Product Description

Product Description

321 stainless steel is a Ni Cr Ti austenitic stainless steel with properties very similar to 304, but due to the addition of titanium metal, it has better resistance to crystal corrosion and high-temperature strength. Due to the addition of titanium metal, it controls the formation of chromium carbide.

 

321 stainless steel has better high-temperature stress fracture performance and high-temperature creep resistance than 304 stainless steel in terms of stress mechanical properties.

 

Applied to outdoor machinery in chemical, coal, and petroleum industries with high requirements for corrosion resistance, heat-resistant parts in building materials, and parts with difficulty in heat treatment,
such as:
1 Petroleum waste gas combustion pipeline
2 Engine exhaust pipe
3 Boiler shell, heat exchanger, heating furnace components
4 Silencing components for diesel engines
5 Boiler pressure vessel
6 Chemical transport vehicle
7 Expansion joint
8 Spiral welded pipes for combustion furnace pipelines and dryers

Product Process

Manufacturing Facility

Our company is equipped with a number of automatic ring weldingmachine, semi-automatic wave expansion machine, bending machine.flaring machine, straightening machine
Straightening machine, flat head machine, coil air pressure machineand other equipment. Ensure customer custom size accurate, docking
Neat, 100% pressure test 8kg 15s, to ensure that customers use pipewithout leakage, no porosity.

Main Process Requirements:

Our 2B raw materials are mainly from Zhangpu, TiSCO, Baoxin and other famoussuppliers. The base materials and weld seam of the pipe undergo the solidsolution treatment integrally. The outer diameter tolerance and inner weld residualheight are strictly controlled to ensure no internal weld traps exist. Each piece issubjected to a 100% one-by-one pressure detection at 15 kg pressure for 15seconds. The entire length of the pipe measures 12 meters with throw light onboth inside and outside surfaces, followed by an 18-meter tube pressure test.
