carbon vs silicon carbide mechanical seal made in china

You must consider the “environment” the seal will be exposed to when selecting the design, and importantly, the material of your mechanical seal. The saying “pay me now, or pay me later” very much applies to seals as not selecting the right material will cost more in the long run.

For all environments the material used for the seal face must be stable, be able to conduct heat, be chemically resistant and deliver good wear resistance. However, certain environments will need these properties to be stronger than in others.

Abrasive and harsh environments mean that the material selected must be able to withstand this, which can be more expensive. However the cost will be returned to you over time as poor material grade selection will only result in costly shut downs, repairs, refurbishments or replacements of the seals once again.

Various materials can be used for seals depending on the requirements and environment they will be used for. By looking at material properties such as hardness, stiffness, thermal expansion, wear and chemical resistance, you are able to find the ideal material for your seal.

When mechanical seals first arrived, seal faces were often made from metals such as hardened steels, copper and bronze. Over the years, more exotic materials have been utilised for their property advantages, including ceramics and various grades of mechanical carbons.

The mechanical seal ring or face is the axially flexible member of the end-face mechanical seal. The design of the mechanical seal ring must allow for minimizing distortion & maximizing heat transfer considering the secondary sealing element, drive mechanism, spring and ease of assembly.The mechanical seal ring/face always contains the diameter balance.The shape of the seal rings/faces may vary considerably according to the incorporation of various design features. In fact, the shape of the mechanical seal rings/faces is often the most distinct identifying characteristic of mechanical seals.The mechanical seal faces/rings are mainly made of pressureless sintered silicon carbide/alpha silicon carbide/alpha sic/ssic, silicon carbide/sic,ceramic 99.5%,ceramic 99%,ceramic 95%,tungsten carbide/TC,carbon graphite and sometimes the mechanical seal faces/rings are chrome coating of the stainless steel.

Mechanical seals are necessary for many industries. Finding a reliable mechanical seal manufacturer can be difficult. In this blog post, we will discuss the features of a good mechanical seal manufacturer.

A mechanical seal is a type of metal or plastic closure that can be used to ensure the integrity of an assembly. Mechanical seals are typically made from a variety of materials, such as silicon carbide, carbon graphite, aluminum oxide, and stainless steel, and can be designed for a variety of applications.

The key qualities that make a good mechanical seal are quality control, product consistency, and reliability. To ensure quality control, manufacturers typically have rigorous testing procedures in place to test the durability and performance of their products. Product consistency is key to ensuring that the seals installed in an assembly are uniform and fit properly. Reliability is essential for ensuring that the seals remain in place during use and do not fail catastrophically.

Mediums: week acid, week alkali, grease, liquefied hydrocarbon, room temperature vitriol, hydrofluoric acid, and sodium hydroxide (bellow the boiling point). This material is wear proof.

SSIC Silicon carbide mechanical seal is a kind of silicon carbide product produced with silicon carbide material. Silicon carbide mechanical seal has heat resistance, according to different process, the performance of heat resistance is not the same. The reaction-sintered silicon carbide seal ring can be used at 1300, while the pressure-free sintered silicon carbide seal ring can reach 1600.

Ssic mechanical seal is the most versatile friction material in mechanical seals.It has strong chemical resistance performance, high mechanical strength, good wear resistance, high temperature resistance, good self-lubrication, light weight, low coefficient of thermal expansion, high hardness, good dimension at extremely high temperatures , strong corrosion resistance and high elastic modulus, long service life and other characteristics.Applicable to the production of various mechanical rings,bearings,bushings and other friction materials.Sic mechanical seal are widely used in petroleum,electric power,light industry,aerospace,automotive,paper and sewage treatment,chemical pump and its rotary machinery and other fields,and paired with carbon graphite,sic mechanical seal has the smallest friction coefficient. It can be used as a high-parameter mechanical seal.

Materials used for the manufacture of mechanical seal faces. These materials must meet the tribological demands unique to mechanical seals. Industry has evolved primarily to the use of mechanical carbons and ceramics for these components. A mechanical seal (Fig. 1) is by its very nature a collection of components that are designed to control leakage of a fluid through a sealing interface. These components serve a wide variety of functions and correspondingly require a wide range of material properties. Many of these properties, such as mechanical strength, thermal conductivity, or corrosion resistance, are similar to considerations made for many other devices. Some properties, however, are unique to mechanical seals, such as coefficient of...
