What are the common defects in the weld zone of spiral welded steel pipes
Common defects in the weld zone of spiral welded steel pipes include porosity, hot cracking, and undercut. Porosity in the weld seam of spiral welded steel pipes not only affects the tightness of the weld seam, causing pipe leaks, but also becomes a corrosion initiation point,...Read more -
How to solve the deformation problem of the spiral submerged arc welded steel pipes
Rotary drilling of spiral submerged arc welded steel pipes begins in soft strata. Under the action of the tricone cone, the drill bit first induces elastic shear deformation of the strata, which is then removed under the pressure of the tricone cone. In the simulated environme...Read more -
What are the key technical points of the precision steel pipe extrusion molding process
Precision steel pipe extrusion molding is a core manufacturing technology that uses external force to drive the controllable plastic deformation of the billet metal in the mold cavity, ultimately obtaining a steel pipe substrate with high dimensional accuracy, excellent surfac...Read more -
What are some common methods for corrosion protection of 3PE anti-corrosion steel pipes
1. Steel pipe corrosion protection generally uses two main methods: external coating and cathodic protection. 2. Although most of the surface of the steel pipe is covered by the coating, even a small leak can lead to an incredible corrosion rate, even perforation or cracking. ...Read more -
What are the characteristics of coated steel pipes and the transportation requirements for hot-dip plastic-coated steel pipes
Internally and externally coated steel pipes have epoxy resin coating on both the inner and outer walls, resulting in a smooth surface, reduced fluid resistance, increased flow rate, no scale formation, and minimal microbial growth. Through plastic coating treatment to withsta...Read more -
How are fire-fighting grooved steel pipe fittings manufactured
Fire-fighting grooved steel pipe fittings are steel pipe fitting products used in fire-fighting pipelines, connected by clamp-type fittings. They are a general term for components in grooved pipelines that serve functions such as connection, control, transformation, flow diver...Read more -
What precautions should be taken when welding steel pipes
Welding steel pipes is a common process that plays an important role in construction, manufacturing, and repair. However, several key points need to be considered to ensure welding quality and safety. First, proper preparation before welding steel pipes is crucial. Before star...Read more -
What are the precautions for machining welded steel pipes
First, clean the surface of the steel pipe. Before welding, ensure the surface of the steel pipe is clean and free of impurities such as oil, paint, water, and rust. These impurities may affect the smooth progress of the welding process and may even cause safety problems. Tool...Read more -
