Anti-corrosion steel pipe manufacturers for drainage projects

Hebei News Information [Reporter Bi Editor] It was learned that the anti-corrosion pipe manufacturer for water supply and drainage projects [Manager Bi] Cangzhou Tianze Pipeline Co., Ltd. is a large external anti-corrosion treatment manufacturer of buried steel pipes in Hebei Spiral steel pipes for tap water construction Spiral steel pipes for drinking water projects Large-diameter spiral steel pipe for engineering QB spiral steel pipe for drinking water QB spiral steel pipe for natural gas pipeline anti-corrosion spiral steel pipe for drinking water professional anti-corrosion spiral steel pipe Our factory has a large number of pipes all year round - the past of water supply pipes
With the development of my country's construction water supply and drainage profession Similarly, my country's water supply pipes have also experienced the past of a single variety with low sanitary standards and slow development, and the present of diverse varieties with rapid improvement and rapid development of sanitary standards. The non-galvanized steel pipes that have been used for nearly 30 years, including the galvanized steel pipes that were once regarded as one of the symbols of improving construction standards, have now been partially phased out in most provinces in order to save steel. The reinforced concrete pipes promoted in the 1950s can withstand higher High working pressure, corrosion resistance, low price and durability, which will not reduce the water delivery capacity of water pipes. However, they are heavy, hard and brittle, and are afraid of collisions. The joints are prone to leakage, and the bottom of the pipe trench is flat and solid. The lack of spare parts makes future maintenance more difficult. Now the usage is gradually increasing. Reduced plastic pipes have good anti-corrosion and earthquake resistance, a certain degree of tensile and bending elasticity, smooth surface, good hydraulic conditions, good frost resistance, and lighter weight than metal pipes. Because the pipes are not strong enough, are brittle and easy to age, and are expensive, they are only used for indoor small-diameter pipes.
The current situation of secondary water supply pipes
Price of drinking water anti-corrosion steel pipes There are currently many types of water supply materials. Our focus is to introduce new indoor and outdoor water supply pipes and use them in the past and present some new application points with improved performance. Give an introduction. The following is a summary of the main use places of pipes in two categories
Outdoor water supply pipes, drinking water anti-corrosion steel pipe prices
Precautions
The product should be stored in a cool, ventilated and dry place to isolate fire sources and away from heat sources.
.This product is a thick-lay paint that can be applied thickly without sagging. Generally, it can be applied without adding diluent after opening the barrel.
.The paint will precipitate slightly after being stored for a long time and should be stirred before use.
. After the coating is prepared, it will be cured for 10 minutes in summer and matured in winter in 1 hour. Construction after 1 hour is generally used up within 1 hour, otherwise the viscosity will thicken and it will be difficult to construct.
Unprotected steel pipes with or without protective layers were usually called ungalvanized steel pipes in the past. Textured steel pipes mainly refer to stainless steel seamless steel pipes and stainless steel welded steel pipes that have not been widely used in outdoor large and medium-sized pipeline water supply due to cost connection and other reasons.
There are currently two protective layer types: metal protective layer type and non-metallic protective layer type. Metal protective layer type and commonly used surface coating protective layer type, surface lamination protective layer type. The most common types of surface coating protective layer are galvanized pipes, galvanized pipes, cold-dip galvanized pipes and hot-dip galvanized pipes. Hot-dip galvanized pipes are still widely used because of the dense and uniform protective layer, strong adhesion and better stability. However, cold galvanized pipes generally have a service life of less than a year and corrode due to insufficient protective layer, uniformity, and poor stability. Red water, black water, and iron odor are serious, and various harmful bacteria exceed the national drinking water quality standards. Their use in domestic water supply pipelines has been banned in various places. The surface lamination protective layer type can also be divided into physical covering type composite steel pipe and covering type composite steel pipe according to different production processes. Among them, the physical covering type composite steel pipe has currently produced steel composite stainless steel composite steel pipe, copper steel bimetal composite steel pipe, all of which use physical coating. Method: The heated and softened thin-walled stainless steel pipe or cold thin-walled copper pipe is pressed onto the inner wall of the steel base pipe through a certain process. The specifications of these two pipes are and. Physically covered composite steel pipe pipe connections are often made with special fittings. Covered composite steel pipes include bimetal composite pipes. The interpenetrating network heavy-duty anti-corrosion coating for drinking water anti-corrosion steel pipes is a two-component coating, Group A base material, resin initiator, Group B base material, active monomer catalyst. When Group A and Group B are mixed in equal amounts, the three networks interpenetrate at the molecular level to form an interpenetrating polymer network (the structure produces a synergistic effect. The network formed by the paint has strong adhesion, strong flexibility, good resistance to acid, alkali, salt and other corrosive media. Further It improves the toughness, strength, adhesion, anti-permeability and chemical inertness of the coating, giving the coating film better properties. It is a new type of polymer blending technology to improve the properties of polymers through formation.
