Welcome to Shandong Xunwei International Trade Co., Ltd.

Welded pipe is also called welded steel pipe, it is made of steel strip cut into narrow strip, and then with a mold cold processing crimped into a tube. A high frequency submerged arc welder then welds a seam of pipe. Because of the different welding process, it is divided into resistance welding pipe and automatic arc welding pipe. And because of the different welding forms, it is divided into straight seam welding pipe and spiral welding pipe.

Straight seam welding pipe production process is simple, high production efficiency, low cost and has rapid development. Welded steel pipe is often used to transport fluid and powdery solids, exchange heat energy. In addition to, it is also a kind of economic steel. Using steel tubes to manufacture building structures, such as grids, supports and mechanical supports, can reduce weight, save metal by 20-40% and increase construction speed.

Introduction to Custom-Shaped Steel Plate Components

★ ★ ★ ★ ★

Custom-shaped steel plate components are non-standard, irregularly geometric metal parts made from steel plates through processes such as laser cutting, stamping, bending, welding, and precision machining. Their core feature lies in "customization on demand"—they can be accurately adapted to the structural requirements, installation space, and functional needs of specific equipment. These components are widely used in fields including machinery manufacturing, construction machinery, automotive, shipbuilding, and steel structure construction.

Introduction to Construction Machinery Attachments

★ ★ ★ ★ ★

Construction machinery attachments are key accessories installed on the main body of construction machinery. They are designed to enhance the main machine's functions and expand its operation scope. With a wide variety of types and strong targeting, these attachments can be adapted to different main machines and operating scenarios

Introduction to Construction Machinery

★ ★ ★ ★ ★

In the field of construction machinery, excavators and loaders are core equipment with complementary functions and high-frequency applications in earthwork operations, widely serving key areas such as construction, transportation, mining, water conservancy engineering, and urban municipal renovation. Together, they form a "golden partner" for site cleaning in the early stage of engineering, material handling in the middle stage, and basic operations in the later stage.

Introduction to Agricultural Machinery

★ ★ ★ ★ ★

Through the application of mechanization and intelligent technology, equipment has significantly replaced human labor, not only significantly improving agricultural production efficiency and reducing farmers' labor intensity, but also achieving scientific planting methods such as precise fertilization and irrigation, effectively saving resources, reducing agricultural non-point source pollution, and ensuring stable agricultural product yield and quality. It is a key force in promoting the transformation of traditional agriculture towards scale, intensification, and modernization.
