders, and other construction equipment. A failed cooling system doesn’t just stop a job; it

Stainless steel tubes are a key component in the petrochemical industry. They are used for fluid transfer and structural support. These tubes are strong, durable, and corrosion resistant which make them suitable for environments where safety, performance and long life are important. These are the main reasons why petrochemical plants need stainless steel tubes: Corrosion

What is AS/NZS 1163 Steel Pipe? AS/NZS 1163 steel pipe is the current standarded pipe used by the Australian and New Zealand construction industry for all steel hollow sections used in any building construction. AS/NZS 1163 steel pipe has some unique testing requirements, such as the direction of cutting test pieces for tensile and impact

ERW MS tube is made by applying resistive heat energy at both ends, which melts the edges of the steel plates and combines them into a single piece, this type of ms pipe produces a tasting weld. Advantage: It has the advantages of low manufacturing cost, high production efficiency and smooth surface. Moreover, for the size

Black steel pipes are usually made of carbon steel or alloy steel, which have extremely high mechanical strength and anti-corrosion properties. How to blacken steel? With black paint for steel on the surface, the object presents a deep black tone, leaving the viewer with a calm and atmospheric feeling. Compared with conventional metal pipes, the durability
