Introduction to the application fields and scenarios of stainless steel pipe fittings

Introduction to the application fields and scenarios of stainless steel pipe fittings:
I.Petroleum, chemical and energy industries
This is one of the fields with the most extensive application and strict requirements for stainless steel pipe fittings.
· Scene introduction:
· Oil and natural gas: pipeline systems for offshore drilling platforms, land oil extraction and refineries. Transport crude oil, natural gas, and all kinds of corrosive drilling mud and chemicals. High-grade 316/316L or even two-phase stainless steel pipe fittings are required to resist hydrogen sulfide, chloride and high-pressure environments.
· Chemical industry: In chemical plants, it is used to connect reactors, storage tanks and heat exchangers to transport strong corrosive media such as acids, alkalis and solvents. The requirements for the sealing and pitting resistance of pipe fittings are extremely high.
· Energy and electricity: boiler water supply systems and steam pipelines for thermal power plants; auxiliary pipeline systems for nuclear power plants; and heat collection pipe systems for solar photothermal power plants.
· Key values: safety, corrosion resistance, high pressure and high temperature resistance, ensure that no leakage occurs under harsh working conditions, and ensure production and environmental safety.

II. Food, beverage and pharmaceutical industries
This field has extreme hygiene requirements, and stainless steel (especially 304 and 316L) is the absolute first choice material.
· Scene introduction:
· Food processing: It is used to transport raw materials, semi-finished products and finished products on the production lines of dairy products, beer, beverages, meat, seasonings, etc. Pipe connection requires sterile pipe fittings, the inner wall is smooth and has no dead corners, and is easy to clean and disinfect (CIP in-situ cleaning).
· Pharmaceutical and biological engineering: used for pharmaceutical water (purified water, injection water) systems, process material pipelines, fermentation tank connections, etc. It is required that the pipe fittings have a very high finish, no toxic seepage, and can withstand repeated steam sterilization.
· Brewing industry: from fermentation tanks to filtration equipment to bottling lines, stainless steel pipes and fittings are used throughout the whole process to ensure that the flavor of wine is not contaminated by metal.
· Key values: hygienic, non-toxic, easy to clean, resistant to disinfectant corrosion, in line with FDA, GMP and other strict industry standards.

III. Construction, water supply and drainage and municipal engineering
· Scene introduction:
· Building water supply and drainage: used for cold and hot water supply systems for high-end hotels, hospitals, office buildings and residences. Compared with galvanized steel pipes, stainless steel water pipes will not rust, which can ensure the safety of drinking water in the "last kilometer".
· Fire sprinkler system: Stainless steel pipe fittings are used more and more in important fire pipeline systems because of their high strength and reliability.
· Municipal water supply: The key connection parts in the urban water supply network and the water treatment equipment pipelines in the water plant are gradually made of stainless steel to ensure a wide range of water quality.
· Building structure decoration: Stainless steel pipe fittings and pipes are also often used in stair handrails, guardrails, curtain wall support structures, etc., which are both functional and aesthetic.
· Key values: long life, low maintenance cost, environmental protection, hygiene and beauty.

Pressed pipe fittings and thin-walled stainless steel pipes
Introduction to the application scenario:
I. High-end building drainage system in coastal areas.
· Detailed introduction: The coastal air is rich in salt (chloride), which is extremely corrosive to metal pipes. The 316-material card pressure system has become the first choice of cold and hot water pipes for hotels, high-end residences, hospitals and sea view villas because of its excellent resistance to chlorine ion corrosion. Its installation is fast and the interior is smooth, which can ensure that the water quality is pure and rust-free for decades.
· Core advantages: strong corrosion resistance, fast installation, sanitary connection, long service life.

II. Process pipelines in the food and pharmaceutical industries.
Detailed introduction: In these industries, pipelines need to be frequently cleaned with chlorine-containing disinfectants (such as sodium hypochlorite) for CIP (in-situ cleaning). The card pressure system made of 316L (low-carbon version) can effectively resist the corrosion of disinfectants, and its inner wall of the pipe is smooth and has no dead angles, which meets the hygiene standards and prevents the growth of bacteria.
· Core advantages: chemical corrosion resistance, hygiene without dead corners, easy to clean and disinfect.

The jamming system made of 316 material can not only provide reliable sealing and corrosion resistance, but also be flexible in installation, suitable for complex experimental table layout.
· Core advantages: resistant to a variety of chemicals, good sealing, flexible installation.
