NXF UNS N10276 2.4819/NiMo16Cr15W/C276 OD DN15-1200 Class 3000-9000 Nickel Alloy Forging Technology Socket Welding Union

Socket-welded joint of forged components

1.Core definitionBy inserting the steel pipe into the socket hole of the joint and using welding techniques (such as arc welding, gas welding) to fuse the steel pipe with the joint, an integrated sealing structure is formed, achieving the connection of the pipeline.

2.Core featureHigh-pressure adaptability: Capable of withstanding pressure levels of 3000LB, 6000LB, and even 9000LB. Suitable for pipelines transporting high-temperature, flammable, explosive, and toxic media (such as main transportation pipelines in petrochemical industries and nuclear power cooling systems).Sealing reliability: After welding, the steel pipe and the joint form a seamless integration, eliminating the risk of leakage, and featuring excellent vibration and impact resistance.Construction requirements: Requires a professional welding team to operate. The construction period is long. Once the welding is completed, disassembly and maintenance are extremely difficult.

1. Material selection: Choose appropriate materials, such as steel, stainless steel, and aluminum alloy, based on specific requirements. Select the hardness, corrosion resistance, and other properties of the materials.

2. Blank forming: The pipe fittings are mainly formed by pressing and forging round steel or steel ingots into blanks.

3. Machining: The blanks are machined using a lathe, including designing the parameters of the threaded joints, selecting appropriate machining tools and materials, and performing pre-processing (coarse and fine machining) steps. During the coarse machining stage, a thread milling machine or thread broaching machine is used for initial processing; in the fine machining stage, a precision lathe is used for meticulous processing to ensure the accuracy and surface quality of the joints.

4. Post-processing techniques: After processing, post-processing techniques such as deburring, grinding, and surface treatment are carried out to improve the durability and appearance of the joints

.5. Quality review: Measure and inspect the dimensions, shapes, and surface quality of the threads to ensure that the joints meet the design requirements.

6. Assembly and inspection: Perform the assembly and inspection of the threaded joints through a strict assembly and inspection process to ensure that each joint meets the high-quality and high-performance standards.
