Surface cleaning method of seamless steel tube: 1. Cleaning Use solvents and emulsions to clean the steel surface to remove oil, grease, dust, lubricants and similar organic substances, but it cannot remove rust, oxide scale (corrosion products formed by oxidation), welding flux, etc. on the steel surface, so It is only used as an auxiliary means in anti-corrosion production….
Read MoreSeamless tube is a steel pipe that is perforated from a whole round steel and has no welds on the surface. According to the production method, seamless tubes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel tubes, extruded seamless steel tubes, and pipe jacking. Seamless steel pipes are mainly used as petroleum…
Read MoreOil casing pipe is also called special oil pipe, which is mainly used for the drilling of oil and gas wells and the transportation of oil and gas. It includes oil drilling pipes, oil casings, and oil sucking pipes. Oil drill pipes are mainly used to connect drill collars and drill bits and transmit drilling power. The oil casing…
Read MoreThe control of the wall thickness of the steel pipe is a difficult point in the production of the steel pipe. The measures to improve the accuracy of the wall thickness of the seamless tube in the production mainly include the following aspects: 1. Tube billet heating The heating should be uniform, and it is forbidden to rapidly increase…
Read MoreThe production process of seamless steel pipes is relatively cumbersome and rigorous. After the seamless steel pipe is produced, certain tests must be carried out. Do you know the flattening test method and steps of the seamless steel pipe? 1) Flatten the sample: 1. The sample is cut from any part of the seamless steel pipe that has passed…
Read MoreSubmerged arc welding technology is the welding process of SSAW steel pipe and LSAW steel pipe. During the welding process, in addition to insufficient penetration, burn-through and poor formation caused by improper welding process parameters, there will also be pores, slag inclusions, cracks, etc. Defects. This article mainly introduces the main reasons and preventive measures for porosity in submerged…
Read MoreDuring the rolling process of seamless steel pipes, due to the influence of the stability of the machine and peripheral equipment and the uncertainty factors in the production process, the product dimensions often exceed the tolerance range specified in the product standard. The situations are as follows: 1. Uneven wall thickness 1)Features: The wall thickness of the steel pipe…
