Black industrial pipe fittings are made by adding black masterbatch (masterbatch) during the production process, in order to reduce the light transmittance of the pipe, improve the anti-aging and anti-ultraviolet performance of the pipe fittings, and thus extend the service life of the pipe fittings. This practice not only increases the service life of the pipe but also enhances its durability, allowing Black industrial pipe fittings to maintain good performance in various industrial environments.
Why produce Black industrial pipe fittings?
Black industrial pipe fittings are produced by adding black masterbatch (masterbatch) to reduce the light transmittance of the pipe, improve the anti-aging and anti-ultraviolet performance of the pipe, and thus extend the service life of the pipe fittings.
Some people may ask: Why not make it transparent? In this way, where is the blockage, can’t it be seen at a glance?
Because some pipes are installed in an open-air environment and have to experience wind and sun, the light transmittance of transparent pipes will be very strong. If it is too strong, the sunlight will directly shine on the pipe wall, and algae, moss, and other substances will be produced on the inner wall of the pipe, which will cause secondary pollution of the water quality.
Adding masterbatch can improve the light-shielding performance of the pipeline, delay pipeline aging, and increase the service life of the pipeline. Therefore, the state stipulates that masterbatch must be added to the production of pipelines.
Material category
The materials commonly used for Black industrial pipe fittings are mainly PVC, HDPE, PP, etc.
1. PVC (polyvinyl chloride) is a commonly used plastic material with good chemical stability, corrosion resistance, and low cost. PVC pipe fittings are widely used in water supply and drainage systems, chemical fluid transmission, and other fields, and are favored for their excellent corrosion resistance and durability.
2. HDPE (high-density polyethylene) is a corrosion-resistant, wear-resistant, and low-temperature-resistant plastic material with good mechanical properties and chemical stability. HDPE pipe fittings are suitable for various industrial fluid transmissions, especially in occasions that require high-pressure resistance and corrosion resistance.
3. Polypropylene (PP): PP is a plastic with the lowest density, usually a translucent colorless solid, odorless and non-toxic. PP pipe fittings are suitable for the manufacture of various industrial piping systems, including food-grade applications, due to their excellent heat resistance and corrosion resistance, and their non-toxic and harmless characteristics ensure safe use.
These pipe fittings made of these materials are suitable for different industrial application scenarios due to their respective characteristics, from water supply and drainage to chemical fluid transmission, from indoor wiring to outdoor industrial pipelines, and have a wide range of applications. Choosing the right material depends on the specific use environment and needs.
What is the difference between black industrial pipe fittings and white ones?
Purpose and use environment:
Black industrial pipe fittings are usually used in open-air environments because black masterbatch (masterbatch) is added during the production process, which helps prevent ultraviolet rays from damaging the molecular chain of polyethylene, thereby extending the service life of pipes and fittings and making them more resistant to aging and UV exposure. This treatment is mainly aimed at outdoor or UV-prone environments to protect pipes from aging.
White industrial pipe fittings are mainly used in deeply buried occasions because these occasions will not be directly exposed to ultraviolet rays and have lower color requirements, so there is no need to add masterbatch to change the color, maintaining the white color of the raw materials.
Material essence:
Whether it is black or white industrial pipe fittings, their basic materials and structures are the same. Black pipe fittings become black because of the addition of black masterbatch, but this does not affect their quality and performance. White pipe fittings maintain the color of the raw materials, and there is no difference between the two in essence.
