Heat exchanger steel tube mechanical properties

The mechanical properties of heat exchanger tubes are essential for ensuring their performance and reliability under various operating conditions. Below is a summary of the standard grades and their corresponding mechanical properties: - **Tensile Strength (MPa)** - **Yield Strength (MPa)** - **Elongation (%)** | Grade | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | |-------|-------------------------|-----------------------|----------------| | T11 | ≥415 | ≥170 | ≥30 | | T12 | ≥415 | ≥205 | ≥30 | | T22 | ≥415 | ≥205 | ≥30 | These values are based on the standards **ASTM A213** and **ASME SA213**, which define the requirements for seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. ![Global hardware network](http://i.bosscdn.com/blog/wjw.jpg) *Concerned about surprises?* **Labels:** Mechanical properties, Heat exchanger, Steel pipe, MPA, Yield strength **Previous:** What are the implementation standards for hot-rolled stainless steel light channel? **Next:** 50Mn steel bar plate type cold heading die steel Understanding these mechanical properties helps in selecting the right material for specific applications, ensuring safety, durability, and efficiency in industrial systems. Whether you're working with boilers, power plants, or chemical processing equipment, choosing the correct grade of heat exchanger tube is crucial. Always refer to the latest standards and consult with experts to avoid unexpected issues during installation or operation.

Bearing Housing

Bearing housings are modular assemblies designed to make it easy to install bearings and shafts, while protecting bearings, extending their operating life and simplifying maintenance.

Housings are available in many sizes, and generally fall into five standard categories: split plummer (or pillow) block housings, non-split plummer block housings, flanged housings, take-up housings and two-bearing housings. These products can be designed to meet specific duty requirements such as load, speed and operating environmental conditions.

Non-standard bearing housing designs can also be supplied to particular customer requirements: for example, where special shaft centre heights, unusual sealing arrangements or non-standard materials of construction may be specified.

If ease of installation and maintenance are prime considerations, then split plummer block housings are an excellent choice as they not only accommodate pre-assembled shafts, but also simplify bearing inspections and maintenance as the shaft does not need to be disassembled. These units are designed for self-aligning ball bearings, spherical roller bearings and CARB toroidal roller bearings. Non-split plummer block housings are preferred when there are heavy loads acting in a direction other than toward the support surface. They are also used when the housing has to be mounted from the end of the shaft.

We have specialized in producing US/EURO standard bearing housings more than 10 years, could help to design the bearing housing or produce the bearing housing according to your requirements. (OEM accepted)
