45° Graphite packing ring, self-lubricating talc ink ring

Self sealing 45 ° graphite packing ring and self-lubricating talc ink ringAccording to their purposes, they are mainly divided into two categories: one is used as sealing packing on various pumps, valves, and reaction vessels; Another type is graphite gaskets used on various pipeline flanges.
① Sealing packing
Graphite packing ring sealing packing is a pre formed packing material that is directly formed on a press machine by winding expanded graphite strips cut into appropriate width and length into metal molds of different specifications. It is suitable for various globe valves, gate valves, regulating valves, ball valves, and valves.
② Sealing gasket
It can usually be divided into two types. One is pure graphite gasket, which is formed by pressing expanded graphite granules directly in a metal mold, or it can be directly punched or cut from expanded graphite sheet; Another type is graphite winding pad, which is made by overlapping metal strips and expanded graphite and can be used under higher pressure.

Flexible graphite sealing ring manufacturer
Using flexible graphite tape or flexible graphite to weave fillers, molded into circular products of different sizes.
Graphite rings are made of graphite strips or woven graphite roots, which are molded into rings of different sizes. This type of ring has good resilience, chemical stability, and can provide effective sealing. Easy to use and install, it can also interact with other carbonyl rings. Even under harsh conditions, graphite rings are very stable and reliable.
Suitable for media such as hot water, high temperature, high pressure steam, heat exchange liquids, nitrogen, organic solvents, hydrocarbons, low-temperature liquids, etc. Used for compressors, pumps, valves, chemical instruments, meters, etc. Pressure (Mpa): 25 Temperature (℃): -200~850 Linear velocity (m/s): 30 PH value: 0~14 Graphite rings are divided into flexible graphite and carbon graphite rings. Carbon graphite rings are mainly used for sealing mechanical rotating parts. Carbon graphite rings have the characteristics of high temperature resistance, corrosion resistance, and wear resistance
Flexible graphite packing ring: The molded graphite packing ring is made by winding and molding low sulfur expanded graphite tape, with precise dimensions, adjustable density, and no external fillers or adhesives. Generally, the cross-section is square, but it can also be wedge-shaped in a V-shape, with the latter two being suitable for high-voltage parts.

Graphite rings are divided into flexible graphite and carbon graphite rings.

Carbon graphite rings are mainly used for sealing mechanical rotating parts.

Carbon graphite rings have the characteristics of high temperature resistance, corrosion resistance, and wear resistance.

Performance and characteristics of graphite rings:
1. Graphite rings have good self-lubricating properties
2. High rebound coefficient of graphite ring
3. Graphite rings can be cut at a 45 ° angle according to user needs

4. On a small rotating table, invert and rotate the upper ring of the crystallizer, and heat the crystallizer with liquefied petroleum gas until the graphite ring falls off.

5. Place the upper ring of the crystallizer and install a new graphite ring, paying attention to adding small amounts of material to press the graphite ring. Apply lard once when the graphite ring is hot.

6. After natural cooling, replace all materials and clean thoroughly, paying attention to the small O-ring and its position, and aligning the overflow hole.

Langfang Saio Sealing Wholesale Graphite Packing is mainly made of various reinforced fibers, metal wires (steel wire, copper wire, nickel wire, carbon fiber, pre oxidized wire, glass yarn) and other reinforced graphite wires woven with precision as raw materials. Suitable for dynamic sealing under high temperature and high pressure conditions. Except for a few strong oxidants, it can be used to seal media such as hot water, superheated steam, heat transfer fluids, ammonia solutions, hydrocarbons, and low-temperature liquids. It is mainly used for sealing valves, pumps, and reaction vessels in high-temperature, high-pressure, and corrosion-resistant media. It is also a versatile sealing product.

The Saio graphite packing seal is filled with packing inside the packing box, and the graphite packing is pressed onto the surface of the shaft through a packing gland. Due to the rough surface of the shaft, it can only partially adhere to the graphite packing, while some do not, forming countless mazes. When the pressurized medium passes through the shaft surface, the medium is throttled multiple times, achieving sealing through this' maze effect '

The adhesion and friction between the Saio graphite packing and the shaft surface are similar to sliding bearings, and there should be sufficient liquid for lubrication to ensure a certain lifespan of the seal, known as the "bearing effect". Therefore, good packing sealing is a combination of labyrinth effect and bearing effect

The clamping force of the Saio graphite packing on the shaft is generated by tightening the gland bolts. Due to the fact that the filler is an elastoplastic material, when subjected to axial compression, frictional forces are generated, causing the compression force to gradually decrease along the axial direction. At the same time, the radial compression force generated makes the filler tightly adhere to the shaft surface, preventing the medium from leaking out. The distribution of radial compression force decreases sharply from the outer end (cover) to the inner end, and then becomes gentle. The distribution of medium pressure gradually decreases from the inner end to the outer end. When the medium pressure at the outer end is zero, there is little leakage, and when it is greater than zero, there is leakage

Saio graphite packing has good self-lubricating properties, low friction coefficient, wear resistance, and temperature resistance. After friction heating, it can withstand a certain temperature, is easy to disassemble, simple to manufacture, and has a low price. Graphite disc root is a flexible and high-strength woven disc root made of graphite wire reinforced with stainless steel wire. The excellent sealing performance achieved when combined with other packing materials makes it a sealing material, especially under high pressure. Except for a few strong oxidants, it can be used for sealing hot water, high-temperature and high-pressure water vapor, heat transfer fluids, hydrogen gas, ammonia, organic solvents, hydrocarbons, low-temperature liquids and other media. It is also a universal sealing gasket.
