The scope of use of seamless steel pipe products
1. Structural seamless steel pipe (GB/T8162-1999): mainly used for general structure and mechanical structure. 2. Seamless steel pipe for conveying fluid (GB/T8163-1999): mainly used for conveying pipelines. For example central air conditioning, cold storage, gas, fire enginee...Read more -
Influence of strength anisotropy of UOE steel pipe on compressive strength
In the last 10 years, to transport natural gas, deep water research projects of laying pipelines on the seabed have been carried out. In the long-distance transportation of natural gas, the pipeline is required to have compressive strength against external water pressure under...Read more -
Large diameter hot rolled seamless steel pipe
High-frequency welded pipes are generally completed by processes such as cold rolling, high-frequency welding, and forming. It is a kind of seamed pipe. Seamless steel pipes are divided into hot-rolled seamless pipes and cold-drawn seamless pipes. Hot-rolled pipes are made by ...Read more -
Stainless Steel Precision Seamless Steel Tube
Precision steel pipe is a high-precision steel pipe material processed by cold drawing or hot rolling. Due to the advantages of no oxide layer on the inner and outer walls of precision steel pipes, no leakage under high pressure, high precision, high finish, no deformation in ...Read more -
How to avoid rusting of precision stainless steel pipe fitting
1. Do not contact with other metals, because stainless steel pipe fittings will be rusted by the attachment of dissimilar metals, such as screws, etc. Although it is not serious at the beginning, if you wipe it with a cloth and a neutral detergent, you will see rust. 2. Anothe...Read more -
Selection of submerged arc steel pipe and introduction of production process
Selection of submerged arc steel pipe: 1. For pipelines with high requirements for peak regulation, due to the uneven gas consumption of users and frequent fluctuations in pipeline pressure, the alternating stress on the steel pipe is very large, and the existing defects in th...Read more -
What are the details of thick-walled steel pipe before use
The welding method of thick-walled steel pipes should be selected according to the material and wall thickness of thick-walled steel pipes. Because different welding methods have different arc heat and arc force, different welding methods have different characteristics. For ex...Read more -
Advantages of plastic-coated steel pipes for fire water supply
In the case of no pipe blockage or water blockage, the plastic-coated steel pipe successfully solves the problems of coating burial, steel pipe corrosion, scaling, etc., and prolongs the service life of the fire water supply pipe. Epoxy powder anti-corrosion steel pipe has goo...Read more -
Routine maintenance and production process of thick-walled straight seam steel pipe
The advantage of thick-walled straight seam steel pipe is that the online heat treatment process of the weld eliminates the welding stress, refines the metallographic grains of the heat-affected zone, and improves the physical and mechanical properties. The direction of struct...Read more
