Polyethylene thermal insulation steel pipe is a type of lightweight, high-strength, and corrosion-resistant non-metallic pipe. It’s manufactured by winding fiberglass with a resin matrix onto a rotating mandrel layer by layer, following specific process requirements. Between these layers of fiberglass, a sand layer is evenly distributed to enhance structural integrity. This design ensures optimal material utilization while maintaining both rigidity and stability. Compared to traditional steel pipes, this pipe offers superior chemical resistance, lighter weight, higher strength, no scaling issues, better shock absorption, longer lifespan, lower overall costs, and quicker installation—making it highly reliable and widely favored by users.
The performance features of high-density polyethylene thermal insulation steel pipe are remarkable:
1. **Superior Thermal Insulation:** Utilizing rigid polyurethane with low thermal conductivity as the insulation material ensures excellent heat retention capabilities.
2. **Minimal Temperature Loss:** During regular operations, when transporting water at 130°C over a distance of 40 kilometers, the temperature drop remains negligible at approximately 1°C.
3. **Waterproof & Corrosion Resistant:** Equipped with robust waterproofing and corrosion resistance, these pipes eliminate the need for additional trenching. They can be directly buried underground or submerged in water, simplifying construction processes and reducing total expenses.
4. **Low-Temperature Durability:** Even under frigid conditions, they maintain their corrosion resistance and impact tolerance, allowing direct burial within permafrost layers.
5. **Corrosion-Resistant Outer Shell:** Featuring an HDPE (high-density polyethylene) outer casing, these pipes are immune to biological and chemical corrosions.
6. **Customizable Sizes:** Available in various diameters ranging from DN20 to DN1200, along with matching fittings like elbows, tees, reducers, and fixed joints, tailored to meet individual customer demands.
7. **Industry Standard Compliance:** Adheres strictly to urban construction industry standards.
8. **Surface Preparation Excellence:** Before foam application, the outer steel pipe undergoes sandblasting treatment, while the inner plastic pipe receives corona treatment. These steps ensure that the surface tension of the outer shell pipe reaches 50 dynes/cm, meeting stringent quality criteria.
9. **High-Quality Raw Materials:** Made from high-density polyethylene, these pipes incorporate antioxidants and other additives to guarantee top-notch raw material and finished product quality. All products conform to the CJ/114-2000 standard and surpass direct outer protective pipe requirements for buried pipelines, elevating overall product quality.
10. **Advanced Manufacturing Equipment:** With state-of-the-art equipment including imported and domestic high-pressure foaming machines and hydraulic threading machines, we consistently deliver premium-quality products.
In conclusion, the high-density polyethylene thermal insulation steel pipe stands out as an innovative solution offering unparalleled durability, efficiency, and cost-effectiveness across multiple applications. Whether you're looking to optimize energy savings or reduce maintenance costs, this pipe provides unmatched advantages.
Flexible Gate
Flexible lift gate is a flexibel soft curtain door, inside and outside the two curtains , curtains used between the aluminum beams connected with a vertically movable rail , the roof beams have levels not in the same straight line and hanger large plants in particular Be applicable , Flexible lift door installation does not take up interior space in the hole inside , When the first move to open the door , and finally superimposed over the hole , Off event curtain rail first and then fall down until its is completely closed
Door body composition :
The bottom of the door curtain rail aluminum beam beam seal top drive system and transmission of electrical control systems and safety devices
Flexible door features:
1. Light weight compared with other types of the same size door , flexible door lighter weight reduces the strength of steel at the top of the doorway architecture degree requirements ,
2. Small compared with the same specification of the machine style doors 2, footprint ,flexible installation in the door after the hole is turned on internally stacked above the hole , do not take up interior space , Large Span hole may be provided a plurality of movable rail the entire door into several independent stacking doors shorten the span of a single door so that the overall thickness of the door is reduced , further reducing the footprint
3. Rational layout flexible doors with movable rail rail can set different activities based on the specific circumstances of the door into the door several sizes of uneven accumulation of doors to make the building as a whole rational layout greatly reduces the overall architecture of the space and cost
4. The wind strength between two layers of high flexible door curtain as the bottom of an aluminum beam has a wind skeleton steel structure , By adjusting the beam thickness and spacing , which can resist wind pressure of any intensity , so the door can be flexible for use in any area
5. The tensile strength of the flexible door after door curtain is double polyester fabric , high tensile wire rope equipped with ultra-high hole suitable for large machinery such as aircraft hangars and repository
6. The curtain coated with vinyl coated with a waterproof sunscreen and smoldering performance , capable of sound absorption retardant insulation mildew proof and so on
7. Safe door , Cube with anti-lock break to ensure safety in case of accidental breakage of wire rope jammed in the door quickly experience anywhere rails , Multiple protection features mechanical and electrical installation to ensure t he safety of goods passing aircraft and other vehicles and personnel , the movable rail is also equipped with anti-fall device , you can ensure reliable parked at the top of the hole after the movable rail is raised without falling , The bottom of the door is equipped with and airbag , it will immediately rebound to rise until the safety door drops open when obstacles encountered in the process , You can also install infrared protection device on the door
