General overview
Grooved pipe fitting connection technology, also known as clamp connection technology, has become the current liquid, gas pipe connection technology, although the development of this technology in the domestic time later than foreign, but because of its advanced technology, is quickly accepted by the domestic market.From 1998 to now, after a few years of development and application, has gradually replaced the flange and welding of the two traditional pipe connection.Not only the technology is more mature, the market is generally recognized, and has been the positive guidance of national laws and regulations.
The application of grooved pipe fitting connection technology makes the complicated pipe connection process simple, fast and convenient.This is a big step forward in pipeline connection technology.
2.Brief introduction of grooved joint fittings
Groove connection pipe includes two categories of products: (1) the role of the connection sealing pipe has a rigid joint, flexible joint, mechanical tee and groove flange;(2) connect the transition role of pipe fittings have elbow, three, four, reducing pipe, blind plate and so on.
Advantages of grooved pipe fittings connection
Simple operation
The connection operation of grooved pipe fittings is very simple, without special professional skills, ordinary workers can operate after a simple training.This is because the product has incorporated a large amount of sophisticated technology into the finished product in a factory way.It only takes a few minutes to connect a piece of pipe, which simplifies the technical difficulty of field operation to the greatest extent, saves man-hours, and thus stabilizes the engineering quality and improves the work efficiency.This is also the general direction of the development of installation technology.
But the traditional welding and the flange connection pipeline connection way, not only needs the corresponding skill welding worker, moreover takes time, the worker's operation difficulty is big, and has the welding dust pollution.Due to the differences in operating space and welding skills, it is difficult to achieve satisfactory welding quality and appearance, thus affecting the overall quality of the project.
In addition, due to the groove pipe parts for finished products, the site needs small operating space, can be really achieved by the wall Angle installation, greatly reduce the difficulty of operation, thus saving the area, beautify the effect of pipeline installation.
The original characteristics of the pipeline will not be affected
Grooved pipe fittings are connected with only one groove extruded on the outer surface of the connected pipe by a grooving machine without damaging the inner wall structure of the pipe. This is the unique technical advantage of grooved pipe fittings.If the traditional welding operation, many of the inner wall of the anti-corrosion layer of the pipeline will be damaged.Therefore, galvanized pipe, lined plastic steel pipe, steel and plastic composite pipe shall not be connected by welding and flange, or it needs secondary treatment.
is conducive to construction safety
Adopting the connection technology of grooved pipe fittings, the site only needs the handle for cutting machine, grooving machine and button-tightening bolt, so the construction is easy to organize.And the use of welding and flange connection, need to be equipped with complex power cables, cutting machines, welding machines and oxygen and acetylene cylinders, etc., which brings complexity to the construction organization, and there are also leakage and fire hazards.At the same time welding and gas cutting produced by welding slag, inevitably fall into the pipeline, the use of easy to produce pipe valves and even equipment blockage, but also pollution of water quality in the pipeline.
In addition, welding and flange connection inevitably need a long time of high-strength high-altitude work, also prone to production safety accidents.
The system is stable and easy to maintain
Groove pipe fittings with unique flexible characteristics, so that the pipeline has the ability of anti-vibration, anti-contraction and expansion, compared with welding and flange connection, the stability of the pipeline system increases, more suitable for the change of temperature, so as to protect the pipeline valve, but also reduce the pipeline stress damage to the structure.
Economic analysis
Due to the simple operation of the connection of the grooved pipe fittings, it saves time and labor, so it has good economic benefits.Many articles have done economic analysis, that "the use of clamp connection, although the clamp of a single accessory price is higher, but the overall installation of the pipe network benefits than flange connection".In the comparison of the article will be the flange connection according to the secondary galvanized treatment (according to the requirements of the specification, which must be done).
