ท่อหุ้มเชิงกลคืออะไร

เครื่องกลห่มท่อเรียงราย is a type of pipe used in various industries, รวมถึงอุตสาหกรรมน้ำมันและก๊าซ, ปิโตรเคมี, และการใช้งานแรงดันสูงอื่นๆ. มันใช้ “cladding” – กระบวนการเชื่อมหรือหลอมรวมโลหะชนิดหนึ่ง (ผนังท่อเรียบไม่สเกล “cladding” วัสดุ) ไปที่อื่น (ผนังท่อเรียบไม่สเกล “ฐาน” วัสดุ) – to create a pipe that combines the คุณสมบัติทางกล ของ วัสดุฐาน with the corrosion resistance of the cladding material.

Features of Mechanical Clad Lined Pipe

1. ความต้านทานการกัดกร่อน

The cladding material is typically a corrosion-resistant alloy (ด้าย), เช่นสแตนเลส, INCONEL, or another nickel alloy. This provides the pipe with a high degree of resistance to corrosion, แม้ภายใต้สภาวะที่ไม่เอื้ออำนวย, such as high temperatures and pressures, and in the presence of corrosive substances.

2. ความแข็งแรงทางกล

The base material is typically a stronger, less expensive metal, such as carbon steel. This provides the pipe with the necessary strength and toughness to withstand the ความเครียดทางกล it will be subjected to in service.

3. ลดค่าใช้จ่าย

While the cladding material is often more expensive than the base material, using a clad pipe can still be more cost-effective than using a pipe made entirely of the cladding material. This is because the cladding is typically much thinner than the base material, so less of it is needed.

Process of Making Mechanical Clad Lined Pipe

The manufacture of mechanical หุ้มด้วยผ้า pipes usually involves the following steps:

1. การตระเตรียม: The surfaces of the base and cladding materials are thoroughly cleaned and prepared. This is necessary to ensure a good bond between the two materials.

2. พันธะ: The cladding material is bonded to the base material. This can be done through a variety of methods, รวมทั้ง รีดร้อน, พันธะระเบิด, หรือการเชื่อม.

3. การตรวจสอบ: The clad pipe is inspected to ensure that the bond between the base and cladding materials is sound and that the pipe meets all necessary specifications. This can involve a range of non-destructive testing methods, อย่างเช่น การทดสอบอัลตราโซนิก หรือ การทดสอบภาพรังสี.

4. เสร็จ: The pipe is then finished to the desired size and shape. This can involve cutting, ดัด, and/or forming the pipe.

เครื่องกลห่มท่อเรียงราย, with its combination of strength, ความต้านทานการกัดกร่อน, และความคุ้มค่า, is a valuable tool in industries where pipes are exposed to harsh conditions.

 

 

What are some other industries that use mechanical clad lined pipe?

Mechanical Clad Lined pipes, due to their enhanced durability and corrosion resistance, are used in a variety of industries that require the transport of aggressive materials, or where the pipes are exposed to extreme conditions. นี่คือตัวอย่างบางส่วน:

1. สารเคมีอุตสาหกรรม

ในโรงงานแปรรูปเคมี, pipes are often exposed to acids, ด่าง, and other corrosive substances. Mechanical Clad Lined pipes are used here due to their excellent corrosion resistance.

2. Nuclear Industry

The nuclear power industry uses these pipes in parts of their systems exposed to high radiation levels. The cladding material can help resist the corrosive effects of radiation.

3. Desalination Plants

Desalination plants, which convert seawater into fresh water, often use these pipes due to their resistance to the corrosive effects of salt water.

4. Pulp and Paper Industry

In the pulp and paper industry, pipes are often exposed to corrosive substances like black and green liquors. Clad pipes offer the necessary resistance to withstand these conditions.

5. อุตสาหกรรมอาหารและเครื่องดื่ม

Stainless steel clad pipes are often used in the food and beverage industry due to their resistance to a variety of substances and their ability to be easily cleaned and sanitized.

6. pharmaceutical อุตสาหกรรม

The pharmaceutical industry uses these pipes because they are resistant to a variety of chemicals and can be easily cleaned and sterilized, which is critical in environments where contamination must be avoided.

7. Power Generation Industry

ในโรงไฟฟ้า, especially those using fossil fuels, there are sections where pipes are exposed to high temperatures, แรงกดดัน, and corrosive substances. Clad pipes are used in these situations due to their superior strength and corrosion resistance.

จดจำ, the specific type of cladding material used can vary depending on the specific needs of the industry or application.
