Detailed description

Graphite packing

Seiko graphite as the main material compiled. With good self-lubricating and thermal conductivity, low coefficient of friction, versatility, flexibility, high strength, has a protective effect on the shaft and so on. Depending on the requirements, can be carbon fiber, copper, 304,316 L, Inconel alloy wire and other materials strengthened. Mainly used for high temperature and pressure conditions.

Q: What are the standards for sealing gaskets? Urgently, hope you sent me in the following or recommend this standard website to me, thank you.: Gasket standards are the following: to the left to the right, | gasket standard GB/T 4622.1 - 2003 GB/T 4622.2 - Classification of spiral wound gasket 2003 spiral wound gaskets for pipe flanges size GB/T 4622.3 - 1993 GB/T 9126 specifications of spiral wound gaskets for pipe flanges - 2003 non metallic flat gasket size GB/T 9128 - 2003 steel preparation of metallic ring gasket for pipe flange size GB/T 9129 - 2003 non metallic flat gaskets for pipe flanges technical conditions of GB/T 9130 - 1988 steel pipe flange connection metallic ring gasket for technical conditions of GB/T 13403 - 1992 large diameter carbon steel pipe flanges with a gasket GB/T 13404 - 1992 pipe flanges polytetrafluoroethylene envelope gaskets for GB/T 14180 - 1993 winding the type of gasket testing method of GB/T 15601 - 1995 pipe flanges with metal cladding gasket GB/T 19066.1 - 2003 flexible graphite corrugated metal gasket branch GB/T 19066.2 - 2003 flexible graphite metal gaskets for pipe flange gasket size GB/T 19066.3 - 2003 flexible graphite metal gaskets specification GB/T 19675.1 - 2005 pipe flanges with metal punching plate flexible graphite composite gasket size GB/T 19675.2 - 2005 pipe flanges with metal punching plate flexible graphite composite gasket technology JB/T 87 - 1994 pipe flanges for asbestos rubber gaskets for JB/T 88 - 1994 pipeline flanges with metal serrated gasket JB/T 89 - 1994 pipe flange metallic ring gasket for JB/T 90 - 1994 pipe flange Spiralwound gasket for JB/T 6628 - 1993 flexible graphite composite (plate) pad JB/T 8559 - 1997 JB/T 4718 - 1992 metal gasket pipe shell type heat exchanger with metal gasket JB/T 4719 - 1992 for shell and tube heat exchangers gasket

Q: Pictured above, the red circle is directly in the processing of A plane with PTFE gasket compression seal, but always leak, I think it is in the corner due to leakage when processing make fillet PTFE gasket is not very good and fit to face A. Now I want to processing into the structure shown below, put a circle at the corner where the processing tank, which can fit the PTFE gasket A good surface, but also not to experiment, did not know that it is okay, there is no expert advice!The main problems are as follows:First, is this the cause of the leak?Second, A surface in processing, roughness and flatness should be processed to how much more appropriate?Third, how about the tolerance of key dimensions?: 1, is a form of change, whether can use stainless steel plug screw with PTFE raw material belt canal seal.2, material selection, can choose bulk PTFE, can overcome the roughness of processing

Q: What is the basis for the classification of gaskets?: Look at what occasions, what environment, what media, what pressure, what temperature to develop a variety of different gaskets

Q: What tools or equipment do you have?Based on how iron does not hurt the spark plug on the seal pad downYou can cut the gasket, but you don't know what tools to use. Do you know?: You can use oil (preferably diesel), dip (pay attention to dip washers only), and then gently use a knife and other thin tools to pry.

Q: Figure 3 gear pump in the rubber seal gasket, draw the assembly plan, you need to draw the gasket out? How thick is the painting? The graph doesn't give it the relevant size.: Can be black, but the number should be marked in the material.

Q: What material is good for sealing gasket of steam pipe?: I'm not sure. Let's see what the filter medium is Then determine if the material is water, it is drinking water or water, compared with silica gel drinking water, living water, rubber line,

Q: Why is copper gasket always leaking out of the sealing surface?: The sealing surface of two different material substances in contact is generally cast iron, cast iron due to the thermal expansion coefficient of copper with different period of time when the heating operation of the equipment, will not leak in a short time, but when the device stops again after operation will be oil leakage.

Q: Where can I get the golf 7 taillight GASKET?: Hello, look at Taobao. [car has a problem, ask the car master. 4S shop professional technicians, 10 minutes to solve. ]

Q: Will the pipe flange be welded with graphite gaskets?: 1, pipe flange connection, welding flange, graphite gasket can not put in, otherwise it will burn graphite pad.2, the flange connection of the pipe, no matter what kind of material used in the gasket, are completed in the welding process after adding gaskets, to avoid welding when the high temperature of the arc burn gasket.3, welding fixed mouth flange, should be in the flange joint surface pad insulation object, prevent electric spark broken bad sealing surface. Only when the flange temperature drops below 60 degrees can the gasket be added, the fastening bolt is completed, and the connection procedure of the flange is completed.

Q: Good quality seals, which have, specializing in the production of rubber gaskets?: Hebei Qinghe Tianyu plastic products factory is a professional, they do the rubber seal (seal), manufacturers of large scale, long life, and has many large car manufacturers for many years, they have shown some online pad, other styles can be customized, contact with manufacturers and the Internet are very detailed.
