Six factors should be considered when selecting valve sealing surface materials

The sealing surface is the most critical part of the valve. The quality of the sealing surface directly affects the service life of the valve. The material of the sealing surface is an important factor to ensure the quality of the sealing surface. Therefore, the following factors should be considered when selecting the valve sealing surface material: ①Corrosion resistance. “Corrosion” refers to the process in which the sealing surface is damaged by the medium. If the surface is damaged in this way, the sealing performance cannot be guaranteed.Therefore, the sealing surface material must be corrosion resistant. ②Anti-abrasion. “Scratch” refers to the damage caused by friction of the material during the relative movement of the sealing surface. This kind of damage will inevitably cause damage to the sealing surface. Therefore, the sealing surface material must have good scratch resistance, especially for gate valves. ③Erosion resistant. “Erosion” refers to the process of destroying the sealing surface when the medium flows through the sealing surface at high speed. This kind of damage is more obvious in the throttle valve and safety valve used in the high temperature and high pressure steam medium, which has a great impact on the...

What is the Basket Strainer?

Basket strainer can filter impurities from the fluid, and the filtration area is larger than the diameter pipe area about twice or triple, which is also larger than Y and T strainer. The shape of the filter looks like a basket, so it is called basket strainer. ♦ Working temperature: -80℃-+450℃ ♦ Nominal pressure: PN10-PN50 ♦ Shell material: carbon steel, stainless steel (SUS304, SUS304L, SUS316, SUS316L), PTFE LITED. ♦ Filter material: stainless steel. ♦ Sealing ring material: oil-resistant asbestos rubber, metallic spiral wound gasket, PTFE. ♦ Working temperature: carbon steel: -40~380℃ stainless steel: -80~450℃. ♦ Connection type: flange connection, female thread, welding. ♦ Flange standards: GB, JB, ANSI, JIS and other standards. Applicable working condition: a. Weakly corrosive materials in chemical and petrochemical production, such as water, ammonia, oil, hydrocarbons, etc.; b. Corrosive materials produced in chemical industry, such as caustic soda, soda ash, concentrated and dilute sulfuric acid, carbonic acid, acetic acid, ester acid, etc.; c. Low-temperature materials in refrigeration, such as: liquid methane, liquid ammonia, liquid...

Rubber Flexible Joint

Introduction The rubber joint is a special joint used to connect pipes. Its main function is to compensate for the thermal expansion and contraction of the pipes, vibration absorption, and pipe misalignment. Rubber joints are made of rubber, have good elasticity and corrosion resistance, and are widely used in industrial piping systems. Performance characteristics: 1. Small size, light weight, good elasticity, easy installation and maintenance. 2. It can produce lateral, axial, and angular displacement during installation, and is not restricted by pipes that are not through the center and flanges that are not parallel. 3. Rubber joints can reduce the noise transmitted by the structure during operation and have strong vibration absorption capabilities. Picture:

What is Y Strainer?

Introduction The “Y strainer” is a mechanical filtration device used in piping systems to remove solid particles from flowing liquids or gases. Y type Strainer is an indispensable device in the piping system for conveying medium. The Y strainer is typically installed in pipelines to protect downstream equipment like pumps, valves, and meters. It also can be used alone for cold and hot circulating water system, compressed air, steam, oil and other media pipelines. It is used to remove impurities in the medium to protect the normal use of valves and equipment. Picture: Suitable medium: Body Suitable medium Cast iron, Ductile Iron Used in drainage systems of industries, mines, high-rise buildings, power stations, etc. The medium in most working conditions is water Carbon steel Used to remove various impurities in hot water, cold water, steam and compressed air. In particular, this product needs to be installed in front of the circulating water pump in the boiler room to protect the equipment and pipes from blockage and wear. It is also suitable for pipelines of various steam equipment. Stainless...

Wafer Check Valve Introduction

Wafer Check Valve/Butterfly Check Valve Product Introduction Wafer check valve is mainly used at the water supply and drainage pipe network wells or the water pump outlet of fire fighting, petrochemical, light textile, papermaking and high-rise buildings. It is a safety device to prevent the backflow pressure difference of pipeline medium and forming water hammer impact and water pump reversal when the water pump is stopped. Applicable Medium Clear water, neutral liquid, Oils, etc. Application field Municipal construction, water treatment, water supply and drainage, water conservancy projects, etc. Product Advantages 1) Small size, light weight, compact structure and convenient maintenance; 2) The valve plate is of dual type, which can close quickly under the elastic moment of the spring; 3) Due to the fast closing effect, it can prevent the medium from backflowing , and eliminate the strong effect of water hammer; 4) The valve body structure has small length, good rigidity, safety and reliability; 5) Surface coating: Epoxy powder coating is adopted, with strong adhesion and good weather resistance. It can be used indoors and outdoors; 6) The numerically-controlled machine tool grinds the sealing surface of the body, with good flatness and surface roughness, which can ensure the...
