THERMOWELLS, ĐẠI LÝ PHÂN PHỐI THIẾT BỊ CHÍNH HÃNG TEMPSENS TẠI VIỆT NAM

THERMOWELLS

Thermowells cung cấp sự bảo vệ cho các đầu dò nhiệt độ chống lại các điều kiện hoạt động không thuận lợi như ăn mòn
môi trường, tác động vật lý (ví dụ clinker trong lò nung) và khí hoặc chất lỏng áp suất cao. Việc sử dụng chúng cũng cho phép thay đổi đầu dò nhanh chóng và dễ dàng mà không cần phải "mở" quy trình. Nó là ống dẫn chất lỏng đầu kín được thiết kế để chèn
phần tử cảm biến nhiệt độ, và được cung cấp các phương tiện để gắn chặt với áp suất vào bình.

TYPES OF THERMOWELLS:

Threaded Thermowell:

Athreaded Thermowell has threads at its one end and is screwed into the process.

Thread can be of tapered or parallel type.

Parallel or tapered thread is made for convenient installation into a weld in fitting directly into the process.

Such a connection is suitable for smaller diameter well, which are not likely to be changed.

Socket Weld Thermowell:

A socket weld Thermowell is welded into a weldalet and a weld in Thermowell is welded directly into the process.

Welded connection can be used when the process is not corrosive and routine removal is not required.

High integrity is achieved and this technique is suitable for high temperature and pressure.

Flanged Thermowell:

Aflanged Thermowell has a flange collar which is attached to a mating flange.

Flanged connection is preferable if there is a need for more frequent well replacement such as high corrosion rates.

Fabricated Thermowell:

Fabricated thermowells are manufactured from tubes which are sealed by a solid welded tip at the process.

It means that the stem of thermowell is manufactured from tube and tip is made separately than both these parts are welded by utilizing suitable welding process.

The flange is also joined to this assembly by welding process.

Fabricated thermowells are generally recommended for low to medium process loads.

Bar stock Thermowell:

Such thermowell bodies are machined and drilled from solid bar stock.

This results in a non-welded water tight unit.

In this Immersion tip is also made by same material along with stem.

In such type of thermowell, no welding process is required for stem and tip production.

Flange can be weld according to requirement.

Bar-Stock thermowell is also known as “Solid drilled thermowell”.
