Forest Fire Truck Introduction

  There are two types of forest fire trucks . One is a fire engine and the other is a RV. Today, the forest fire truck RV is the main engine . The forest fire truck is based on a special vehicle chassis. The main features of the RV refitting are as follows:

â—†Function

This vehicle is designed for field workers and can meet the needs of five to eight staff members camping, working in the field, and convening small meetings.

â—†Features

1. The cabin of the camping car is made of big square cabin technology, which is solid and beautiful.

2. The compartments are divided into three compartments, which are conference rooms, lounges and toilets. They are connected to each other through partition doors.

3. The conference room is equipped with conference tables, folding chairs, single beds, desks, nightstands, car refrigerators, air conditioning, LCD TVs, DVDs and other equipment, which can be used by five to eight staff to hold small meetings; a single bed For staff to rest.

4. There are folding chairs, folding tables, air conditioners, LCD TVs and other equipment in the lounge for 4 staff to camp and rest.

5. Toilets equipped with hand-wash basins, on-board toilets, clean water tanks, sewage tanks and other facilities to meet the staff washing requirements.

6. Pull out ladders and handrails on the outside of the car to facilitate personnel.

7. The luggage compartment and distribution box are installed in the lower part of the cabin to fully utilize the space of the cabin. Distribution box set socket, you can use 220V or 380V external power supply.

8. Install mechanical legs below the cabin and prop up the body when camping to make the cabin more stable.

Duplex Stainless Steel Overview

Duplex Stainless Steels, also referred to as austenitic-ferritic stainless steels, are a family of grades with about equal proportions of ferrite and austenite. These steels have a duplex microstructure which contributes to their high strength and high resistance to stress corrosion cracking. Due to their high content of chromium, nitrogen and molybdenum, duplex steels offer good resistance to local and uniform corrosion. Duplex stainless steels have good weldability.


Today, modern duplex stainless steels can be divided into three groups:
Lean Duplex such as LDX2101
Standard Duplex such as 2205, the work-horse grade accounting for more than 80% of duplex usage
Super Duplex such as Ferralium 255 and Zeron 100 and LDX2507

Of the duplex grades, duplex 2205 is the most widely used. However, the super duplex steels like Zeron® 100 and LDX2507 are excellent for servicing severe corrosive environments, such as offshore and marine applications. Lean duplex 2101 is available as an economic alternative to 300 series stainless steels.
