Does the galvanized steel pipe need to be rust removed during use? This is an important question regarding steel pipe maintenance. In practical applications, rust removal and maintenance of galvanized steel pipes are crucial. First, the characteristics of galvanized steel pipes Galvanized steel

1. Anti-corrosion performance of galvanized square steel pipe Galvanized square steel pipe is obtained by hot-dip galvanizing ordinary square steel pipe, and its surface is covered with a layer of zinc. This layer of zinc can effectively prevent the square steel pipe from contacting the external en

When we mention DN70 steel pipe, the first thing we need to understand is that "DN" here stands for the nominal diameter (Nominal Diameter), which is a term in pipeline engineering used to describe the inner diameter of the pipe. "70" refers to the specific value of this size, usually in millimeters

1. The wall thickness of stainless steel pipes has an important impact on their pressure resistance. In the steel industry, stainless steel pipe is a common material and is widely used in construction, chemical industry, medical equipment, and other fields. The wall thickness of stainless steel pip

Precision seamless steel pipe, many people in the construction industry should know that it is a high-precision steel pipe material, mainly used to produce pneumatic or hydraulic components, such as cylinders or cylinders, with strong pressure resistance and lightweight, and is generally used to man

3PE anti-corrosion straight seam steel pipe is a pipeline material widely used to transport oil, gas, and water resources. It has good corrosion resistance and durability and is suitable for use in various environmental conditions. 1. Characteristics of 3PE anti-corrosion straight seam steel pipe

Large-diameter seamless steel pipes are steel products formed by cold processing such as cold drawing and cold rolling. The state in which they are delivered directly without any heat treatment is called cold drawn or cold rolled state. Compared with the hot-rolled (forged) state, steel in the cold-

Three-oil and two-cloth anti-corrosion steel pipes use three-layer coating oil technology and two-layer weaving technology to give the surface extremely strong anti-corrosion properties and can be used for a long time in harsh environments without being affected by external corrosion. This three-lay

(1) Spraying (throwing) rust removal uses a high-power motor to drive the spraying (throwing) blades to rotate at high speed so that steel sand, steel shots, wire segments, minerals, and other abrasives spray (throw) the surface of the steel pipe under the action of centrifugal force. ) shot treatme

1. The arc starting method of stainless steel pipe fittings adopts the reflow method, and the arc closing method adopts the method of filling the arc crater. The arcing process should be completed within the slope, and arcing and arcing cannot be performed on the surface of the busbar of pipes and f

1. Angle steel and channel steel should be stacked in the open air, that is, the mouth should be facing down. I-beams should be placed upright, and the I-beam surface of the steel should not be facing up to avoid water accumulation and rust. 2. Corresponding passages should be left between stacks.

Large diameter thick wall seamless steel pipes are mainly reflected in: 1. Large diameter: It is generally believed that those with diameters above 219 are large-diameter seamless pipes, seamless steel pipes are large-diameter seamless pipes, those with diameters less than 76 are small-diameter sea

Steel bending pipe processing and forming technology 1. Die forging. For socket welding and threaded tees, crosses, elbows, and other small pipe fittings, the shapes are more complex and should be manufactured by the die forging process. The die forging blank should be rolled profiles, such as bars

1. The principal requirement for stacking spiral steel pipes is to stack them according to types and specifications on the premise of ensuring stable stacking and ensuring safety. Different types of materials should be stacked separately to prevent confusion and mutual erosion; 2. It is prohibite

The processing methods of 3pe anti-corrosion steel pipes are generally divided into two types: winding type and round die covering type; both are composed of 3-layer structure: the first layer of epoxy powder (FBE>100um), the second layer of adhesive (AD) 170~250um, The third layer of polyethylen

Cleaning methods for large diameter steel pipes: 1. Shot blasting and rust removal: A high-power motor drives the blades to rotate at high speed, so that steel sand, steel shots, wire segments, minerals, and other abrasives are sprayed and blasted on the surface of the steel pipe under the action o

If the spiral steel pipe for water transportation is to transport tap water or drinking water, the inner wall is generally made of IPN8710 non-toxic anti-corrosion coating, and the outer wall is made of epoxy coal pitch anti-corrosion. Of course, it can also be coated with internal and external plas

Characteristics of large-diameter straight-seam plastic-coated steel pipes: Its characteristics combine the characteristics of straight-seam steel pipes and the characteristics of epoxy resin. 1: Characteristics of straight seam steel pipes: Straight seam steel pipes have a simple production proc
