橡胶接头是用于金属管道之间起挠性连接作用的中空橡胶制品。 Introduction: Rubber joints are hollow rubber products used for flexible connection between metal pipes. It consists of inner and outer layers of rubber, ply and traveller, which form a tubular rubber piece. After vulcanization, it is combined with metal flange or parallel joint loose sleeve.
are hollow rubber products used for flexible connection between metal pipes. It consists of inner and outer layers of rubber, ply and traveller, which form a tubular rubber piece. After vulcanization, it is combined with metal flange or parallel joint loose sleeve. Not only can it reduce vibration and noise, but it can also compensate for thermal expansion and contraction caused by temperature changes. It is widely used in various pipe systems.
Cast iron flanges are an important type of matching flanges for rubber joints. Generally there are two types of carbon steel forged flanges and cast iron flanges. Carbon steel forged flanges are generally galvanized and the price is relatively high. But durable. Cast steel flanges are generally lower in price and not as strong as forged flanges. They are generally spray-treated, also known as Shanghai standard flanges.
The difference in the price of various flanges, the flanges sold on the market, the cheapest casting, followed by casting and forging, the price of pure forging is higher. This means that you can come to a general conclusion after comparing the price of each rubber joint. Cut the flange in half, the cast flange has trachoma, and the pure forged flange does not have trachoma. Forged flanges are sometimes found with cracks. Generally, the negative dimensions of cast flanges on the market are 1-5mm, the edges are chamfered irregularly, and the edge burrs are not smooth. Because cheap work is not so fine. Forged flanges have small or positive tolerances. The distinction between cast steel flanges and cast iron flanges: The toughness of cast iron flanges is poor, and can usually be cracked with a hammer. The material of the flange can generally be close to the low carbon, or it will easily crack if it is not welded.
