Anti-corrosion steel pipe manufacturers for drainage projects

Hebei News Information, [Reporter Bi Editor] learned in March that the anti-corrosion pipe manufacturer for water supply and drainage projects [Manager Bi] Cangzhou Tianze Pipeline Co., Ltd. is a large-scale external anti-corrosion treatment manufacturer of buried steel pipes in Hebei, spiral steel pipes for tap water construction, tap water projects Use spiral steel pipes, large diameter spiral steel pipes for drinking water projects, B spiral steel pipes, special B spiral steel pipes for drinking water, anti-corrosion spiral steel pipes for natural gas pipelines, professional anti-corrosion spiral steel pipes for drinking water. Our factory has a large number of pipes all year round - the past of water supply pipes
Similar to the development of my country's building water supply and drainage profession, 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 a variety of varieties with rapid improvement and rapid development of sanitary standards. Ungalvanized steel pipes, which have been used for nearly 30 years, including 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 to save steel. Reinforced concrete pipes were promoted in the 1950s. , can withstand high working pressure, is corrosion-resistant, is cheap and durable, and will not reduce the water delivery capacity of the water pipe. However, it is heavy, has a hard and brittle texture, is afraid of collision, and has easy joint leakage. The pipe trench bottom must be flat and solid. The lack of accessories makes future maintenance more difficult, and the amount used is gradually decreasing. Plastic pipes have good anti-corrosion and earthquake resistance, a certain degree of tensile and bending elasticity, smooth surface, good hydraulic conditions, stronger freeze resistance than metal pipes, and light weight. Etc. Because the pressure of the pipe is not high enough, it is brittle and easy to age, and it is expensive, so it is only used for indoor small-diameter pipes.
The current situation of secondary water supply pipes
Price of anti-corrosion steel pipes for drinking water There are currently many types of water supply materials. Our focus is to introduce new indoor and outdoor water supply pipes, and to introduce some new ones that have been used in the past and have improved performance. Application points are introduced. 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, isolated from fire sources and away from heat sources.
This product is a thick build paint, which can be applied thickly without sagging. Generally, it can be applied without adding diluent after opening the barrel.
After the paint is stored for a long time, it will precipitate slightly and should be stirred before use.
After the paint is prepared, it should be cured for 10 minutes in summer and 1 hour in winter before construction. It is generally used up within 1 hour, otherwise the viscosity will thicken and it will be difficult to construct.
Unprotected steel pipes with unprotected 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. They have not been widely used in large and medium-sized outdoor water supply pipes due to cost reasons and other reasons.
The protective layer type currently includes metal protective layer type and non-metallic protective layer type. The commonly used metal protective layer type is the surface coating protective layer type and the surface lamination protective layer type. The most common type of surface coating protective layer is galvanized pipes. Galvanized pipes also include 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 stability. However, because the protective layer of cold-galvanized pipes is not dense enough, uniform and stable, and generally corrodes within a year of service life, red water and black water have a serious iron smell, and various harmful bacteria exceed the national drinking water quality standards. Domestic water supply has been implemented in various places. Pipes are prohibited. 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 currently produced includes steel composite stainless steel composite steel pipe, copper steel bimetal composite steel pipe, all of which use Physical method is to press the heated and softened thin-walled stainless steel pipe or cold thin-walled copper pipe on 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 heavy-duty anti-corrosion coating for the interpenetrating network of drinking water anti-corrosion steel pipes is a two-component coating, with Group A base material resin initiator and 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 structure, producing a synergistic effect. The network formed by the paint has strong adhesion, flexibility, and good resistance to acid, alkali, salt, and other corrosion medium. It further improves the toughness, strength, adhesion, anti-permeability and chemical inertness of the coating, giving the coating film better performance. It is a new polymer blending technology that improves the performance of the polymer through formation.
