Product Description

Steam Trap Product Introduction & Technical Specifications

1. Product Overview

A steam trap, also known as a steam separator, is a critical automatic valve in steam systems. It automatically discharges condensate, air and non-condensable gases while effectively preventing steam leakage.

Its core functions include ensuring efficient heat transfer of steam equipment, preventing pipeline water hammer, avoiding equipment corrosion, and saving steam energy. It is widely used in all industrial and civil fields that use steam, such as petrochemical, power, food, textile, and HVAC industries.

2. Technical Specifications

2.1 Nominal Diameter (DN)

Standard range: DN15 ~ DN100 (1/2" ~ 4")

Common sizes: DN15, DN20, DN25, DN32, DN40, DN50

2.2 Nominal Pressure (PN/Class)

GB standard: PN16, PN25, PN40, PN63, PN100

ASME standard: Class 150, Class 300, Class 600

High-pressure type: Up to 42 MPa (special for power stations)

2.3 Working Temperature

Cast iron: 220

Cast steel: 450

Stainless steel: 550

2.4 Discharge Capacity

Small: 50 ~ 500 kg/h

Medium: 1 ~ 10 t/h

Large: 10 ~ 100 t/h

3. Main Component Materials

3.1 Body Materials

Gray cast iron (HT200/HT250): Suitable for PN16, 220, and general non-corrosive environments.

Ductile iron (FCD450): Suitable for PN25, 350, with higher strength than ordinary cast iron.

Cast steel (WCB/A105): Suitable for PN40 ~ PN100, 450, medium and high pressure conditions.

Stainless steel (304/316L): Suitable for PN40, 550, corrosion-resistant, and meets food/pharmaceutical grade requirements.

Chromium-molybdenum steel (15CrMo/12Cr1MoV): Designed for high temperature and high pressure scenarios, especially for power station boilers.

3.2 Internal Component Materials

Float ball: 304/316 stainless steel

Seat / disc: SUS440C, Stellite alloy (hardness HRC60)

Bimetallic strip: Nickel-iron alloy, manganese-copper alloy composite layer

Bellows: 316L, Hastelloy alloy

3.3 Sealing Materials

Hard seal: Stellite overlay, hard alloy (for high temperature and high pressure conditions)

Soft seal: PTFE, fluororubber (200, low leakage)
