The prefabricated components of a piping system are called spools. The spools consist of three components: الأنابيب, الشفاه, والتجهيزات. The spools are assembled during fabrication and shipped pre-assembled to facilitate assembly with jacks, gauges, and other joining equipment. باختصار, the spools join long lengths of pipe with flanges at the ends and must be properly positioned to withstand the weight and force of the structure. كبات أنابيب مسبق

The prefabricated coils are primarily made of stainless steel. Their good adhesion to steel provides superior long-term corrosion resistance and pipeline protection in a low-temperature environment. Higher adhesion properties ensure excellent cathodic dissolution resistance, which reduces the overall cost of cathodic protection during pipeline operation.

Shipbuilding and maintenance encompasses a wide range of projects and involves intensive piping to connect a variety of equipment and transport fluids and gases. Prefabricated pipe spools play an important role here. كبات أنابيب مسبق

ج&ن is a professional supplier. We have the ability to provide prefabricated pipe spires, including pipes, التجهيزات, and flanges, based on design drawings and requirements, and prefabricate them into “spires” suitable for on-site assembly. كبات أنابيب مسبق

Features of Prefabricated Pipe Spools

• Welding method: Plasma welding
• تقتيش: PT or RT& Pressure Test
• Custom made as per provided drawings

Pre-Fabrication Process

1. هندسة & تصميم

 Detailedisometric drawings, ص&بطاقة تعريف, and 3D models are created
Selection ofمواد, pipe sizes, والتجهيزات
Weld mapping andnon-destructive testing (NDT) planning

2. Material Procurement & Cutting

الأنابيب والتجهيزات ,flanges are made according to project specifications
Precisioncutting using CNC machines, saws, and plasma cutting

3. اللحام & Assembly

Butt welding, لحام المقبس, and TIG/MIG welding for strong joints
الشفاه, المرفقين, المحملات, and valves are fitted as per design
Welding inspected usingX-ray, ultrasonic, or dye penetration testing

4. المعالجة السطحية & طلاء

Galvanization, تلوين, or powder coating for corrosion resistance
Internal lining (إف بي إي, epoxy, rubber, or FRP) based on application

5,الاختبار & ضبط الجودة

Hydrostatic pressure testing ensures leak-proof operation
Dimensional and alignment checks for precision
NDT (التصوير الشعاعي, يوت, MPI) to detect welding defects

6. Packaging & مواصلات

Pipe spools are labeled, bundled, وshipped to the installation site
Modular skid units can be transported for quick assembly

Advantages of pipe spools prefabrication:

Parts are designed as “components” و “sub-components” before they are needed, so they can be installed on demand instead of being manufactured on site. It is convenient for the coordination and control of quality, schedule and management in a fixed area, reduces the workload of on-site prefabrication and on-site installation, and greatly improves the installation, quality and schedule of the whole project. And craftsmen are less exposed to the more adverse working environment of a construction site, improving safety performance.
