Located in the central areas of Beijing, Tianjin, and Shijiazhuang, the company covers an area of 28500 square meters and has strong technical strength, excellent technical equipment, and talents. Our company mainly produces polyurethane products, rock wool products, fiberglass wrapped pipes, polyethylene, etc. Our company can customize various shaped products according to customer requirements, achieve scientific design, reasonable construction, and ensure that the quality of the products meets customer needs. Over the past few years, the company has established its own brand, Xinda, through excellent products, thoughtful services, and honest behavior, and has become a major player in the construction of many projects in China. At that time, we welcome calls and visits from manufacturers from all over the world to discuss business. Enterprise goals: Quality, the foundation of business, management, and the path to strong business; Efficiency is the source of prosperity. Driven by technology and striving for survival through quality. Seek efficiency from quality. Benefit comes from the return of serving society. Enterprise tenet: Quality comes before production, customer first, providing customers with excellent products and thoughtful services. Our commitment: The market is changing, but our commitment remains unchanged. The company adheres to the principle of "excellent quality, reputation first" to serve society and benefit humanity. Our company mainly produces polyurethane composites, foam insulation boards, foam insulation pipes, rock wool products, FRP winding pipes, and high-density polyethylene black and yellow jacket pipes (i.e., thermal insulation outer protective layer); Prefabricated polyurethane direct buried insulation pipe (i.e. pipe foam insulation); Prefabricated insulation elbow; Prefabricated insulation pipe fittings; Waiting for insulation materials. Our company can customize various shaped products according to customer requirements. And undertake polyurethane foam insulation projects for various large, medium, and small pipelines such as steam pipes, plumbing pipes, air conditioning pipes, power pipes, HVAC pipes, etc.

　　Characteristics of Directly Buried Prefabricated Steel Jacketed Steel Insulated Pipeline:

　　1. Reduce project costs.

　　2. Low heat loss and energy-saving.

　　3. Good corrosion resistance, good insulation performance, and long service life.

　　4. Less land, faster construction, conducive to environmental protection.

　　5. Safe.

　　According to the design and user requirements, the three-layer insulation structure of directly buried prefabricated steel sleeve steel insulated pipelines generally uses GB816387 seamless steel pipes (GB971188; SY/T503892) and straight seam pipes (GB309293). After advanced shot blasting treatment, the rust removal grade of the steel pipe surface reaches SA2 level in GB8923-1988 standard, and the surface roughness reaches r=12.5 μ m in GB6060.5-88 standard.

　　Second layer: Polyurethane insulation layer

　　A high-pressure foaming machine is used to inject rigid polyurethane foam into the cavity formed between the outer protective layers of steel pipes Commonly known as "pipe foaming method". Its function is waterproof, followed by insulation, and the third is to support the weight of the heating network. When the temperature of the conveying medium is -50 ℃ -120 ℃, rigid polyurethane foam is selected as the insulation layer.

　　Third layer: high-density polyethylene protective layer
