Description

Henan Liwei Pipeline Equipment Co., ltd. (the former Zhengzhou Liwei Rubber Products Co., Ltd.) located at Shangjie District. Zhengzhou city is a manufacture specializing in processing various steam, water, windpipe expansion and compensation joints, and a main base for producing rubber ,metal and non-metallic pipe joints, It is also the appointed enterprise by the former chemical industry ministry .national construction ministry and general petrol chemical company member unit China Water Supply Association and power Equipment Network Union ,and joints production unit recommended by China Water Association and National Metallurgy Ministry.

Rubber lining pipeline equipment:

lining plastic container is on its inner surface according to certain technical requirements affixed lining corrosion resistant rubber sheet, after vulcanization forming. Can be isolated from acid and alkali salt and acid water contact with the metal surface, to protect metals from corrosion, and guarantee the system security, reliable operation. Is characterized by high strength, corrosion resistance, is widely used to transport corrosive medium or corrosive pipeline of solid particles, conform to the requirements of the HG*******3 standard, rubber pipe, rubber lining steel pipe, pipe fittings at the same specification with inspecting &controlling.

Main application range:

Chemical industry the container of acid and alkali medium, reaction kettle, pipe anti-corrosion;

Power plant desulfurization device in the washing tower, flue, airway, and various kinds of tank lining;

Truck scale and metal surface treatment and coating;

All kinds of anticorrosive coating used to transport liquid in the tank trucks, etc;

Other corrosive medium in the field of anti-corrosion treatment.

Lining plastic pipe equipment

Inspecting &controlling in high-quality carbon steel as matrix and excellent chemical stability of thermoplastic plastic is made through special processing technology. The product has high strength, corrosion resistance, good performance, no cracking, not aging, wide applicable scope, long service life, convenient installation and maintenance, etc.

Polyethylene (PE) steel line can

Performance: media working temperature: *5 — *5

Medium pressure:positive pressure 0.6 Mpa, 2.0 Mpa; Negative pressure is *5 kpa at room temperature

Corrosion resistance: the non oxidizing acid (such as hydrochloric acid, thin sulfuric acid, hydrofluoric acid), dilute sulfuric acid, alkali and salt solution has good corrosion resistance, but not resistant to sulfuric acid, nitric acid and other strong oxidizing corrosion. The general corrosion resistance good organic solvent, room temperature.

The steel liner of polypropylene (PP), PP, PO) can

Performance:media working temperature: *5 — **0

Medium pressure:positive pressure 0.6 Mpa, 2.5 Mpa; Negative pressure is *4 kpa at room temperature.

Corrosion resistance:except for nitric acid, fuming sulfuric acid, chlorosulfonic acid and other strong oxidizing acid and most organic and inorganic acid, alkali, salt, good resistance to corrosion of stress corrosion, below *0% nitric acid, formic acid, acetic acid, *6% hydrochloric acid, *0% below the hydrobromic acid, dilute hydrofluoric acid, various concentration of sulfuric acid, boric acid, butyric acid, alkali, mercury, and the vast majority of salt air, NH3, CO2, CO and NO2, HCL gas corrosion, etc.
