The invention belongs to the technical field of casting, and relates to a size design method of a large thin-wall ball valve, which comprises the following steps of: marking a plurality of measuring points on the inner surface and/or the outer surface of the ball valve; Measuring the ball valve radius value of each measuring point; Subtracting the ball valve radius design sticking value of the corresponding angle measuring point from the ball valve radius value of the measuring point and the ball valve radius mold deviation value of the measuring point to obtain a deformation value; Adding thedeformation values to obtain the deformation sum value of the same angle measurement point, and dividing the deformation sum value of the same angle measurement point by the number of the same anglemeasurement points to obtain a deformation mean value of the same angle measurement point; Fitting the mean value of the deformation amounts of the angle measurement points through data statistical analysis software to obtain a formula of the anti-deformation process design sticking amount; According to the method, the sticking amount of each radius value of the ball valve is calculated by adopting a sticking amount formula designed by adopting a reverse deformation process, and the size process design of the ball valve is performed, so that the production period is remarkably prolonged and the cost is saved through the reverse deformation size process design of the method.

The invention relates to a manufacturing process of a high-pressure boiler pipe. The manufacturing process comprises two aspects of smelting a stainless steel blank and manufacturing a steel pipe. When a stainless steel blank is smelted, the carbon content in the corresponding steel grade is increased, and the contents of Ti and Nb in the steel grade containing Ti and Nb are strictly controlled. In the steel pipe manufacturing process, the respective hot tapping temperature of different steel types is controlled; the cold deformation is controlled to be 55% or below; and carrying out heat treatment at a proper softening temperature of the product and a proper solid solution temperature of the finished product. The high-pressure boiler steel pipe manufactured according to the manufacturing process provided by the invention has the advantages of high creep rupture strength, high high-temperature steam corrosion resistance, sufficient toughness, machinability and weldability. And the requirements of higher and higher boiler steam pressure and temperature parameters on the steel pipe can be met. The problem that an existing high-pressure boiler pipe is tedious and inconvenient to manufacture is solved, the manufacturing quality of the steel pipe is improved, and the high-pressure boiler pipe has the advantages of being simple in manufacturing process, few in used equipment and low in cost and is quite convenient to popularize and use on a large scale.

The present invention relates to monohydroindacenyl complexes as active catalytic components in the copolymerization of ethylene. The complexes are suitable for direct preparation of ethylene copolymers having a narrow molecular distribution as well as the desired levels of low density and preferably a predetermined value of glass transition temperature T_g. The produced copolymers showing improved elastomeric performance can be prepared in a single step during polymerization reaction, thus avoiding a blending step following the polymerization step.
