Zhuoxi supplies TP304 stainless steel pipe and 32168 stainless steel seamless pipe with complete specifications

Introduction to stainless steel pipe
  Stainless steel pipe is a kind of economical section steel
It is an important product in the iron and steel industry
It can be widely used in life decoration and industry
Many people in the market are used to make stair handrails, window guards, railings, furniture and so on
There are two common materials: 201 and 304
Accounting for about 8% - 16% of the total steel, it is widely used in the national economy
Because the steel pipe has a hollow section, it is suitable for the transmission pipeline of liquid, gas and solid; At the same time, compared with round steel with the same weight, steel pipe has large section coefficient and high flexural and torsional strength, so it has also become an important material in various machinery and building structures
Structures and components made of stainless steel tubes have larger section modulus than solid parts under the condition of equal weight
Therefore, stainless steel pipe itself is a kind of economical section steel to save metal
It is an important part of high-efficiency steel, especially in oil drilling, smelting and transportation industries
Secondly, it is in great demand, followed by geological drilling, chemical industry, construction industry, machinery industry, aircraft and automobile manufacturing, boiler, medical equipment Furniture and bicycle manufacturing also need a large number of various steel pipes
With the development of new technologies such as atomic energy, rocket, missile and aerospace industry, stainless steel pipe plays an increasingly important role in national defense industry, science and technology and economic construction

  Stainless steel pipe is safe, reliable, hygienic, environmentally friendly, economical and applicable
The thin wall of the pipe and the successful development of new reliable, simple and convenient connection methods make it have more irreplaceable advantages of other pipes
It will be more and more applied in engineering, more and more popular and promising

  Because stainless steel has many ideal properties required by building materials, it can be said to be unique in metals, and its development continues
In order to make stainless steel more neutral in traditional applications, the existing types have been improved, and new stainless steel is being developed to meet the strict requirements of advanced architectural applications
Due to the continuous improvement of production efficiency and quality, stainless steel has become one of the cost-effective materials selected by architects

  Stainless steel integrates performance, appearance and use characteristics, so stainless steel will still be one of the building materials in the world
With China's reform
  With the implementation of the opening-up policy, the national economy has achieved rapid growth, and a large number of urban houses, public buildings and tourism facilities have been built, which puts forward new requirements for hot water supply and domestic water supply
In particular, people pay more and more attention to the problem of water quality, and the requirements are also increasing
Galvanized steel pipe, a common pipe, will gradually withdraw from the historical stage under the influence of relevant national policies because of its corrosiveness
Plastic pipe, composite pipe and copper pipe have become common pipes in the pipeline system
However, in many cases, stainless steel pipe has more advantages, especially the thin-walled stainless steel pipe with wall thickness of only 0
6 ~ 1
2mm
In high-quality drinking water system, hot water system and water supply system that puts safety and sanitation first, it has the characteristics of safety, reliability, sanitation, environmental protection, economy and applicability
It has been proved by engineering practice at home and abroad that it is one of the new pipes with comprehensive performance, energy saving and environmental protection in water supply system
It is also a very competitive water supply pipe, which will play an incomparable role in improving water quality and improving people's living standards

  Due to the rapid development of various types of steel pipes and composite water supply pipes in the past century, they can not fully meet the requirements of various types of water supply pipes in the country
Therefore, relevant experts predict that building water supply pipes will return to the era of metal pipes
According to foreign application experience, thin-walled stainless steel pipe is recognized as one of the pipes with comprehensive properties in metal pipe
Thin wall stainless steel pipe, which was only produced and used in China in the late 1990s, is a new family emerging in the field of pipe materials
It has been widely used in the pipeline of building water supply and direct drinking water

  Thin wall stainless steel pipe is durable and has been recognized by the engineering community, and relevant parties are starting from reducing the wall thickness and reducing the price, so as to facilitate further promotion
In particular, the price of small-diameter stainless steel pipe is not high, so the supporting connection method, the reliability and price of pipe fittings are the main factors determining its development
Domestic developers in Sichuan, Guangdong, Zhejiang, Jiangsu and other places have independently developed connection technology and pipe fittings, which are promising pipes
The Ministry of construction and relevant departments also attach great importance to this new type of pipe
According to the document of China technology market management promotion center and Guo Ke Shi Zi [2001] No
71, on the promotion and application of & ldquo; High diameter to wall ratio and high precision stainless steel medium and high pressure water supply pipes and supporting fittings and special technology & rdquo; It was learned from the notice that the popularization and application of thin-walled stainless steel pipe technology and product is of great significance to improve the grade of modern buildings in China and improve and ensure the water quality of water supply

  At the same time, the Ministry of construction attaches great importance to the promotion and application of thin-walled stainless steel pipes
The industry standard of thin wall stainless steel water pipe was issued and implemented in 2001
Relevant technical specifications and installation Atlas of pipeline engineering have been issued by the Ministry of construction and are being prepared by Tongji University
At present, there are professional manufacturers producing thin-walled stainless steel pipes in Sichuan, Guangdong, Zhejiang, Jiangsu and other places, and the products have become mature
Therefore, the time for popularization and application has come

 
There are various connection modes of stainless steel pipes
The common types of pipe fittings are compression type, compression type, union type, push type, push thread type, socket welding type, union flange connection, welding type and derivative series connection mode combining welding with traditional connection
These connection modes have different application ranges according to their different principles, but most of them are easy to install, firm and reliable
Most of the sealing rings or gaskets used for connection are made of silicone rubber, nitrile rubber and EPDM that meet the requirements of national standards, which eliminates the worries of users

 
Clamping connection steps
1
Pipe breaking: cut off the pipe according to the required length
When breaking the pipe, do not use too much force to prevent the pipe from being out of round

2
Deburring: after the pipe is cut off, the burr shall be removed to avoid cutting the sealing ring

3
Marking: in order to fully insert the steel pipe into the socket of the pipe fitting, the insertion length must be marked and marked at the pipe end

4
Assembly: the sealing ring shall be correctly installed in the U-shaped groove of the pipe fitting, insert the pipe into the socket of the pipe fitting and wait for crimping

5
Crimping: when crimping, the convex part of the pipe fitting is placed in the concave groove of the die, and the jaw is perpendicular to the pipe axis

6
Inspection: after crimping, use special gauge to check the crimping size
