SB171  压力容器 耐蚀性，有良好的力学性能

ASME SB-171/SB-171M-2017属于美标压力容器，冷凝器和热交换器的铜合金板和板C46500属于美标海军黄铜，执行标准：ASME

SB-171/SB-171M-2017。

C46500锡黄铜在海水中有高的耐蚀性，有良好的力学性能，冷加工时有冷脆性，只适于热压加工，可切削性好，易焊接和纤焊，但有腐蚀破裂（季裂）倾向。用于制造与海水、汽油等接触的零件。

压力容器是指盛装气体或者液体，承载一定压力的密闭设备。压力容器的种类很多，如储气罐、气瓶、反应釜、蒸发器等。

SB171压力容器的设计、制造、安装、使用、检验、修理和改造等环节都必须遵守相关的安全规定和标准，以确保其安全可靠地运行。压力容器在工业、医疗、航空航天、能源等领域都有广泛的应用。

SB171压力容器的安全规定和标准包括但不限于以下内容：

ASME SB-171/SB-171M-2017 Copper alloy plates for pressure vessels, condensers and heat exchangers and plates C46500 are American Standard Naval brass, executive standard: ASME

SB-171/SB-171M-2017.

C46500 tin brass in seawater has high corrosion resistance, has good mechanical properties, cold processing cold brittleness, only suitable for hot pressing processing, good machinability, easy welding and fiber welding, but there is a tendency of corrosion cracking (seasonal cracking). Used to make parts that come into contact with seawater, gasoline, etc.

Pressure vessel refers to the sealed equipment containing gas or liquid and bearing a certain pressure. There are many kinds of pressure vessels, such as gas storage tanks, gas cylinders, reactors, evaporators and so on.

The design, manufacture, installation, use, inspection, repair and modification of SB171 pressure vessels must comply with relevant safety regulations and standards to ensure their safe and reliable operation. Pressure vessels are widely used in industrial, medical, aerospace, energy and other fields.

SB171 Safety regulations and standards for pressure vessels include, but are not limited to, the following:

1. Design specifications: The design of pressure vessels must comply with relevant national standards and industry standards, such as GB150 "pressure vessels", JB4732 "Steel pressure vessels - Analysis and design standards", etc.

2. Manufacturing standards: The manufacture of pressure vessels must comply with relevant national standards and industry standards, such as GB151 "shell and tube heat exchanger", JB/T4745 "Titanium welded container" and so on.

3. Installation standards: The installation of pressure vessels must meet the relevant national standards and industry standards, such as GB50273 "Boiler installation engineering construction and acceptance Code", GB50231 "Mechanical equipment installation engineering construction and acceptance general code" and so on.

4. Use regulations: The use of pressure vessels must comply with relevant national standards and industry standards, such as TSG21 "Fixed pressure vessel safety Technical Supervision Regulations", GB18442 "Hazardous chemical Packaging, container safety Technical Regulations" and so on.

5. Inspection standards: The inspection of pressure vessels must comply with relevant national standards and industry standards, such as NB/T47013 "Non-destructive testing of Pressure equipment", GB/T12130 "Technical Specifications for Medical Gas pipeline Engineering" and so on.

6. Repair and renovation standards: the repair and renovation of pressure vessels must comply with relevant national standards and industry standards, such as TSG21 "Fixed pressure vessel safety technical supervision Regulations", GB150 "pressure vessels" and so on.

The above are some common safety regulations and standards for pressure vessels, which may vary by country, industry and application field. When using pressure vessels, the relevant safety regulations and standards must be strictly observed to ensure their safe and reliable operation.
