Large Diameter Welded Steel Pipes are used to transport fluids or gases over long distances. These are commonly used in the oil and gas industries. Stainless large-diameter pipes are also used in a variety of structural applications. That includes oil rigs, ships, pressure vessels, and machinery parts. Several factors need to be considered before purchasing a large-diameter pipe. Stainless steel is a very versatile material. It can be forged into various shapes and is oxidation-resistant. Because of its durability, it is often used for piping. Many industrial sectors use it for various applications, including the petroleum, food, and chemical industries. In addition, it's a relatively low-maintenance metal.

Large Diameter Pipes are designed to carry more fluids or gases at a given flow rate, which is a significant advantage. For example, they can carry oil, fuel, or other liquids from a refinery to a tank farm. Using this kind of pipe can also help prevent abrasion damage. Moreover, it can help keep the pressure down. Since the diameter of these pipes is significant, they can withstand intense weather conditions. While selecting a large-diameter stainless pipe, selecting a grade with the strength and corrosion-resistance properties required for the application is essential. If the application involves high pressures, it is better to choose a grade that has higher strength. Alternatively, a grade that has a high wall thickness can also be selected. A high wall thickness can reduce the amount of traffic passing through the system.

This high-frequency plasma welding unit of Jiangyin Longyu has the characteristics of energy concentration, high productivity, fast welding speed, small stress and deformation, stable electric arc, and is suitable for welding thin plate and box material. Therefore, this unit can weld through 5mm-50mm thick plates. And has a good efficiency. This high-frequency plasma arc welding is specially used for welding pipe ring joints, with high efficiency and beautiful appearance.

Large stainless steel winding unit

Jiangyin Longyu Stainless Steel Welding Pipe Co., Ltd. equipment introduction. Large stainless steel rolling machine, commonly known as press. This unit can be rolled up to a maximum thickness of 50mm and each section can be up to 3.2m in length.

Therefore, for some 9-12 meter long pipes, we can divide a 9-12 meter pipe into 3-4 sections for ring seam welding through this equipment. Because the thickness of the circle can reach 50mm, the length may be slightly limited.

6000 tons of oil press flanging machine

The whole machine adopts a steel plate welding structure, eliminating internal stress when using vibration, the machine has high strength and good rigidity; Hydraulic double cylinder (using Japanese seals) upper transmission, mechanical block, torsion shaft synchronization, reliable movement balance, high precision;

The rear stop distance and slide stroke adopt electric adjustment and manual fine adjustment, and are equipped with a digital display device, easy to use; The upper die is equipped with a deflection compensation device. Bending machine mold selection of high-quality materials for processing, bending machine manufacturers have good wear resistance after heat treatment, and can be customized according to customer requirements, to provide specific molds (select configuration). Moreover, our equipment is a 6,000-ton press, which can be heated to fold edges, so the maximum folding thickness is 120mm, and the length can be 5 meters.

Q1: Are you a trading company or manufacturer?

We are a processing type company specializing in processing stainless steel for 304/304L large diameter thick wall stainless steel welded pipe and other materials. Prompt delivery, low price, high quality, unique insight into various materials of stainless steel, rolled round, straight seam, ring seam.

Q2: What are the company's main products?
